Dishwasher confused. It suddenly drains water, then it resumes cycle
The dishwasher had some issues before. From time to time it was beeping signaling it couldn't drain water while it was in fact empty. A workaround was just pouring a few liters of water inside, manually. This would allow it to complete the cycle.
However, since yesterday, I noticed my dishwasher starts the cycle but after a while it suddenly drain the water. When done, it tries to resume the cycle. But since there's no water anymore, I can hear the water pump (not the drain pump) running. If I pour some water manually, the cycle just resumes. Unfortunately, this drain-resume behavior repeats so the cycle itself never ends (or at least I kept doing it for three times without noticing anything different).
Any ideas? :)
PS: I have experience with repairs in general, but not with dishwashers.
Is this a good question?
