I have a Bosch SHU9922. At times I have standing water (sits slightly below bottom rack) in machine. At times I have residual suds even after I've run it empty with no detergent. I had a repair man out, he blew into hose that runs to garbage disposal (after he thought it was slightly clogged) then ran machine and then hit cancel/drain and it drained. $90 gone...But problem still exist. It also seems that at times after I have scooped out water, water will reappear. All screens have been clean. No water appears to be in tray on bottom or appears underneath after running. I typically leave door slightly ajar on empty machine when I travel (to keep machine not smelly when return). Ended up having a water leak onto my wooden floor. I am handy woman and can follow a video etc but when it comes to strength…not so much. Any help would be appreciated.
