My Valliant turbomax plus 837 combination boiler recently stopped giving hot water. We had to replace the fan.

Now whenever we try to use the hot water there is a red light on the boiler and shows number F29 on the display.

What does this mean and how can I correct this problem.

Hi

F29 is the fault code for a flame failure. You will need to contact a CORGI registered installer to repair the fault for you.
