I have a bosch SHU3307UC/U12 all 4 lights on the panel are on and unit seems to be non -responsive

Hello, welcome to FixYa.

Based on your post I understand you have a Bosch SHU3307UC dishwasher, correct ? Firther to this you.ve stated "slowly fills the bottom between cycles, even with little or no activity at the sink"

It sounds to me like the fill valve is at fault unfortunately. This is a very common problem for Bosch dishwashers of that era.

A faulty fill valve...sticking in the "open" position either due to the plunger in the coil getting stuck or sediment inside the valve body impeding it from closing correctly...Either way you're safer to change it with the history of these valves failing.

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 it in place.



3) the feed tube to the machine at the back of the 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.

Put dirty stuff in will eventually keep a tech like me very busy. We love to come and charge you alot for cleaning your dishwasher. Remember the Maytag commercials where they put a cake in it? Still got the dishes clean but before long it will cost you big time. Just run everything under the tap. Pot and pans should be lightly washed also. Watch how you place the dishes. Most dishwashers spray up from the bottom. Block it, and the spray will not reach the top.

Hi,

The scum, film and white residue problems have started since the reduction of phosphates in dishwasher detergents.

Here is a tip that will help you to solve the problem of films, residue, and scum in your dishwasher.

THE WATER GOING INTO MACHINE IS NOT HOT. LET WATER RUN UNIT IT IS HOT THEN START THE MACHINE. HEATER ONLY FUNCTION IS TO MAINTAIN THE HEAT , IT DOES NOT GO FROM COLD TO EXTRA HOT

You have to allow the drain cycle to finish completely, or find cancel drain dot points and press both at the same time, to reset program, open the door and close it to make sure the micro-switch activate properly

bosch dishwashers will run forever if it can't get the water to 150 degrees. it can't get it there because either the heating element is bad, or the solder joint on the control board that contols the heating element is bad. you can order a new board, of if your mechanically inclined you can take the board out and resolder the bad spot

you need to remove the front panel of the dishwasher. you need to open the door and remove the 6 torx screws on the inside of the door, close the door and lift up and out to remove front panel. you wiil see the detergent assembly there
