Bosch Dishwasher water at bottom

What to expect when you experience a Bosch dishwasher leaving water at the bottom of the tub

How do you troubleshoot a Bosch dishwasher leaving water at the bottom of the tub?

Fixing most issues causing your Bosch dishwasher to leave water at the bottom of the tub often involves replacing a leaky fill valve, a clogged or damaged drain hose or a bad drain pump motor. However, there are many other potential causes including:

• Clogged sink drain.
• Clogged air gap.
• Bad electronic control board.
• Wiring failure.

Follow the troubleshooting tips in the owner’s manual for your Bosch dishwasher when it won’t drain properly. If the basic troubleshooting tips in the manual don’t help you fix the draining failure, schedule repair service to have a Sears Home Services technician visit your home and fix the dishwasher.

What are the main causes of draining failures in Bosch dishwashers?

When your Bosch dishwasher leaves water at the bottom of the tub, one of the main causes is a clog in the drain path through the kitchen sink. Sometimes, a garbage disposal that is full of food scraps will prevent the dishwasher from draining. Run the garbage disposal to clear that drain path if the garbage disposal if full of food scraps.

If the kitchen sink drain is clogged, the dishwasher won’t drain. Clear the kitchen sink drain using a plumber’s snake or have a plumber clear the sink drain if it’s clogged.

If your dishwasher has an air gap installed in the path to the kitchen sink drain, check that component for a clog and clear it if necessary.

Grease buildup at the end of the dishwasher drain hose is another leaking cause of water staying at the bottom of a Bosch dishwasher at the end of the cycle. Clear the drain hose if it’s clogged with grease.

What to expect when having a Bosch dishwasher drain problem fixed

When your Bosch dishwasher is not draining properly, expect the technician to first run a test cycle and verify the problem. The tech will then check the basics such as whether the sink drain is clear and whether the garbage disposal is full of food scraps. If you recently replace the garbage disposal with a new one, the technician will check to make sure the installer took out the knock-out plug for the dishwasher drain hose connection on the new garbage disposal. The tech will then check the entire drain path and test the drain pump, electronic control board and wiring to determine the cause of the drain problem and replace any failed parts.

Finding an inch of water at the bottom of your Bosch dishwasher typically signals clogged drains or a pump glitch. Letting it sit can lead to bacteria and unpleasant odors. Look into fix dishwasher near me for block removal or pump repairs. Proper drainage keeps your Bosch fresh and ready for the next load.
