Bosch Dishwasher E24 Error Code
Drain filter blocked or pump cover loose
What this error means
E24 displays when water remains in the tub after the drain pump runs—Bosch's most common owner-fixable code. The drain filter, loose pump cover, or blocked hose prevents water from falling below the level sensor.
Common causes
- Cylindrical filter clogged with food paste and glass grit
- Pump cover under the filter not clicked fully into place
- Garbage disposal knockout plug still blocking the drain port on new installs
- Drain hose sagging below the sink trap without a high loop
Step-by-step fixes
- 1Remove the lower rack and twist out the filter assembly—rinse all sections under hot tap water
- 2Lift the pump cover with a spoon handle until it clicks down—Bosch manuals show the pry point
- 3Confirm the drain hose loops up to the underside of the counter before dropping to the disposal
- 4Run Cancel/Drain and listen for pump hum with falling water level
When to call a technician
E24 with a clean filter and verified hose often means a failed drain pump or jammed check valve requiring tub removal.
