Question about Bosch 23 in. SHU33A Built-In Dishwasher

1 Answer

Bosch dishwasher model #shu33A

Our D/W has been working just fine UNTIL we had a problem with our plumbing - our sinks would not drain & when hat happened the bottom of the D/W filled with dirty water. We "snaked" out the line & now our sinks drain fine. We drained out the water in the bottom of the D/W, but when starting a new cycle, nothing happens - no water comes into the washer & it doesn't cycle. We have tripped the breaker, but still nothing. Please give us another suggestion of what we can do. This D/W is only about 3 years old. HELP!!!

Your dirty water backed up into the washer (which it shouldn't do) and probably clogged something in there,..i would recommend getting it flushed out somehow, not sure how,.....next time, your washer drain hose should go up under the sink as high as possible and then back down to drain,....this settup makes it hard for drain water to go back into washer,....it's instructed in any dishwasher manual

Water comes into dishwasher cold. why???


Hello,

Welcome to FixYa.

Have you insured the unit is connected to a hot water supply line ? The water will not heat until it start's to circulate and activates the "flow switch" in the Bosch dishwashers.

If it is connected to a hot water supply, try running the hot water at your sink taps before turning on the dishwasher. If you still do not have hot water, check your hot water heater or supply.

If it is indeed connected to a cold water supply it will work, just be prepared for very long wash cycles since the Bosch machines will heat the water at a rate of 2F per minute...it could take a long time to reach 155F.

Let me know what you find out and I'll try to assist you in any manner I can going forward.

Regards,

Macmarkus :)

Not Rinsing


By cleaning it out, you cleaned the bottom where the water is drawn in and food particles collect, right? Are the sprayer arms working good? The holes on them are not clogged with anything? How does the dishwasher drain? I mean do you have an air gap or does it drain directly into the disposal or sink pipe. Sometimes without an air gap, the disposal will send junk into the drain line if the check valve is not working properly, thus giving you excess food in the dishwasher.

I have a Kenmore quiet guard 3 model: 665.74364k2 and serie F55202295. It is not draining properly. It works fine and cleans the dishes but when it goes to drain it leaks in my basement ceiling and vents.


if you have an air gap vent in the kitchen sink plumbing then make sure it is clear. Also looks like the kitchen drain end is blocked. Pour some caustic soda into the sink drain, wait 10 minutes and run water into the sink.

If you are using insinkerator (garbage disposer) in sink, make sure it is run before you start the dishwasher.

Water not draining after wash. Checked the troubleshooting guide and none apply to problem. It seems like the pump isn't running.


Have you purchased a new food waste disposer for the kitchen sink area? If so, make certain if you are draining the dishwasher directly into the food waste disposer, that you have removed the plug from the food disposer. Or you may be correct that the water pump is inoperable due to an obstruction or basic malfunction. Contact an appliance service company.

I have a bosch shu33a dishwasher and its not draining at all. it washes the dishes but the water wont drain out


Remove the lower front panel and you will see the drain hose leaving a tiny pump and heading out of the dishwasher space into the sink space where the drain line is attached to your drain line.

Remove the clamp on the drain line closest to the little pump and then unscrew the pump. you are looking for an obstrution in the form of a piece of broken glass, a bone, or something else which is preventing the pump from pumping the water into the sink drain.

please rate my answer as a fixya!

Bosch SHU33A won't drain


I believe you, but did you check the nipple on the drain where the hose connects?
My sink drained OK, and when I took the dishwasher hose loose from the sinkdrain it drained great into a bucket.
When I stuck a screwdriver down where the drainhose connects to the sinkdrain, I felt all kinds of resistance. Its now cleaned out and the dishwasher drains again.
Hope this is your problem otherwise you may need a new pump.
