Washer
Code C1
high severity
Miele models: Miele washers have a fine lint filter and a separate drain pump cover, accessed via the lower-front service flap. Miele's EcoTechnology motor is rated for 20 years — repeated faults on a relatively new Miele warrant professional attention rather than DIY. Miele recommends UltraPhase 1+2 liquid detergents; powder tablets can reduce filter life.
Common causes
- Motor temperature protection tripped
- Control board detected an unexpected sensor combination
- Power interruption during a sensitive part of the cycle
Step-by-step fix
- Unplug the machine for 10 minutes to allow full reset.
- Restart with a small test load.
- Check that inlet, drain, and door are all normal before retrying.
Tools you may need
None
Prevention
- Do not interrupt cycles by cutting power at the wall mid-programme.
- Use a surge protector.
When to stop DIY
Call a technician if the lockout recurs across multiple cycle attempts — a sensor or control board fault is preventing normal operation.
