Question about Dishwashers

1 Answer

Our Bosch dishwasher #SHU9922UC (FD8007) will not turn on properly. Only its drain pump starts -- and keeps running -- when it's powered on and the door's closed. Pressing the two "drain cancel" buttons for more than 3 seconds doesn't help. Neither does cutting off power, then turning it back on in the hopes of resetting the machine's 'computer'. No water inflow occurs. Help?

    Thank you! Some sediment had caused the drain level float to stick, and just jiggling its stem fixed the problem!

I had a similar issue after I replaced a bad drain pump, seems the logic got hung up.. I poured in a pitcher of water, closed the door, it drained and was then ok - worth a try. If not, you may have a bad water level switch.

Bosch dishwasher does not drain water and does not run


Bosch,. like many others have a "safe: cycle where the machine will always do a short pump out before it starts any cycle. If it fails to do a pump out even if there is no water in the machine, the machine will go into safety mode and will not allow a program to start. You will have to pull the machine out and check if the drain hose is blocked or kinked, and that the drain pump is not blocked or jammed. Toothpicks, bits of food and broken glass fragments are good for blocking / jamming dishwasher pumps.

I have a Bosch SHE55C05UC dishwasher and it just started to not wash properly and leave water in the pan below (first time it did not drain at all.. I tried the rinse/hold cycle and got the unit to drain...


I am assuming you have checked the filter and drain sump and there are no obstructions. Have you tried taking the drain pipe out of the sink downpipe and checking if it drains directly into the sink?

I am also assuming the wash cycle is completed when you open the dishwasher.
Do you hear the drain pump running?
Post your comment after you have checked the things I mentioned.

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.

SHU9922UC doesn't get rid of water


HI, check the following areas to address this poor draining issue.


1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.

Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.

3. Pump
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

Drain pump runs continuously. Nothing else happens!


Water had accumulated in the sump - a plastic tray at the bottom of the dishwasher which catches any leaked water. This operates a float switch which makes the drain pump run all the time. The fix was to tilt the dishwasher backwards to drain away the water. It isn't filling up again, so I'm not sure where the water came from, but I'll keep an eye on it!

Bosch Dishwasher pump keeps emptying


Disconnect the power to the unit. Remove the lower access panels and check the tray under the dishwasher. You will probably find it is full of water. Use a towel or a sponge to remove the water. There is a float that will stop the operation of the unit and run the pump if water is in this tray. Test the unit. If there are no leaks, check the drain hose under the sink. THE DRAIN HOSE MUST RUN UP TO ABOVE THE TOP OF THE MACHINE THEN TO THE DRAIN. If the hose is not set up like this, water from the sink drain will flow into the dishwasher and overflow into the tray under it.

If there is no water in the pan under the dishwasher there may be a problem with the pressure switch at the side of the pump housing but the only way to know for sure is to do some electrical testing with a volt/ohm meter and the wiring diagram located within the appliance.

Bosch SGV43A03 DISHWASHER: pump drains all the time, even if reset!


Typically you could possibly have a leak in the base or sump which activates a little float switch. This in turn switches the drain pump on continuously and deactivates the programing cycle.Sort out the leak.
