I have a Bosch SHE68T52UC/02 , bought in 2014. At the end of cycles, for the past 4 months or so, there is still some water and soap in the drain area above the pump and under the bottom wash arm. Also, the high loop is not that high and when draining is occurring, one can see backflow. (A pro who was installing a microwave thought that the (not high enough) high loop was an issue with the dishwasher)

I took 2 short videos of the issue:
2 seconds, suds after rinse only:
60 seconds, backflow in drain hose:

Do you think it's the high loop or the drain pump?

I actually just had it looked at by a dishwasher appliance pro, who fixed issues with the door, but the issue with incomplete draining / soapy residue remains. He's coming back in a week to see it in person and call Bosch over the phone; but he didn't get it right the first time, so I'm a little skeptical...

Thanks!

Too sudsie! Either you have very soft water, or the powered detergent is too much. I have a feeling with the amount of suds, your getting aeration, causing the pump sensor to cut off too soon. Try a quick wash without any detergent a few times, to clear out any soap, and check the level.

The other issue to cause a lack of emptying, is the dishwasher could be unlevel.

Thanks for the reply!
Nothing seemed to get rid of the suds until I tried vegetable oil and salt (from a web search) . Running several rinse only cycles with no detergent, or pouring vinegar in, or running with high temperature hadn't worked on getting rid of the suds. It *Does* seem to be draining and running better since knocking down the suds using the oil and salt. Without your post, the idea of the suds / aeration causing the pump sensor to cut off -- wouldn't have come to mind. It seems unfortunate that the pump / sensor would be designed like that.
I am currently using half pellets of Finish detergent now, and the suds returned only a little bit. This Thursday, the tech/pro who serviced it last week is coming by to look at the draining in person and call up Bosch tech support -- the first 30-45 minutes will be free for me.

Great to hear it helped. I am using Finish Quantum, though never used the pellets. At least now you are able to have a functioning dishwasher.
