Bosch SHU9915 Does Not Drain

Hi my Bosch dishwasher isn't draining anymore. I ran a couple of rinse and hold cycles to see what it does, and after rinsing with good pressure, it pauses and then signals end of cycle without draining. It leaves water almost over the door seal level. I think the level sensor works because it doesn't add more water if you cycle it again. If you bail out the water and run it, it will does refill. Looked at the little blue impeller under the cover in the bottom and it turns freely. Any ideas, sticky valve, faulty controls? Thanks in advance.

    How do I run a test program to check the module? Where can I find a troubleshooting chart for this model? Specifically, mine is a SHU9915UC/U12. I want to be sure since the board is expensive. Thanks.

    ** warranty, all on my dime. Looks like a module is $115.

    Just wanted to close the loop and let you know what the real problem was... I called my local appliance parts dealer, KenWhirl in Dearborn, MI and the immediately said, well you know Bosch has a seperate drain pump, sounds like you need a new one. They had it in a couple of days and that was indeed the issue. Courious I couldn't find good advice here.

    Machine
    fills and runs with short breaks that resemble those switching program
    cycles. Water heats normally. HOWEVER, NO WATER IS PUMPED OUT AND
    MACHINE REMAINS FULL AT END OF WASH. please advise,

    Repair clinic answered:"Check the
    drain valve for restriction in the pump and check the drain line to see
    if it is plugged. Note: If a new garbage disposer was installed, remove
    the knock out plug for the dishwasher drain."

    SHU...does not seem to have a drain pump (at least Repair Clinic has no replacement part) - is there a diverter valve for draining instead? Did Fritz27 actually see such a pump. I looked underneath and did not see anything resembling a pump.

    Before you raplace the pump, make sure you have power there, when it sould drain, if not, you have a faulty circuit board

Hi,

If I may add and with the indulgence of IB4G2008 and Jaime867.....
Have you physically checked the drain, drain filter and drain hose for any blockage, clog, kinks and/or anything out of the ordinary pls?

You can also try running a slightly above pressure hose backwards from the drain and try to see what comes out in the drum.

Good luck and kind regards.

    of course, could also be the relays..but since most of these are integrated circuits, you wind up changing the board anyhow.

    unfortunately it's more of a workbench issue. swap outs these days, instead of component level troubleshooting...this still under warranty?

    well..then that's how it's gonna go..the change isn't that tough, actually...a little patience will do it..

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.

Bosch dishwasher shx55m with bottom tub full of water


The dishwasher really shouldn't pass any particles near large enough to clog the drain hose. It sounds more like a mechanical issue. Check the circuit breaker to make sure it's not tripped. See if you can hit a cancel button or something to make it drain. Try to run another cycle. If the computer is stuck or acting funny, trying cutting the power for a while, holding down a stop/reset/cancel button, or running a cycle that you don't usually run. I had this kitchenaid that would randomly refuse the normal wash cycle, but would run fine when you ran rinse only or something, then regular wash and everything would be fine again too. If the line somehow is clogged, there's a good chance it's right where the hose connects to the disposal or drain pipe.

Our dishwasher does not progress beyond the wach cycle to the rinse cycle. It will run for hours and still has soap in it.


I'm positive of this, but your dishwasher may qualify for a somewhat recent recall. Call bosch to see. If you can get it to drain manually and put into rinse and hold manually, but it won't progress on it's own, then it's the control board. Hope this helps.

Bosch dishwasher has standing water doesnt drain out, repair man pushed 2 buttons cancel drain and it drained last month, but happened again today and it wont work for me


Fixed mine very easily... After checking and cleaning the filters by the tub's drain, I checked the air vent atop the sink -- it had a small bit of gunk trapped in the outlet. Cleaned it out, ran a "rinse & hold" cycle and it drained the tub beautifully!

Bosch SHU43C


My SHU43C is just over 3 years old. I had a similar problem recently. First, there were a few floods. Then, the Bosch only drained non-stop. Even when I used the Cancel Drain buttons the drain pump would run without stopping. When I tried to run one of the cleaning cycles, no water entered the machine. Corrective: I removed the base plate, and saw that the red plastic floatation device was in the up position. Using a flashlight and a wooden spoon, I lightly toggled the red float stem down. I pushed regular clean cycle and kept toggling with the red float stem until the rinse water started to enter the machine (turning the red stem seems to also actuate a step in the program). Now the dishwasher runs normally. Voila!

Bosch Dishwasher Not Draining


Im really not all that familiar with the bosch unit, but a few things i would ck. when you cancel a cycle (it should drain the water) is it humming??? does it sound as if it even trickling into the sink discharge?? do you have a disposer under your sink that this unit drains into, if so remove the clamp and look for possible obstructions right there.Honestly passed this ill have to defer to someone else sorry and good luck
