The Vaillant Boiler F22 error indicates low water pressure. Restoring the pressure usually resolves this issue and allows your boiler to function properly again.
Understand the F22 Error Code
The F22 error code on a Vaillant boiler typically signals that the water pressure is too low for the system to operate efficiently. This can occur due to a leak in the system, bleeding radiators, or simply because the boiler has been drained for maintenance. Recognizing the symptoms early can prevent further complications and ensure your heating system remains functional.
| Symptom | Primary Suspect | Difficulty (1-5) |
|---|---|---|
| F22 Error Code | Low Water Pressure | 2 |
| No Heat | Air in System | 3 |
| Boiler Noise | Leak or Blockage | 4 |

Vaillant Boiler F22 Pressure Restoration Steps
If your Vaillant boiler is displaying the F22 error code, it typically indicates low water pressure, which can disrupt heating and hot water supply. Understanding how to restore the pressure is essential for maintaining your boiler’s efficiency and functionality. The following steps will guide you through the process of resolving this issue effectively.
Follow these steps to restore the water pressure in your Vaillant boiler. Each step is crucial to ensure a successful fix.
Locate the Filling Loop
Find the filling loop, usually located beneath the boiler. This is a flexible hose with two valves.Open the Valves
Use the adjustable wrench to open both valves on the filling loop. This allows water to flow into the system.Monitor the Pressure Gauge
Watch the pressure gauge as you fill the system. Aim for a pressure reading between 1.0 and 1.5 bar.Close the Valves
Once the desired pressure is reached, close both valves securely to prevent water loss.Check for Leaks
Inspect the filling loop and surrounding areas for any signs of leaks. Tighten any loose fittings as necessary.Turn On the Boiler
Restore power to the boiler and check if the F22 error code has cleared. If the boiler operates normally, the problem is resolved.
