Question about Bosch SHU9922UC Built-in Dishwasher
I own a SHU9922UC, recently we started to have a bad smell coming from the unit. I went ahead and pulled it out, there is one hose on the back of the unit that was stuffed with mucus looking goo and it smelt horrible! Any idea what could cause this or what I can do to stop this? All help is greatly appreciated!
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.
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.

The smell usually comes
when the washer is unable to drain water completely, you can run your washer at
its hottest temperature setting with 1 cup of vinegar inside the unit. After
this take off the bottom front panel and clean it completely, also clean the
drain hose and drain pump filter, the smell should disappear after doing all
this. Hope this helps...please post back for further assistance.
