Vaillant fault code F.583
Fault code F.583 on a Vaillant heat pump (including geoTHERM 3 kW) means: Four-way valve is mechanically blocked, temperature sensor in the flow is defective, air in the emitter circuit. Reset the appliance once. If the code comes back, a part is usually faulty, often a temperature sensor. 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.
