Bosch dishwashers are energy efficient and have many different features, including a triple-filtration system, sanitising option, noise reduction, variable spray pressure and a load-size sensor. While most Bosch dishwashers work well with maintenance and care, issues can arise, including the dishwasher failing to drain properly. If this happens, try some troubleshooting to fix the problem.
Unplug the Bosch dishwasher. Examine the filter system, located in the bottom of the tub, for large objects that may be blocking the filter. Unscrew the spray arm, lift out the filter and clean the filter with water.
Scoop out any standing water that is in the dishwasher.
Lift up the edge of the pump cover with the rounded edge of a spoon until it clicks. Grab the lug and pull the cover up and out. Look inside for any objects or blockages and clean as necessary. Set the cover back into position and push into place. Set the filters back into place, followed by the spray arm.
Examine the drain hose and straighten if kinked. Clean, if necessary, to remove possible obstructions.
Restore power and set the washer to "Drain" and select "Start." Contact a Bosch service centre if the above steps do not fix the problem.
