Service-safe actions
- 1No model-independent drain-pump repair is published for this code

Repair planning
E23 cost planning: €0 for an accessible blockage check; typically €10–€45 for a confirmed hose, cap, or seal. A diagnosed pump repair commonly moves into the €90–€220 service range before parts.
E23 time plan: 15–35 minutes to drain safely, inspect accessible points, refit them, and run one short drain test.
Dry towels, shallow tray, and household gloves, Flashlight, A coin or hand grip only if the exact-model manual permits opening the user-accessible filter cover
E23 parts decision: Usually none for clearing an accessible filter or hose. A drain pump is not confirmed by E23; match any pump, cover, seal, or hose to the full model only after diagnosis.
What not to do
- Do not force a jammed pump cover, tip an appliance containing water, or reach into the pump area while power is connected
- Do not electrically test the pump
- Do not remove the pump or fixed panels
- Do not run repeated drain cycles with standing water
- Do not run an extra test cycle after the source tells you to stop or arrange service for E23
Preventive maintenance
- 1Keep user-accessible filters, seals, hoses, and drain connections clean and inspect them periodically for damage or seepage
- 2Clean the filter regularly to reduce debris reaching the drain area
- 3If E23 begins recurring despite the documented maintenance, stop repeating the same action and request exact-model diagnosis
