Question about Dishwashers

Dishwasher tub slowly fills with water after after completion

I have a Bosch dishwasher that is eight years old (model SHU9902UC). A few months ago I found clear water in the tub following a wash done the previous evening. I drained the tub by resetting the cycle as instructed in the user manual, but the tub gradually filled up with water again after several hours. This now happens after every few washes. When I turn off power to the dishwasher, the tub still fills with water. There seems to be a slow leak in the water intake valve, but I'm not sure why this happens only intermittently - that is every few washes. Do I need to replace the water valve? If so, what's the difference between the Bosch water inlet system (part No. AP2802392) and water valve assembly (part No. AP3783031)? Which part do I need? Thanks for your help

Re: Dishwasher tub slowly fills with water after after...

The internal parts of the valve are sticking open randomley.the diaphram/piston in the valve most likley have lime deposits on it due to poor water would need the water valve assembly but before you buy this part i would look where the water line goes into the dishwasher and it will lead you to the valve.remove the valve from the unit and disassemble the valve.clean all the internal parts in the valve and reinstall.75% of the time this works ,if not change the valve.

Dishwasher slowly fills after cycle

If water slowly fills in the tub when not in use.

a) Most likely your machine inlet water valve not seating properly and closing. Change the machine water valve.

b) May be sink drain water back flowing to the tub. But you have checked that.

So it has to be the machine inlet water valve.

My Bosch dishwasher fills with water but when it comes to the wash cycle it does nothing.

If your dishwasher is brand new, then call Bosch service as they can repair it under warranty.

My Bosch dishwasher is taking hours (at least 3 - maybe more) to complete a cycle. There is gummy, yucky stuff building up inside - sorta pinkish brownish. Could the water not be hot enough? A couple of...

if your on demand heater is one of the small ones that mounts under the sink, it will not flow enough water to fill your dishwasher. the dishwasher is waiting for the water level to fill before it starts washing. your bosch will heat its own water. hook it up to a cold line ahead of the water heater so that the fill valve is fed with full pressure. the residue sounds like detergent build up. when you get the water issue resolved, run a few cycles with no dishes and no detergent, on the highest temp setting. add a cup or two of white vinegar or dishwasher cleaner ( order online or get from an appliance repair store) through it. Dont forget your dishwasher has a filter in the bottom under the spray arm that needs to be cleaned periodically. if you dont clean it once a month it will get all kinds of nasty stuff built up in there.

Bosch dishwasher fills with water after cycle is completed

Sounds like you need a new water inlet valve. It's not shutting off completely, so water slowly enters the machine even while it isn't running.

Dishwasher: BOSCH SHE43 - pump keeps draining

Your dishwasher is stuck in flood mode. Bosch dishwashers are built with flood switches located in the bottom base pan of the dishwasher. The flood switch is connected to a rod that activates a small interlock switch. When water enters the base pan on a Bosch dishwasher, a Styrofoam puck lifts the rod, activating the flood switch.

When the flood switch is activated, the dishwasher will go into a no-fill, only-drain mode. The drain motor may also run with the door open to the unit. This is definitely a sign there is water in the base pan. This can be caused by the drain being clogged. There are two ways to fix:

1. You can uninstall the dishwasher and tip it forward to about a 45 degree angle to drain the water out of the base pan. (This is probably why Ian Bint's solution fixed the problem.) Be sure to put a towel under the dishwasher first so that the water is soaked up in the towel instead of going all over the floor. Once you've drained all the water out of the base pan, reinstall the dishwasher and begin a cycle. If it fills and runs, you are good to go.

2. You can also unplug the unit, then remove the kick panel at the bottom in the front. (It's attached with two screws.) Then get some old washcloths or small towels and reach into the base pan below the dishwasher to soak up the water. The pan is directly behind the plastic base panel rim. Once the pan is empty and dry, your dishwasher will no longer be in "flood mode" and will run properly.

If the base pan keeps refilling with water and the no-fill problem returns, there is definitely another issue, such as a clogged drain. At this point, you need to decide whether to invest in an expert evaluation by a certified Bosch repairman and make the necessary repairs, or buy a new dishwasher.
