Direct answer
On a supported Bosch dishwasher, E24 means the dishwasher is not draining properly. Clean the filter and verify the pump cover beneath it is secured. Then inspect the drain hose, air gap and disposal connection for restriction.
What this covers
- Bosch dishwashers displaying E24
- The code and product type exactly match the official source
- Customer-accessible checks before component replacement
What it does not cover
- ×A similar code on another manufacturer or appliance type
- ×Codes omitted from the exact model manual
- ×Internal wiring, sealed-panel or live-electrical repair
Confirm E24 on the exact model
ReversiblePhotograph the complete display, record the model tag and note the cycle stage. Similar-looking codes can mean different things on another product line.
Check the condition named by the code
ReversibleClean the filter and verify the pump cover beneath it is secured.
Correct the remaining user-serviceable cause
ReversibleInspect the drain hose, air gap and disposal connection for restriction.
Run one controlled verification
ReversibleRun the drain function and confirm the sump clears. A clear path with a repeat E24 can require drain-pump service.
