Apollo 50si

[Munier]

Can someone help.

I have an apollo 50 si boiler. the PCB and electrode lead have been changed twice over 6 months. The pilot is playing up again. It shuts off after about 5 minutes. When the PCB and electrode were changed in Feb 09 it has been working until now.

What could be the problem ?

Thanks to those who responded. What is an RGI and why is it that system was working until now.

Who decided the PCB needed changing twice in 6 months?

Might be worth getting someone in to look at it who knows what they are doing!

The problem is probably a gas-related issue which would need an RGI.

Some faults are harder to correct than others, but the boilers I can think of will keep the pilot on even if you rip the entire pcb out.
A bit more (precise) info about boiler, problem and such would not go amiss.

When the pilot drops out check the pilot solenoid on the gas valve for 240v if it there then its a faulty solenoid. easily changed.

The unit is an apollo 50SI. PCB has been changed twice. Pilot light comes on and then ignition switches off but is trying to ignite. the ignition is clicking but burners not coming on as burner is on but not firing up completely.

Does that help me ?
