Hello
I have an 8yo old baxi duotec combi 24he boiler.
When the gas central heating is running, it makes a constant loud high pitched humming/whinning noise.
The noise only quietens for about 5 seconds, each time the boiler reignites to heat the radiator water. Before then returning to the same...

Hi there,
A customer has a Riva Compact HE (M96.24SM/C) combi. They are saying that the boiler fires for 10 to 15 seconds then goes to lock out. This happens on hot water and heating. They re-set the boiler then the same thing happens again.
Does anyone know what it may be? Possibly overheat...

My central heating system is well over 20 years old, but it's been working reasonably well until recently.
Firstly it seemed the 3 way value was getting stuck and sometimes there wasn't any heating. Switching CH/HW off and on seemed to fix, and so I replaced the Honeywell valve's head...

OMG, what a nightmare of a job.
The boiler DHW would cut off after about 30 seconds. Central heating was OK. The fault code was F20 and having a look at the manual, it was stating to be an overheating problem. Code F24 was also showing which was pointing to water circulation problem.

Hello,boiler ran out off oil and the fella has filled up tank. He asked me to bleed so I went down and got the oil to the burner. It fires for 30-60 seconds then cuts out with the red lift on boiler coming on. There is a flow to the burner but won't stay on. Would this be oil pump maybe? It's an...
Hi,
My boiler is about 7-8 years old.
My boiler CH works fine on its own as does the DHW.
