Bosch Dishwasher Error Code Not draining

This error means the dishwasher was unable to fully drain water from the tub within a 5-minute cycle window. The control board monitors the drain process and stops operation when it detects that water has not been evacuated in time. This protects the motor and prevents overflow. The issue is almost always related to a blockage, hose restriction, or pump failure.

You should not continue running the dishwasher until the drain issue is resolved. Standing water left in the tub can become unsanitary and may damage internal components if cycles are forced to run. Running the appliance repeatedly while it cannot drain can also overstress the drain pump motor. Address the root cause before resuming normal use.

If the fix is a simple filter cleaning or hose adjustment, there is no parts cost involved. Replacing a drain pump typically costs between $50 and $150 for the part alone, with professional labor adding $100 to $250 depending on your location and the service provider. Control board replacement, if required, is generally the most expensive repair, often ranging from $150 to $400 or more for parts and labor.

Start by removing and cleaning the sump filter at the bottom of the tub, as clogged filters are the most common cause. Next, check the drain hose for kinks and confirm the connection at the garbage disposal or sink drain is clear and unobstructed. If those components check out, test the drain pump for power and mechanical operation. A failed pump will need to be replaced to restore normal draining.

A reset may clear the error code from the display temporarily, but it will not resolve the underlying cause. If the drainage path is still blocked or the pump is still faulty, the error will return as soon as the next drain cycle runs. Clearing the code without fixing the problem is not a lasting solution and could mask a worsening condition.
