What to check first
Stop normal operation while this warning is active. Follow only the documented safe checks or protective-drain instructions for the exact model.
Basic checks
- Stop the program and leave the dishwasher off.
- Record the exact F24 code and dishwasher model before contacting service.
- Check only that the dishwasher is not visibly wet or damaged from outside.
- Let the appliance cool before any retry; if the code appears cold, the sensor warning is still active.
- Check for unusual heat or odor from outside the appliance; if present, stop use and keep power off.

FAQ
What does Miele Dishwasher code F24 usually mean?
Usually indicates a heating relay contact fault that Miele treats as a service-level technical fault. Model context matters: Miele's support page frames F24 as a technical heating-relay fault rather than an owner-level cleaning issue.
Can I keep using the dishwasher with code F24?
Stop normal operation until the issue and safety warnings have been addressed. Follow only the documented safe checks or protective-drain instructions for your model. Do not open panels or inspect electrical relay parts.
When should I call a technician for Miele F24?
Book Miele service if F24 appears. A qualified technician may check Heating relay, Heating circuit, and Control electronics against the model's service information before treating any part as failed.
