The Vaillant F22 Fault Code

How to Fix the F22 Vaillant Fault Code: A Comprehensive Guide

If you’ve come across the Vaillant F22 fault code on your combi boiler, you’re not alone.

This particular error often signals an issue with the water pressure in your heating system.

Fortunately, fixing the F22 Vaillant fault code is usually a simple task that most homeowners can do themselves.

In this blog post, we’ll explain how to identify the F22 error, what it means, and provide step-by-step instructions on how to fix it.

Plus, we’ll explain how we at WLV Heating, a professional heating company offering expert services for Vaillant boiler repairs and maintenance, along with their innovative new online booking tool can solve this common boiler problem.

What Does the F22 Vaillant Fault Code Mean?

The F22 fault code typically appears on Vaillant boilers when there is a lack of water pressure in the system.

When the pressure drops too low, the boiler can’t function correctly, which leads to the error code being displayed.

In general, Vaillant boilers operate most efficiently when the pressure is between 1 and 1.5 bars.

If the pressure falls below 1 bar, it may trigger the F22 error, which prevents the boiler from igniting or working effectively.

Common Causes of the F22 Vaillant Fault Code

  1. Low System Pressure
    The most common cause of the F22 fault code is low water pressure. This can happen due to leaks in the system, valve issues, or if the system has been recently drained.
  2. Leakage in the Heating System
    Small leaks in the radiators, pipes, or valves can cause gradual pressure loss. Even minor leaks can lead to the F22 error over time if not detected and repaired.
  3. Faulty Pressure Relief Valve
    If the pressure relief valve is malfunctioning, it may not be able to maintain the correct water pressure, leading to the appearance of the F22 code.
  4. Air Trapped in the System
    Air locks in the heating system can interfere with the water pressure, causing an imbalance that leads to a drop in pressure.
  5. Faulty Expansion Vessel
    The expansion vessel in your boiler helps regulate pressure changes. If it becomes faulty or waterlogged, it can result in low pressure, triggering the F22 fault.

How to Fix the F22 Vaillant Fault Code

Before calling a professional heating engineer, there are several steps you can take to try and resolve the F22 Vaillant fault code yourself.

Step 1: Check the Boiler Pressure

The first thing you need to do is check the water pressure gauge on the front of your boiler. This will typically display a dial or digital reading.

If the pressure is below 1 bar, you’ll need to repressurise the system.

Step 2: Repressurise the Boiler

If you’ve determined that the pressure is too low, follow these steps to repressurise your Vaillant boiler:

  1. Locate the filling loop: This is usually a small, flexible silver hose beneath the boiler with two valves.
  2. Open the valves: Gently open the valves on both sides of the filling loop. This will allow water from the mains supply to fill the system and increase the pressure.
  3. Watch the pressure gauge: As you open the valves, monitor the pressure gauge carefully. Once it reaches around 1.2 to 1.5 bars, close both valves tightly.
  4. Check for leaks: Ensure there are no leaks in the system around the filling loop or other visible pipework.
  5. Reset the Boiler: After repressurising, press the reset button on your Vaillant boiler to clear the F22 error.

Step 3: Bleed the Radiators

If your system is still showing the F22 code after repressurising, there may be air trapped in the radiators. To fix this, you need to bleed your radiators:

  1. Turn off the heating and allow the system to cool.
  2. Use a radiator key to slowly open the valve at the top of each radiator, releasing trapped air. You’ll hear a hissing sound when the air escapes.
  3. Once the water begins to flow steadily, close the valve and move on to the next radiator.
  4. After bleeding all radiators, check the water pressure again and repressurise if needed.

Step 4: Check for Leaks

Inspect your boiler and the entire heating system for visible leaks.

Check around the boiler, pipes, radiators, and valves for signs of water leakage.

If you find any leaks, you will need to call a professional to repair the damage.

Step 5: Contact a Professional

If the F22 fault code persists after these steps, the issue may be more complex, such as a faulty pressure relief valve or expansion vessel. In this case, it’s best to contact a qualified heating engineer for further diagnostics and repairs.
