Product Information

If you have a problem with your Vaillant boiler, the chances are that one of the four issues we have detailed in this guide are to blame.

Many of our customers have experienced their Vaillant ecoTEC boilers playing up with intermittent F.75 issues, due to Water Pressure Sensor failures over the years. Fault code F.92 indicates a coding resistance fault. This occurs when the coding resistance on the PCB does not match the entered gas group. How to fix Vaillant Boiler fault code F.92 The F63 error code will be linked to the PCB, which will require an engineer to use a multi-meter to determine the exact cause of the issue.Fault code F.84 indicates implausible values detected by the flow and return temperature sensors. This can occur when the sensors have been inverted or incorrectly installed. How to fix Vaillant Boiler fault code F.84 This fault code is most common on the Valliant Ecotec Plus and Ecotec Pro models, and especially the Vaillant Ecotec Pro 28.

Fault code F.01 indicates an interruption in the return sensor. This could be caused by the NTC plug not being plugged in or coming loose, incorrect connection of multiple plugs on the PCB, interruption in the cable harness, or a defective NTC sensor. How to fix Vaillant Boiler fault code F.01 Vaillant boiler repairs can be the result of a number of different issues. The table below describes the most common reasons for a breakdown and whether or not you will need to call out a Homecure engineer. You can bleed the radiators with a key – if this doesn’t fix the issue, or you aren’t comfortable doing it, call our team. Ideally, you’d want your boiler to be operating at around 1-1.5 bar. In most cases, your boiler is leaking water if the pressure drops below 1 bar. What’s next? Still need help or have questions about your boilers? Fault code F.72 indicates a temperature difference that is too great between the flow and return sensors. This can be an indication of a defective flow or return temperature sensor. How to fix Vaillant Boiler fault code F.72

Possible causes– incorrect flame detection and the F27 fault code should not be ignored as it indicates an issue with your boiler’s delicate electrical components, particularly the brains of your boiler, the printed circuit board, or PCB. The fault could be caused by moisture building up on the circuitry or other electrical parts or worn-out ignition leads which will need to be replaced. After the F.75 code disappears from the display and four short separated buzzing noises are heard as the boiler is going through the pre-firing up procedure, there may be an opportunity to glean whether it is the boiler’s Water Pressure Sensor, or the Pump, that is the responsible part for the F.75 fault. See below our Vaillant fault code list to help you diagnose any issues with your Vaillant boilers. F.00 The first instinct most people have when there is a problem with their boiler is to call out an engineer. Sometimes this is needed, but there are times when you can fix the issue quite simply yourself.
