Error codeE24
ApplianceDishwasher
Quick answer
E24 points to a drainage problem — the dishwasher is not draining as expected.
Model compatibility: Bertazzoni reuses codes across series and model years, so E24 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The E24 code indicates the dishwasher detected that water is not draining properly. It usually relates to a restriction in the drain path rather than a serious internal fault.
Signs
Symptoms you may notice
Water remains at the bottom after a cycle
E24 appears near the end of the cycle
Longer cycle times
Why it happens
Possible causes
A clogged filter or sump
A blocked or kinked drain hose
A restricted air gap or disposer connection
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Check and clean the accessible filter per your manual
Confirm the drain hose is not kinked where visible
If connected to a disposer, confirm the knockout plug was removed
Important safety warning. Standing water combined with electrical components means you should avoid deep disassembly. Basic filter cleaning is fine; internal drainage repairs are not.
Please avoid
What not to attempt
Do not disassemble the drain pump
Do not remove internal electrical parts
Do not force objects into the sump

When to call a technician
If cleaning the filter and checking the hose does not clear E24, book a diagnosis to inspect the drain pump and path.
