Door Lock Error

What Your Machine Is Actually Telling You
Fdl means the door lock assembly failed to lock after multiple retries (typically 6 attempts). This is more definitive than F22 — the CCU has given up trying.
Fdl vs F22:
- F22 = first failure to lock.
- Fdl = repeated failures, exhausted retries.
Fdl strongly points to hardware failure rather than a one-time issue.
Common causes:
1. Lock mechanism dead (40%) — PTC element failed permanently.
2. Switch contacts burned (20%) — can't confirm lock.
3. Wiring damage (15%) — broken wire.
4. Door strike worn (10%) — can't reach switch.
5. CCU relay (10%) — not powering lock.
6. Gasket interference (5%) — preventing closure.
