Bosch Dishwasher Error E24 — Drain Fix

What Does This Error Mean?

Error E24 means the dishwasher cannot drain. Check and clean the filter, inspect the drain hose for kinks, and make sure the sink drain is not blocked.

How to Fix It

Remove the bottom rack and take out the filter assembly. Rinse it under hot water using a brush to clear grease and food debris.
Check the drain hose at the back of the machine. Ensure it is not kinked, squashed, or bent sharply — straighten if needed.
Check where the drain hose connects to the sink or waste pipe. Clear any blockage in the sink trap or waste pipe connection.
Make sure the drain hose is looped to the correct height (50-60 cm from the floor) to prevent backflow. Check your manual for the exact requirement.
Run a short cycle. If E24 persists, the drain pump may be blocked or failing — a technician will need to inspect it.

Frequently Asked Questions

What is the difference between E24 and E25?

E24 usually points to a drain blockage in the filter, hose, or waste connection. E25 specifically means the drain pump impeller is jammed or the pump has failed.

Can I manually drain the dishwasher when E24 shows?

Yes. Remove the filter and use a sponge or turkey baster to remove standing water from the bottom of the tub before investigating the blockage.

How often should I clean the Bosch dishwasher filter?

Clean the filter once a month under normal use. If you notice slow draining or odours before that, clean it sooner.
