What does the Miele F13 error code mean?
F13 indicates that the heating system in the Miele dishwasher has failed. The water is not reaching the required temperature. On Miele machines, this can be caused by the heating element, the NTC sensor, or a fault in the control relay on the PCB.
🔍 Symptoms
- Dishes not properly cleaned — grease remains on surfaces
- No warmth or steam detected mid-cycle
- Very poor drying performance
- Glassware with white residue
- Error appears approximately 20–30 minutes into a hot programme
How to fix the Miele F13 error code
- Confirm the fault mid-cycle by checking for heat/steam.

- Test the heating element for resistance.
- Inspect the control board for any visible faults.
- Replace the faulty component — Miele recommends using genuine Miele spare parts.
