Run one drain attempt
Listen for the pump and note whether any water moves.
Inspect the drain hose
Straighten kinks and check the sink or standpipe connection.

Disconnect power and prepare for retained water.
Stop before pump or wiring work
Internal pump and control diagnosis requires service.
What happens when E24 appears?
A blockage, jam, or restricted hose is likely.
The pump, wiring, control, or interlock may need diagnosis.
Check the filter, hose, sink connection, and installation height.

Official support and model manuals
Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.
Frequently asked questions
What does E24 mean on a Bosch dishwasher?
On many model families, E24 indicates that the dishwasher cannot drain. Confirm the exact model and region because the same display can be used differently.
Can I clear E24 by unplugging the dishwasher?
A short power reset may clear a temporary state, but it will not fix a blocked hose, leak, failed sensor, motor, heater, or wiring fault. Stop if the code returns.
Should I replace a part based only on the code?
No. A code identifies a system or condition, not always the failed component. Complete safe external checks and use the model-specific manual or qualified service.
