Haier fault code F12
Fault code F12 on an Haier air conditioner (including Expert and Jade) means: Outdoor unit EEPROM (PCB) defective. Reset the appliance once. If the code comes back, a part is usually faulty, often the burner control unit or PCB. 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.
