Bosch Dishwasher Poor Drainage

Is your Bosch dishwasher not draining water? There are some common reasons this could be happening. If a Bosch dishwasher won’t drain completely, check the following to identify and fix the problem.

When you have a Bosch dishwasher not draining, you need to find out why. Try these troubleshooting tips to diagnose the problem.

Clogged Air Gap

Right now you may be wondering “Where is the air gap on my Bosch dishwasher?” You should know upfront that not all dishwashers have an air gap. If your model does have one, it’s usually a little cap of some sort on top of the sink. Unscrew or pop off the cover and clean it out!

Filter Is Obstructed

Do you have a dishwasher still full of water after the cycle is complete? A Bosch dishwasher not draining water can be as simple a fix as cleaning out a clogged filter. Remove the bottom rack to access the filter tube and remove it bu turning counter-clockwise and clear out any food and debris.

Drain Line Is Clogged

“Oh, NO! There is still water in my Bosch dishwasher!” Unnerving as this is, check the drain line that connects from the dishwasher to the sink or garbage disposal. This is a very common place for clogs to form. Remove the drain hose and clear it out. Clean out the fittings near the garbage disposal while the hose is disconnected to ensure there is no blockage.

Drain Pump Failure

Drain pumps force water through the drain hose. If the pump fails, the water won’t drain. Use a multimeter to check the drain pump for continuity. If there is no continuity, the part will have to be replaced as they cannot be repaired.
