Dishwasher filling with water when it is not turned on, no is the door closed.

Hello, welcome to FixYa.


A very common problem for Bosch dishwashers of that era. A faulty fill valve...sticking in the "open" position.

It could be debris stuck in the valve, but I wouldn't chance it...just replace it for the cost is much cheaper than a new floor.

This is what to look for...



As long as your model is indeed a Bosch, this info below will be accurate.

Original part is # 425458. It usually retails for about $20 - $30USD at places such as "searspartsdirect.com" "repairclinic.com" to name a couple, if needed. They may be available at your local brick & mortar parts depot/vendors.

**Before attempting to repair the unit please turn off the power and the water supply to the dishwasher...safety first**


If you remove the lower kick plate/toe panel, you will see the inlet valve to your left...

i.e.



Replacing it or to check for debris in the filter/screen at the inlet is pretty straight forward. Here`s how...

1) undo the water line. ( here you can visually inspect the screen in the valve...if nothing noted, you'll likely need to replace it as follows )

2) Remove the two #20 torx screws fastening itdishwasher filling with water when - 156e176.jpg/i>



3) the feed tube to the machine at the dishwasher filling with water when - 5937279.jpg valve and swap it with the new one.
and



Once the new one is in or it's all clear you should be good to go.
