Profile 100e

[HarrogateGas]

Capped off a Profile today due to explosive ignition. BG have been out to it, its had a new Gas valve , new PBC and new pilot assy, The pressures are bang on. Cust lost rag with BG and called me. Im suspecting the new gas valve thats een fitted s knackeded. Anyone had this before on this boiler??

Its usually either the inner flue corroded or the white wire on the wiring set from the board to the gas valve .

the white wire on the wiring set from the board to the gas valve .

Eh? I assume you mean the main opens when pilot not lit?

Certainly do chris, it's where the white wire breaks down or has a path to earth. Usually condensation rotting through the inner flue causes explosive ignition on these though. FGA will pick that up straight away.

Its neither of the two things you mention....its has a new flue assy 1 year ago, once lit its readings are .0008. It you pull a wire off the pilot solenoid to stop the pilot lighting, no gas comes through.


Im going ith a PCB and gas valve today so ill let you know.

Different part of the gas valve (solenoid) but had to change a WRodgers one on a Profile yesterday which was less than a year old!

Nobody's interfered with the little brass air restrictor have they - could lead to ignition before fan up to speed?

had a profile 80 lpg with explosive ignition as you say the pressures were spot on boiler has been serviced correctly since installation 10 years.it never suffered the ignition problem while i was there but i noticed the gas valve was a bit noisey with a hum and rattle so duly replaced complete valve been as quiet as a mouse ever since

Believe it or not the APS was knackered.....long story. Flames not longer shooting 3 feet out the flue now anyway!!
