E24: what does it mean and how to fix
What does it mean?
the dishwasher is not draining properly.
How to fix first
Switch off power before checking the filter area.
Why is this happening?
Blocked filter or sump area
When should I call an engineer?
Call a dishwasher engineer if the code returns after safe checks, water appears under the appliance, heating is affected, the pump is noisy or jammed, or diagnosis would require access inside the cabinet.
What does this error code mean?
Bosch dishwasher error code E24 usually means water is not leaving the dishwasher as expected. The most useful first checks are the filter, drain hose, sink spigot, and waste connection.
If the pump seems blocked or the fault changes to a pump obstruction warning, compare Bosch dishwasher E25. If debris is mainly in the filter area, see Bosch dishwasher E22.
E24 usually points to the drain path: filters, sump, hose, waste connection, and drain pump performance.
Symptoms users may notice
- Dirty water may remain in the base of the dishwasher.
- The programme may stop near the drain stage.
- The sink waste may gurgle or drain slowly at the same time.
Why is this happening?
- Blocked filter or sump area
- Kinked, trapped, or restricted drain hose
- Blocked sink spigot or waste connection
- Drain pump struggling under load
What this usually points to
E24 usually points to the drain path: filters, sump, hose, waste connection, and drain pump performance.
How to fix this safely
- Switch off power before checking the filter area.
- Remove and clean the accessible filter and check for glass, food debris, or labels.
- Check the drain hose and sink waste connection for kinks or blockages.
- Run one drain or short programme after refitting everything securely.
Can I fix this myself?
YesYou can carry out simple external checks such as filters, hoses, visible water, and correct loading. Stop when the fault points to internal pumps, heaters, wiring, or controls.
Safety boundary: Disconnect power before accessible checks. Do not remove panels, bypass safety devices, work on wiring, or run the dishwasher if water may be reaching electrical parts.
What not to do
- Do not keep repeating resets if the same code comes back.
- Do not remove panels or work on internal wiring, pumps, valves, or heater parts.
- Do not ignore leaks, burning smells, or unusual pump noises.
Reset steps
- Restore power only after the safe external checks are complete and the area is dry.
- Run one short test programme if there is no visible leak, smell, or electrical concern.
- Stop if the code returns or the dishwasher fails to fill, heat, drain, or wash normally.
Intermittent vs persistent faults
A one-off warning may clear after safe external checks, but repeated Bosch dishwasher faults should be treated as a persistent problem that needs diagnosis.
When to call an engineer
Call a dishwasher engineer if the code returns after safe checks, water appears under the appliance, heating is affected, the pump is noisy or jammed, or diagnosis would require access inside the cabinet.
Safety warning
Disconnect the dishwasher from power before checking accessible filters, hoses, or seals, and do not remove panels or work on internal electrical, pump, heater, or valve parts yourself.
