AWB fault code F32
Fault code F32 on an AWB boiler (including ThermoMaster) means: Air-side frost protection (fan speed deviation) Fan plug disconnected. Fan faulty. Wiring harness faulty. Main PCB faulty. Reset the appliance once. If the code comes back, a part is usually faulty. You can check the water pressure and settings yourself; leave work on gas-carrying parts to a certified gas engineer.
After a safety alert (gas, flue gas, combustion), reset no more than once and call in a certified gas engineer. If you smell gas, call your national gas emergency number or 112 immediately.
