Safety first
Stop and check this first
- Disconnect power and stop if water is leaking or has reached electrical parts.
Safe checks you can perform
- Inspect the visible drain hose
- Clean the filter and accessible pump area only when supported
Leave these tasks to a qualified professional
- Do not attempt this professional task: Clear an inaccessible drainage fault
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Clear an inaccessible drainage fault
What they doA qualified technician should inspect the pump and internal drainage path when accessible checks do not resolve E24.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Inspect the visible drain hose
Switch off power and inspect the accessible hose for sharp bends or visible residue. Do not pull out a built-in appliance unless you can do so safely.
Stop if water or wiring is exposed.

Clean the filter and accessible pump area only when supported
Disconnect power. Follow the owner manual for the exact model to remove and clean the filter, remove standing water and accessible loose debris, then refit the pump cover until it locks.
Broken glass or sharp debris may be present. Stop if the model layout differs or internal disassembly would be required.
