What Your Machine Is Actually Telling You
F13 means the CCU can't communicate with or control the automatic detergent dispenser motor. The dispenser uses a small motor to release detergent, bleach, or fabric softener at the right time.
Common causes:
1. Dispenser clogged (30%) — dried detergent blocking mechanism.
2. Dispenser motor (25%) — motor dead or burned.
3. Wiring (20%) — connector loose.
4. CCU circuit (15%) — dispenser driver failed.
5. Dispenser switch (10%) — position sensor fault.
