First Check the house outlet for the proper voltage.

Check for 120 VAC to the J101connecter BLACK to WHITE wires fromthe LINE FILTER.

If no voltage there, Check line voltage coming into the line filter from thepower cord connecter.

If you have voltage there, replace the line filter. If no voltage, check thepower cord connecter and harness for damage.

there needs to be water in

the tub.

For models equipped with a pressure sensor, thepressure sensor status will be determined byreading the pressure sensors frequency.

If the pressure sensorsfrequency is outside ofthe Valid Values then an error condition is set.The error condition will be logged in Service

mode.

If Pressure Sensor Error occurs during cycle, thecycle will be canceled and the control should goto Idle.

If a cycle is started during a pressure sensorerror, the Fill cycle will be cancelled.

Use a Hertz meter to readthe Hertz at specifiedwater levels.For testing at thepressure sensor, the pinout is as follows:

1 = Ground2 = Signal3 = 5V

With that, you wouldwant to test between pins
