Code F2
low severity
Miele models: Miele dishwashers use a three-stage filter system — clean all three parts together every 4–6 weeks. Miele strongly recommends Miele UltraTabs; generic tablets can leave a residue on sensors that triggers false spray-performance codes.
Common causes
- Inlet valve failing to close fully — machine slowly overfills
- Water level sensor (pressure switch) fault
- Blocked drain causing water to back up
Step-by-step fix
- Cancel the cycle and check whether the machine is full of water.
- If overfull, check the drain first — a blocked drain can cause apparent overflow.
- If the drain is clear, the inlet valve may be failing to close — test by unplugging: if water continues to trickle in, the valve has failed.
