What Your Machine Is Actually Telling You
LF (Long Fill) means the CCU commanded a fill but the water level didn't rise fast enough. After 8 minutes of trying, the machine gives up and shows LF.
LF vs F20 (Whirlpool): Same concept, different naming.
Common causes:
1. Water taps closed (30%).
2. Inlet filter screens clogged (25%).
3. Kinked hoses (10%).
4. Low water pressure (10%).
5. Inlet valve failure (10%).
6. Pressure sensor (10%).
7. CCU (5%).
