inlet valves.

- Verify inlet valve operation.

1. Verify there is not a siphon problem.

2. Press PAUSE/CANCEL twice to clear

the display. The machine will drain for

3minutes before unlocking the door.

3. Unplug washer or disconnect power.

4. Verify wire harness connections to

inlet valves, pressure switch, drain

pump and Central Control Unit (CCU).

5. Check all hoses for possible leaks.

6. Plug in washer or reconnect power.

7. Verify pressure switch operation.

8. Verify CCU operation by running a

Diagnostic Test or any cycle.


most likely in your case the drain pump trap is clogged, the water doesn't drain so it wont call for water to fill


remove the access panel under the door # XXXXX on this diagram and clean the pump.
