Code C1
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
- Combined fault condition — typically a secondary error that the machine couldn't recover from automatically
- Power interruption mid-cycle
Step-by-step fix
- Cancel the cycle, unplug for 5 minutes, and restart.
- If a separate error code appeared before C1, address that code first.
Tools you may need

Prevention

When to stop DIY
Call a technician if the lockout recurs without another code being shown.
