HELP WITH MY TRIANCO COMBI 110 F.S OIL BOILER

[Hannah]

My problem is that for last 3 years my boiler keeps cutting out, but only in Winter when it is on the timer morning and night. Sometimes it will go off about 3 or 4 times in in a couple of hours and then becomes difficult to start on the reset button. Other times it will not reset for an hour or more and then it can go off again fairly quickly. It is serviced every year and I find the cost involved with getting an engineer out each time is quite prohibitive.

Does anyone else have this problem and more importantly have they resolved it. Any help out there would be so welcome as I am a retired pensioner.

I really want to be able to pass this information on to the Central Heating engineer who comes here in the hope it will save me some money

I suffered this problem, or more accurately my boiler did. What appears to have worked is a power flush to clean the system thoroughly.

Thank you for that information I will pass it on to the guy who does my repairs.

Lets clarify what is tripping an overheat thermostat or the flame failure detection on the burner?

Serviced every year by the same person/company? If so they ain't doing a very good job of it, our (admitedly an open flued, massive cast iron lump, non condensing system boiler) just works. The only times it has played up has been when the oil line froze (had dip that collected water) and when the flue had holes half way up and with the wind in the wrong direction would blow the flame out. It would reignite but this repeating lead to a build up of soot on the photocell and eventually a lock out.

Things to check, oil supply, there is some in the tank? Filters clean, not blocked, fire valve not blocked(*) or partially operated, flexable hoses not collapsed inside, the jet should be replaced each year, photocell cleaned, electrodes cleaned and positioned correctly.

(*) Clearing the frozen oil line dislodged a load a grunge that ended up blocking the fire valve. There was no filter at the tank outlet only after the fire valve...
