Vaillant boilers have a range of error codes associated with specific problems when things go wrong. As different problems can result in different symptoms, it’s possible that some will result in problems heating water, whereas others will result in radiators remaining cold when the house is cold. By using these codes, engineers can quickly diagnose faults, as they give clues as to where the problems lie.
Vaillant Boiler Problems
While there are a wide range of control panels on different models of the company’s boiler range, they all have a range of error codes designed to help you get an indication of the problem when you need to contact an engineer for repairs. Below, we’ve got links to all common error codes, which will flash up on the boiler’s display panel. On the image, you can see that just above the green light, but your model may differ slightly. All that’s important is the error code itself, which you can provide when booking an engineer visit.
