What E24 means
Error E24 indicates that the appliance has detected a problem draining water, usually caused by a blocked filter, pump or drain hose.
Common causes
- Clogged filter or sump area
- Blocked drain hose or sink connection
- Kinked or crushed drain hose behind the appliance
- Foreign object stuck in the drain pump
Quick checks you can do yourself
- Switch off the appliance and unplug it.
- Remove the bottom basket and take out the filter assembly; rinse it under warm water.
- Check the sump area for food, glass or other debris.
- Inspect the drain hose at the back and under the sink for kinks or blockages.
- Run a rinse program to confirm the dishwasher now drains correctly.
Always unplug the appliance and switch off power at the mains before removing panels or working near wiring or water connections.
When to call a professional
If you hear the drain pump running but no water leaves the machine, or the error returns after cleaning, the pump or control board may need professional diagnosis.
Recommended next steps
Cleaning filters once a week and scraping plates before loading will greatly reduce the chance of E24 returning.
Typical repair cost
£0–£130. Most E24 faults are caused by blockages you can clear for free. A replacement drain pump is often £60–£130 supplied and fitted.
How to prevent this error in future
- Rinse or scrape plates to remove large food scraps before loading.
- Clean the filter and sump area weekly to prevent grease and debris buildup.
- Check that the drain hose runs smoothly uphill to the sink trap without sharp kinks.
- Avoid very long or badly routed extension hoses that make draining harder.
