Re-verify that the cold & hot water hoses are connected correctly (hot hose to hot valve & cold hose to cold valve).
Inspect the black tube on the WATER LEVEL SENSOR. It should be attached to the SENSOR and the tiny spring-clamp should be securely holding the tube in place.
Usually a *NO FILL* symptom will trigger an error message.
"nF" : No Fill
"LE" : Water Level Sensor Error
The WATER LEVEL SENSOR should give 22 to 24 OHMS at the *pink* & *violet* connections of the SENSOR (remove plug to test sensor).
If the WATER LEVEL SENSOR is "good"---start a cycle with HOT water selected.
The HOT WATER VALVE should be getting 115/120 volts AC (within 30 seconds).
Turn off the washer---turn on washer.
Repeat the test using a cycle for COLD water only. One of the COLD WATER VALVES should be getting 115/120 volts AC (within 30 seconds).
If not---try clearing the EEPROM...
Power off washer.
Press the following buttons at the *same* time:
Test washer functions again to see if water enters.
If not---order a new MAIN BOARD.
There are 2 versions of this washer (with the same model number). Use the SERIAL NUMBER to order the *correct* MAIN BOARD.
If a new MAIN BOARD has been installed---perform the EEPROM clear/reset procedure *again*. This resets the "computer" (new board).
If this is not done---it can appear that the new board is *defective* as the washer will not function properly (erratic operation).
