Bosch Dishwasher E24 Error Code

Meaning: The dishwasher cannot drain properly. The drain filter or drain pump area is blocked, or the drain pump cover is not seated correctly.

Risk: Medium. Standing water in the dishwasher is not an immediate safety hazard, but do not keep running cycles — the water will not drain and could overflow.

First safe checks:

Cancel the current cycle and open the door (carefully — there may be standing water).
Remove the bottom rack and locate the drain filter assembly at the bottom of the tub.
Remove the filter and clean it thoroughly under running water.

Call a technician if:

The drain pump makes no sound at all during the drain cycle.
The pump hums but water does not drain (jammed impeller — do not force).
E24 returns after cleaning the filter, pump cover, and drain hose.

Common causes

Clogged drain filter (food particles, grease)
Loose or missing drain pump cover
Debris (glass, bones, seeds) in the drain pump
Kinked or blocked drain hose
Calcium or grease buildup in drain path

Can you reset it?

Yes, with conditions. Clearing the blockage usually resolves E24 without a power reset. If the code persists after cleaning the filter and pump cover, there may be a deeper drain or pump issue.

Safe checks before calling a technician

Cancel the current cycle and open the door (carefully — there may be standing water).
Remove the bottom rack and locate the drain filter assembly at the bottom of the tub.
Remove the filter and clean it thoroughly under running water.
Check the drain pump cover beneath the filter — it should be firmly seated and not loose.
Remove any visible debris (glass, food particles, bones) from the pump area.
Check the drain hose under the sink for kinks or blockages.
Run a rinse cycle to test.

When to call a technician

The drain pump makes no sound at all during the drain cycle.
The pump hums but water does not drain (jammed impeller — do not force).
E24 returns after cleaning the filter, pump cover, and drain hose.
You see broken glass or hard debris inside the pump housing that you cannot safely remove.

How do I fix Bosch dishwasher E24?

Remove and clean the drain filter, check the pump cover is seated, inspect the drain hose for kinks, and remove any debris from the pump area.
