I just replaced the water inlet valve (part number 425485) for my Bosch Dishwasher (Model number SHU9955). When I turned my dishwasher back on the dran pump just runs and runs. I cannot turn it off. Any idea as to why this is happening? I have not had any trouble with the drain pump. I was not getting any water into the tub so I thought I should replace the water inlet valve. Now I just have a drain pump that won't stop running.
Answer Kyle, You'll need to check the base of the dishwasher for water accumulated on the base, (You'll need to remove the water valve and use a mirror to check). and check and make sure the "flood switch" or float are not "stuck" 00165301. If these components stick or there's water in the base of the machine, due to a leak or spillage The control interprets that as a flood situation and the drain pump runs to reduce the possibility of a "flood".
My dishwasher is stuck in the middle of the cycle. Even when I turn off the electricity from the breaker switch and turn it on again. It is still stuck mid cycle. A repair man thinks it is the control module that needs to be replaced. However he said it is a non-returnable item. At $300 plus I want to be sure I am getting the correct piece. If it is not the problem, can I return it for a full refund?
Answer Hello Lawrence,
I need to get some more information from you. Does the unit sound like a pump is running all of the time? If so, It sounds like the flood switch has been activated in the base. You see, when a small amount of water accumulates in the base, the flood switch is activated and this causes the unit to do nothing but pump out. Most of the time the problem turns out to be a bad water inlet valve.
Remove the kick panel and turn the water and power to the unit off. I normally remove the door panel and the bottom sheet to accommodate more working space. Remove the water inlet valve and, using an inspection mirror and flashlight, look for any water in the bottom of the unit. If you see water, I always use a towel not washed with softener to wick the water out. Be careful while doing this as the float switch is made of Styrofoam and can easily be damaged. You should replace the water inlet valve 00425458 as this is normally the cause of the waters' presence in the base assembly.
