I assume you are saying that when you start the washer it fills to the desired level, then stops filling and ceases any operation. Can you expand on the situation, and address these points.

1. Does this happen on all wash cycles?
2. Does the timer advance?
3. If you manually advance the timer to the rinse cycle, will the machine
a. empty and spin?
b. refill and go into the rinse cycle?
4. Same question at end of rinse cycle?

5. Did this happen gradually or all at once?

Anything else you think would be helpful, please add

Thanks and lets see what this tells us.
