Report "Hi, I have an AEG Favorit 525 dishwasher. It's over 20 years old, but has a panel on the front which matches the kitchen and it has done stirling service over the years. Lately, the knob has been sticking a bit mid cycle, but it has been intermittent. Last night, although the dishwasher sounds like it is working properly, it is not filling with water. Motor sounds like it is trying, but to no avail. If it was human, I would say prostate issues, but I don't think dishwashers have those. Any sugestions? Is it worth getting it serviced, or should we look at replacement?"
