How to repair the Bosch dishwasher that won’t drain

appliancesdishwasherrepair

My Bosch dishwasher stopped draining. At the end of the cycle, it gets stuck at 1 minute remaining. When I open the door, there's water that hasn't drained.

Here's what I've tried:

Following the instructions from a video on YouTube, I emptied the water, removed the cover on the drain pump impeller, removed any additional water and debris, took out the back flow preventer, and removed additional water and debris.

After doing this, the first two times I ran the dishwasher it did not fill with any water.

I then poured some water into the bottom of the dishwasher to see if it would drain and started another cycle. This time, it did fill with additional water, but I'm back to the original problem. It doesn't drain at the end, and it gets stuck at showing 1 minute remaining.

You've got some large particles in there & it seems that you're running out of time before a complete draining. You likely have a partially blocked drain line from the sink side of things. Make sure your drain hose is clear to the sink drain or disposer & that your sink-top Air Gap (if you have one) is clean.

Your drain hose should enter the sink cabinet at the very top & your hose should be angled up from the sink drain or disposer inlet with no sag or dip below the top of that inlet to avoid any future clogs. You should be good to go after that's all squared away.
