Common Vaillant Fault Codes

  1. Fault Code F22 – Low Water Pressure:

    • This is a prevalent fault code, often indicating a loss of pressure in your boiler system, which may be due to water loss. A pressure reading below 1.0 bar on the gauge is a sign that your boiler is at risk of shutting down. Frequent pressure loss may be caused by a system leak, a faulty pressure release valve (PRV), or a malfunctioning expansion vessel. The remedy is to use the filling loop to raise the pressure to 1.5 bar. If the F22 fault persists, it could be a faulty pressure gauge.
  2. Fault Code F75 – Pressure Issues:

    • This code typically points to a blocked pressure sensor. When the pressure sensor is obstructed, it can’t detect the pump’s operation, causing the boiler to miss pressure changes. If this issue persists, it may indicate a dirty system that requires a powerflush. Our gas-safe engineers can assist in resolving this problem.
  3. Fault Codes F27 & F28 – Condense:

    • A blocked condense pipe is the likely culprit here. This may occur if your condense pipe is undersized, frozen during cold months, or improperly installed with an uphill run. If the condense pipe is frozen, use warm water (not from the boiler) to thaw it, as boiler water can damage the pipe. If the issue persists, consider rerouting the blocked condense pipe. Unusual noises from your boiler, similar to a washing machine, could be a sign of this problem, and in such cases, it’s advisable to turn off the boiler to prevent potential flooding.
  4. Fault Code F62:

    • This code indicates a jammed-closed gas valve or a failure in the power supply to the gas valve. You’ll likely need a gas-safe engineer to address this issue.
  5. Fault Code F28 – Ignition Fault (TurboMax Range):

    • When your TurboMax Range boiler fails to ignite, it could be due to a faulty or worn ignition lead or a gas valve that is not opening properly. A potential issue with the PCB, which might not be sending power to the gas valve, should also be considered. It’s recommended to seek professional assistance to resolve this problem.
