A drain pump is a handy little device that pumps the water from your dishwasher down the nearest drain.

If you notice any complications when pumping the water out of your dishwasher, you’ll know to replace it as soon as possible to avoid more problems with this important component.

This blog post will discuss how we can perform a drain pump test on a Bosch dishwasher.

Step 1: Turn Off the Power Breaker

Disconnect your dishwasher or turn off the breaker that powers it. This can be found in your electrical panel, but we recommend calling a professional if you don’t know where it is.

Also, remember to turn off your stove and disconnect other appliances on the same circuit as the one powering the dishwasher.

Step 2: Remove the Filter

Remove the Filter

If your Bosch dishwasher is not draining, check for debris or other clogs in the pump area. Use an old toothbrush to remove stubborn food particles if needed.

Suppose none are found clean and replace the water filter with a fresh one. A new water filter will solidify those particles and prevent future failures.

Step 3: Testing the Drain Pump

Follow these simple steps to see if the drain pump is working: Begin by removing the float from your dishwasher. The float is situated near the spray arm’s bottom.

If you’re having difficulties finding it, consult the dishwasher’s user handbook for assistance. A drainage pump may drain water from your device’s tub if you lift on the float.

If your gadget drains water from its tub within this period, your drainage pump is working properly, and your system’s pipes are clear.


Why does my dishwasher have standing water in the bottom?

Water at the bottom of a dishwasher can come from various places, depending on the dishwasher’s design.

Clogs in any system element, such as the filter, garbage disposal, or drain hose, can cause water to emerge at the bottom of your dishwasher.

Impurities in your water supply, especially from excessively chlorinated water, can cause problems by depositing minerals in various areas of these systems, clogging them.

Regular maintenance can sometimes fix slow drainage difficulties, but you may need to take further steps to unclog a blockage to ensure that your dishwasher drains properly.

How do I know if my Bosch dishwasher drain pump is bad?

Drain pumps force water through the hose and into the tub. If a drain pump fails, it can’t push the water down the drain.

Use your multimeter to measure the electrical resistance across the terminals on a failing drain pump. If there is no continuity, the part will need to be replaced because it cannot be repaired.


A drain pump test such as this will save your team time and frustration by ruling out drainage system issues that might otherwise get overlooked during troubleshooting. Consider trying it out the next time you have to deal with problems associated with your plumbing, sump pumps, or sink drainage systems.
