The G 1220 series typically signals faults via indicator lights or alphanumeric codes on the display: F11 (Drainage Fault):
Indicates water is not draining. Check for a blocked filter, kinked drain hose, or a jammed non-return valve in the sump. F12/F13 (Intake Fault):
Water is not entering correctly. Inspect the stopcock, the water inlet filter (at the hose connection), or a defective inlet valve. F14 (Heater Pressure Switch):
Often caused by insufficient water pressure or a faulty switch that regulates water levels during heating. F70 (Float Switch):
Water has leaked into the drip pan (base). This triggers the anti-flood system and requires checking for internal leaks. 3. Access & Disassembly
