What Does Error Code F24 Mean on a Miele Dishwasher?

Heating circuit fault — heater relay or temperature sensor.

F24 fires when the control monitors the wash cycle and finds the water is not reaching the target temperature within the expected time, or the temperature feedback is implausible. The board watches the NTC sensor while energizing the heating circuit; if the sensor reading, heater relay switching, or element continuity does not match expectations, it halts with F24. This differentiates it from related sensor-only faults like F14/F15, since F24 specifically flags the heating loop as a whole not responding.

Models affected: Miele dishwashers with a flow-through heating system, including the G 7000 Series and comparable earlier generations
What owners report: Owners commonly report F24 mid-cycle or when dishes come out cold and glassware isn't drying, since without heat the final rinse stays lukewarm. It can occasionally be a false alarm cleared by a power cycle, but a repeat code usually points to a genuine sensor, relay, or element fault rather than a fluke.

Frequently Asked Questions

Can I keep using my Miele Dishwasher when error F24 appears? +
It is not advisable. The dishwasher may still power on, but running it while F24 is active can worsen the heating fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes F24 on a Miele Dishwasher? +
Across reported Miele dishwasher repairs, the most frequent is heater relay on board failed (40% of cases), nTC temperature sensor fault (30%), then heating element failure (30%). Check them in that order before replacing any parts.
F24 keeps coming back after a reset — what should I check next? +
A reset only clears the stored F24 fault; if it returns, the heating problem is still present. Move on to the physical checks — test the NTC sensor, then test the heating element — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Miele Dishwasher error F24? +
A DIY repair typically runs $25–$130 in parts, versus $250–$500 for a professional service call, so handling it yourself saves around $225. Expect the work to take roughly 30–60 minutes.
Which Miele Dishwasher models show error F24? +
F24 is documented on Miele dishwashers with a flow-through heating system, including the G 7000 Series and comparable earlier generations. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
