CONSTRUCTION

The front loading, tumble action clothes washer con-sists of a perforated, cylindrical'tub suspendedhorizontally.on its axis within a larger solid cylindricalttjb. This assembly is suspended by springs within afour piece steel cabinet. A see through door and allexible bellows (seal) provides access for loading andunloading clothes. The control console configur,ationprovides the versatility ol stacked or undercounterinslallations.

The washer is shipped with a painted top panel, but agalvanized panel is available.if the washer is to beinstalled undercounter.

CONSOLE

The controls are mounted on the front of the cabinetand are accessibleforservice by removing the washertop service panel. On stacked installations, the dryermust be removed from the washer.

CABINEI .

..

The cabinet is made of heavy steel in a four piecedeslgn with an enarnelfinish. The sides and front areriveted at the front corngrs ahd base. The,'iear of thecabinet is galvaniZed steelandis securedwith screws.

FROI.IT PANEL'AND DOOR ASSEIIBLY

The front panl is riveted to the'si$e pahels for maxi-mum strengh and structural rigirdi.ty; ]

BELLOWS

The bellows is a rubber sleeve that seals the sus-pended outer tub to the stationary cabinet front at thetub opening. lts purpose is to provide a water tightopening into the tub that can be seafed by the cabinetdoor, yet allow flexibility for the oscillation of the tubduring the wash and spin cycles.

OUTER TUB ASSEMBLY

The outer tub assembly is supported by two suspen-sion springs and stabil ized by. ' two air shockassemblies. Cement counter weights are mounted tothe outer tub front (top & bottom), and the rear top.These counterweights prevent excessive oscillation ofthe entire suspended assembly during an unbafancedspin cycle.

INNER TUB ASSEMBLY

The inner tub is constructed oJ stainless steel. Thecircumference of the tub is perforated to allow water toflowthrough the tub as it revolves. A heavy steelshaftis pressed into the tub support which is bohed to thetub. The tub is supported by two ball bearings pressedinto the rear of the outer tub.

A large drive pulley is mounted to the free end of theshaft that extends through the rear of the outer tub.

There are three plastic vanes mounted to the tub to aidin the washing'action during the wash cycle. Therotation of the tub provides both the washing actionduring the wash cycl6, and water extraction during thespin cycle.

DRIVE SYSTEM

The drive system consists of a reversibfe, variablespeed, 16 pole DC motor coupled with an eleclronicspeed control unit and timer. The motor drives the tubpulleywith aG rib Poty-Vbelt. The motorrotatesthetubat 52 RPM in a 16 second cloclcwise/countercloclcwisemotion with a 4 second pause at th.e end of eachtumbling wash action.

The drive motol rotates the tub counterclockwise up to650 RPM for further water extraction after certain draincycles. lf an unbalanced wash load prevents thewasher from reaching fulf spin.speed, the electronicspeed control adjusts the spin speed back to agitatespeed to allow the wash load to self adjust. Then themotor will again attempt to dri.ve the spin basket up to650 RPM This procedure continues.lo repeat as neces-sary.

ELECTRONIC SPEED CONTROL J

The electronic speed control monitors current drawand a built-in tachogenerator in the drive motor, locontrol RPM of the tub during wash and spin cycles.

DRAIN SYSTEM

The drain system consists of an air cooled, AC motorpump assembly, a bellows type sump hose, air bell,and a ribbed drain hose.

The drain pump and motor assembly is tocated in theright front corner and is mounted on the base. When thewasher rinse cycle is completed, the timer energizesthe pump motorto remove waterfrom the tub before thespin cycle slarts. The pump motor remains in operalionthroughoutthe spin cycle. The pump out'rate is approxi-matelyS GPM underfullload operation, which emptiesthe tub whhin 60 seconds.

SUSPENSION AND STABILIZER SYSTEM

The entire tub assembly is suspended by two springs.The stabilizer systern consists of two air shocks that arelocated between the outertub and base, one per side.They provide a dampening action to stabilize tub as-sembly during spin cycles.

DOOR SAFETY SWITCH ASSEMBLY (Door Lock)The door lock consists of a bracket to which is mounteda solenoid, door switch, and PTC. When the door isclosed and the timer seleclor knob is pulled oul, thesolenoid is energized, which locks the door and closesthe door lock switch through a series of levers on thedoor lock assembly. Ths door is loiked whenever thewasher is in operation to prevent the door from beingopened.

Door Switch

The door switch is snapped into the door lock mountingbracket and is secured withtwo springtabs, The switchis actuated by the solenoid ratherthan the door. Closingthe door causes the door strike to push the small levelupward into the 'standby" pOSition. When the user pullsthe timer knob out, the solenoid is energized which pullsthe spring loaded bqacket and locks the door. Thislocking motion is trdnSfened by the vertical lever to thedoor lock switch: Using the door locking molion toactuate the switch ensures that the door is cloSed andlocked before the switch is closed.;''

_ , _

lf the user attempts to start a cycle with tha door open,the solenoid is actuated but the washer will not start fortwo reasons. One, the door will not close because thelower door strike cannot pass through lhe openingwhile the solenoid is energized, the door just bounceiopen when attempting to close. Two, the door lockswitch cannot cfose because the small lever is not inthe "standby" position with the door open.

Door Lock AssemblyDoor Lock Assembly

Solenoid

The solenoid is energized whenever the washer is inoperation to prevent the door from being opened.

Door Lock PTC (Positive Thermal Coelficient)The PTC acls as a resistor or heat source to warm abimetal that actuates a small rectangular pin whichholds the solenoid in its retracted position even whenthe solenoid is de-energized. During spin, the PTGlocking pin engages a catch in the spring loadedbracket that locks the loading door in the closed posi-tion. This locking pin will remain in this position longenough forthe tub to come lo a complete stop (approxi-mately 40 - 65 seconds). As the bimetal cools, thesolenoid will release, and the door may be opened.

Door Lock Assembly

TIMER

Gontacts within the timer control the direction of thedrive motor, water fill, drain pUffip, doorlock, and endof cycle signal. a*-^The timer provides four separate washihg cycles: Knits-& Delicates, Perm Press, Regular and Prewash.

Regular Wash Gycle

The Regular wash cycte proviries up lo 18 minutes ofreversing tumble action for most fabrics. Three rinsesand a high-speed finalspin complete the cycle.

. Wash provides 18 minutes of reversing tumbleaction for normally soiled fabrics.

. Light Wash provides 14 minutes of reversingtumble action for lightly soiled fabrics.

Perm Press Gycle

The Perm Press wash cycle provides up to 13 minutesof reversing tumble action for permanent press gar-menls. Three rinses and two spins complete this cycle.Gold rinses are aulomatically provided when the PermPress cycle is selected.

To help reduce wrinkling, Perm Press cycle does nothave a final high-speed spin.

Knits & Delicates Gycle

The Delicate wash cycle provides up to g minutes ofgentle reversing tumble action, which consists of 3.3seconds of agitation followed by a 17 second pause,which repeats for the duration of the cycle. Two rinsesand two spins complete the cycfe. Cold rinses areautomatically provided.

Prewash

During prewash, the washer will tumble the load for 6minutes, drain and spin.

NOTE: For detailed information on Laundry prepara-tion, sorting, factors affecting performance, andlaundry products, refer lo the Olner's Guide.

For best results, follow fabric care label directions onspecific items to be washed. Check Operating Instruc-tions "Control Settings Chart" if the care label is notavailablg.

WATER TEMPERATU RE CONTROL

Water T: tnperature Selector' - . . ' ' .

The watertepperatures forwashing and rinsing are setby using thewatertemiierature seleclor. Turn the.knobto the desiredwater temperature combination. Severalwash/rinse watet lemperature.combinations are avaiF-able. Selections are:"COLD-COLD",1A/AR[/FCOLD",'VVARM-WA R M","HOT*COLD', (and"l{OT-WARM, notusedon domestic modeb).Gorrect water temperature is necessary for good wash-ing results. To help determine the best washtemperature for particular loads of clothes, refer to thefabric care label directions on items to be washed.Check Operating Instructions "Control Settings Chart"if the care label is not available.

WATER LEVEL CONTROL

The water level control provides the proper amount ofwash and rinse waler, but is not user adjustable. Thebulkiness of clothes is often more important than theirdryweight when determining a water level. Articles thatabsorb a large amount of water, such as pillows,blankets, and rugs require.more waler than indicatedwhen they are weighed. The water level control willaulomatically provide more waler with these loads.The water level controlis a pressure activated single-pole, double-throw switch connectedto an air bell atthesump housing. A black rubber hose connects thepressure switch to the air bell. lts purpose is todetermine the water levelwithin the tub and controltheoperation of the water fillvalve.

WATER FILL VALVE

The two coilvalve assembly is mounted on a bracketandfastenedto abrace atthe upperright rear insidethecabinet. Raise the top panelfor access to water valve.

Under normal operating conditions, it takes severalseconds forlhe valve to completely close and stop thewater flow after the solenoid circuit is opened. Thisprevents water hammer. The water valve llow rate is4.50 GPM at 20 PSI and 7.0 GPM at 120 PSl.WATER VALVE INLET SCREENS MUST BE KEPTCLEAN AND IN GOOD CONDITION. A PLUGGEDBLEEDER HOLE IN WATER VALVE DIAPHRAGIVTOR MINERAL DEPOSITS ON THE ARMATURE MAYCAUSE THE WATER VALVE TO FAIL AND RESULTIN CONTINUAL WATER FILL. .

TIMER

The timer interfaces with the electronlc speed controlunit and the,drive motdr, and performs the fofl6.wingfunctions:

1. Provides AC power to the electronic speed controlunit.

2. Reverses the direction of the DC drive motor, byreversing the polarity on the motor brushes.

3. Controls the entire timing sequence during the cycleselected.

j ' .

TIMER OPERATION

The timer works with the electronic speed control in a"Master/ Slavei type relationship. The timer (ormaster) tells the efectronic speed controlwhat to doand when to doit, and the electronic Speed controlcontrols the motor speed functions such as ramp-upand speed monitoring. tl;The timer is an interval timer like previous timeB butthe step times can be various lengths (i.e. 3.3, 50,100, 146.7, 150, etc.) versus fixed. This allows.thetimer to be more llexible. The entire agitation portionof the wash cycle can bb contained in one step andnot spread over many steps.

The timer contains two sets ol cams that driveswitches, and foUr cams that are used to count time. i 'The cams are driven by the timer motorthrough a setof reduction gears and a crank and pawl assembly;,The fast cam controls the reversing tumble action of .the drum by reversing the polarity ol the DG vohage tothe drMe motoL lt also signafs the electronic speedcontrol through codes that the polarity is changing andthe electronic speed control should stop the drivemotor, allowthe timerto change polanty, then resumemotor rotation. The slow cam controls the timingandfunctions of the other components within the washersystem (i.e. pump, waler valves, etc.).The timer also interfaces with the dispenser systemand defines when to dispense detergents, bleaches,and fabric softeners. The shaft has a cross shapedfealure that mates with a matching feattire on thedispenser cam. The dispenser cam profile is designedto match the program set within the timer. ir,Timer Operation During Wash Mode

The timer has four wash cycles that may be chosen(Pre-Wash, Regufar Wash, Permanent Press, and .Knits and Delicates). Onlythe Regularwash has twodifferent startingipoints, the first provides for a longerwash for heavier soiled clothes and the second fornormally soiled clothes.

ll the timer dial is set to the start of Pre-Wash, Perma-nent Press, Knits and Delicates, or the second start ..,position of RegularWash, the timer witlwaii forthewater levelpressure,swilch to be satisfied beforeagitating the clothes load. Only in the first startingposition of the Regular Wash cycle willthe timer allowthe clothes to tumble while the water is filling the tub.

To understand the timing'sequence of the fast cam :during agitation, let's look at an example of whathappens during a Rggular wash cycfe beginning at

. the second starting position. The slow cam sets upthe watertemperature switch,to provide hot, warm orcold wash water by closing contacts 64 and 88, itprovides part of the agitation code (code A) to theelectronic speed controlby closing contact 9A, and itsets up the to operate on the fong field winding by i...,=cfosing contact 13A. j!

j r ::' The fast cam rotates one full revolution every 20(F=' ' *

seconds (3.33 minutes). Every 16,67 seconds thecam opens fast cam contact 24Btor 3.33 seconds.

' This interrupts the agitation signal code (code D) to"the electronic speed cpntrol. The electronic speed .controlthen turns off the drive motor. During this OFFtime, fast cam contact 21 will switch from 21A to 218and contact 23 willswitch from 23A to 23B to reverse

the polarity of the DC motor vottagbto the iirirr6'molor. At the end of the 3.33 second time period, fastcam contact 24B closes, returning the agitation code(code D) to the electronic speed oontrol. The elec-tronic speed controlthen tums the drive motor ONagain. This "reversing" process continues, with thefast cam contacts switching back and forth, for theduration of the wash time remaining.in the wash cycle.

", The fasl cam profile is designed to tumble the clothes' load 1 time CW, 1 time CCW,2 times CW, 2 timesCCW as viewed from the front of the machine. Duringthe first few tumble sequences, the drum fidy rotate ,.,'in the same direction three or fourtimes before'changing directions. This is normal. A specialcamwlthin the timer must cycle through a sequence beforeit "unlocks" the reversing protection arm built in the

, timer. This feature ensures tha[{he drive motor is notallowed to turn ON in the oppotite direction if it werecoasting down from a high spedd spin and the timerwas advanced into an agitation cycle.

Timer Operation During Spin:Mode. . :

To understand the timing sequence of the timer duringspin, let's look at an example of what happens duringa Regular wash cycle before thetimer advances intothe first spin. The slow cam sets up,the watertem-perature switch to provide cold rinse water by cfosi,qg .contacts 68 and 8A, the electronic speed contiolspin'code and door lock thermal salety delay deviie'(PTC)is turned on by closing contact 48, the pump istumedon by closing contact 78, and the motor is set up tooperate on the long lield winding by closing contact13A. :

The timer has three different rinse phases. Withineach phase the timer aghates, drains, and spins. The,'timer basically providgs a signal code to the electronicspeed controlaiid lets it conlrolthe motor motion:

:*fn the rinse phase, the timer calls for an impulse spin,wheretwo short ramp-ups and spins occur. The timercloses slow cam contacts 48 and 9A sending thesignalto the efectronic speed control to generatethese spins.

'ln the second rinse, the timer calls foia normal rampup and spin speed at 450 rpm. The fffibrdisables thefast cam and closes direction contaits 21A and 23A-_with a reversing protection lever that ensures thecontacts are closed at alltimes during spin. The drivemotor is also set up to operate on the long fieldwinding by closing contact 13A.

' - 6 y ' t4 f f l iF ;C - t ;

In the third spin, the spin is a two part spin. The timercloses direction contacts 2lA,and 23A, and set thbdrive molorto operate on the long field winding byclosing contact 13A. After 200 seconds of spinning at450 rpm, timer contact 13A switches overto 13B:energizing the drive moto/s tapped field winding anddisabling the fong field winding. Sfow cam contact gBcloses sending the signal to the electronic speedcontrolto accelerate the drive motor to 650 rpm.

Within the middle of the second rinse phase (Regularand Permanent Press onlyJ is an Extra Rinse cycle.The Ctow cam will try to enable the pump by closingslow cam.conlacl TA. It the Extra Rinse swhch is set ;to the YES or ON position, the pump willturn on anddischarge the water for 50 seconds. The timer willthen fitl the tub with,water and resume agitation. lf theExtra Rinse switch is set to the NO or OFF position,the timer will signalfhe electronic speed control togently tumble the ctothes load by closing slow camcontacts 98 and 248.

.,..

At the end of the wash cycle the timer pause for 50seconds to allow the spln tub to coast down to acomplete stop. During this time, the timer disables allthe electronic speed:controlcode signals, and re-leases the door lock thermal safety delay device(PTC). Atthe:end''of 50 seconds, the timerwillcloseslow cam contact 44 energizing the cycle signal

WATER LEVEL CONTROL

The water tevel control is a pressure activated single-pole, double-throw switch connected to an air bell at thesump hose. A black plastic tube connecls the pressureswitch to the air bef l. fts purpose is to determine the waterlevel within the tub and control the operation of the waterfill valve. As the waler level rises in the tub, air in thepressure tube is compreissed and forced against thediaphragm in the water levelcontrolswitch.

DO NOT ATTEMPT TO ADJUST THE RANGE OFTHE WATER LEVEL CONTROL

To Test Water Level Controt:

Do not condemn a water level control until the entiresystem has been examined and tested. For example, ifthe air bell, located at the sump.area, has filted withwater, the water level controlwill overfill the tub.

The armature spring is compressed bythis action. Whenthe armature moves up, it allows the water on the top ofthe diaphragm to drain through the main orifice.

The diaphragm bfeed orifice is much smaller than themain orifice andwillnot admit enough waterto rnaintainpressure on the tbp slde of the diaphragm. Thus, as thepressure on the top of the diaphragm is reduced toalmost zero, the pressure on the bottom lifts the dia-phragm off the vafve seat, allowing a full flow of water.

AIR BELL AND PRESSURE CONNECTING TUBE

In orderto provirJe enough air pressure to ac'tivate thewater levelcontrolswitch, a large volume of air must becompressed and transferred to the water level control.This is accompfished by using an air bell and blackrubbertubing.The airstored in the air bell is compressed bythe weightof the water in the tub. The resulting pressure is thentransferred to the water levelcontrol through the blackrubbertubing.

To Remove or Heplace Air Bell:

Disconnect washer from elec,trical supply.Remove two screws securing the front servicepanel.Remove the service panelby pr.rlling down.
