What's Happening
The dishwasher can't drain because the drain filter is blocked. Food particles, grease, and calcium buildup restrict water flow through the filter system. This is one of the most common Bosch dishwasher errors and is almost always a maintenance issue.
How to Fix It
Remove the filter assembly at the bottom of the tub and clean thoroughly. Check the drain hose for kinks. Verify the garbage disposal connection is clear (knockout plug removed). Run a diagnostic test cycle after cleaning to confirm the error clears.
Frequently Asked Questions
What does E24 mean on a Bosch dishwasher?
E24 means the drain filter is blocked. Food debris and grease have accumulated to the point where water can't drain properly.
How do I clean a Bosch dishwasher filter?
Remove the filter assembly at the bottom of the tub (twist counterclockwise). Separate the parts and rinse under warm water. Use a brush for stubborn buildup. Clean monthly to prevent E24.
What's the difference between E24 and E25 on a Bosch dishwasher?
E24 is a blocked drain filter. E25 is a blocked drain pump or loose pump cover. Both are drainage errors but E24 is simpler to fix — just clean the filter.
