Help please.
Have a problem an Ideal LXFF 260 boiler not igniting. Thermostat on full, water and heating programmer on Have checked through the fault find flowchart and so far
fan is working OK (replaced about 18 months ago)
boiler thermostat set to maximum and mains switch on
Ignition electrode is sparking BUT pilot does not light
Pilot injector is clear
Therefore I assume that there is no gas reaching the pilot - what do I need to check next.
For info the gas valve is a Honeywell VR4601A/A1036

If you have 240vAC at GV1 on the pcb then it is a faulty gas valve.

RGI job only though to replace, especially on these as they can be a pain in the ar*e
Thanks Dave, I'll check voltage on PCB.

By the way - waht is RGI??

Or if your getting to 240 at pilot solenoid just change that ,no need to touch gas it just held on by a clip

Hi Dave

Just checked with multimeter and have 233V at GVI when the boiler is on and pilot igniter clicking away.

Assume it needs a new gas valve so I will have to call in my local friendly Corgi guy. - Any idea what a reasonable charge is for this type of work??

if you can change the pilot solenoid then 10 mins

if you need the whole valve then 90mins as said they are a pain in the backside

Solinoid maybe £20 Gas valve £100 perhaps??
Thanks for all the help, going to check pilot solenoid first then call out the local Corgi guy if gas valve needs changing.
