biasi 124mfs fault finding dhw ignition?
My old boiler is starting to play up. When running dhw the pump runs but ignition refuses to kick in. I then have to turn on the c/h ( which takes about 5/10 minutes to ignite) and only then does the dhw work okay. Water pressure is okay and have checked the manual fault finder page. Any ideas?? The wife is giving me grief!
