Atlantic fault code 63
Fault code 63 on an Atlantic heat pump (including ODU Monoblock Atlantic 11 and ODU Monoblock Atlantic 6) means: Inverter fault. Reset the appliance once. If the code comes back, a part is usually faulty, often the compressor or inverter module. 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.
