Heat Pump Error Codes
Error codes in Vaillant heat pumps can indicate various issues with the system. It's essential to consult the specific documentation provided by Vaillant for your heat pump model, as error codes can vary. Below are some common Vaillant error codes and their potential meanings:
F.00 or F.0:
This code often indicates a communication error between components.
F.10:
This may indicate a flow or circulation issue. Check if the pump is functioning correctly.
F.20:
This code is related to a water pressure sensor issue. Ensure that the water pressure is within the specified range.
F.22:
A code indicating low water pressure. Check the system pressure and repressurize if necessary.
F.49:
This may suggest a refrigerant pressure sensor fault. Professional assistance is recommended.
F.50:
A code related to an issue with the outdoor sensor. Check the sensor and its wiring.
F.61 or F.62:
These codes are associated with issues in the gas valve operation. A professional technician should investigate.
F.75:
This indicates a fault with the high-temperature sensor. Professional attention is needed.
F.77:
This code suggests a fault with the external temperature sensor.
F.79:
This code is related to a fault with the condensate pump.
It's important to note that interpreting error codes requires specific knowledge about your heat pump model. Always refer to the user manual or technical documentation provided by Vaillant for your specific heat pump. If you encounter an error code and are unsure about its meaning or how to address it, it's recommended to contact Vaillant's customer support or a qualified technician for assistance. Attempting to resolve complex issues without proper knowledge can lead to further problems.

Excellent and helpful instruction on the heat pump
I've just had my annual service with Adam (#237), and he has been excellent. He went above and beyond, calling in to check my remaining warranty and reviewing an earlier repair. Overall, an excellent and reassuring experience. He was courteous and highly professional, and tolerated all my questions about my boiler, Vaillant and heat pumps!
As part of my renewable energy project I was recommended a Vaillant heat pump by the installers. The weather has been very warm so no heating has been needed. My hot water is perfect. The heat pump is almost completely silent when operating. I am very pleased with the installation but can’t comment on the effectiveness of the heat pump until there is a serious cold spell in winter.
We had a Vaillant air source heat pump fitted to our new build house . The installers made a great job of it and we can't wait to move in and use it over the winter .
Pump needed to be replaced after 6 years, despite annual servicing and low usage. Attempt to make warranty claim (having purchased 7 year extended warranty) failed completely. Abysmal customer service, written complaint ignored. Never again!
