Glowworm spacesaver MK2 - wont fire

[dave-dell]

Hi Guys

Can you help us please. Boiler refuses to fire up this morning. Pilot is lit and i can hear the pump running. I took the silver screw from the pump and the inner bit is turning.

Anyone know whats the matter - we're freezing at the moment.

Many thanks

Dave

would suspect blr stat or gas valve

 

[dave-dell]

What is a bir stat ??

 

[twgas]

thermostat on boiler

 

[dave-dell]

I'm an electrical engineer.

Can i test the stat and gas valve. What do i need to look for on both especially the gas valve

 

[gas4you]

240V ac at the gas valve terminals. If it is there its the valve stuck.

 

[bengasman]

is it a flue fanned model, if so, check that aps makes

 

[dave-dell]

Thanks gas4you. Got 240v at the gas valve terminals. So looks like its gotta be the gas valve. Hoping it wasnt as this is a gas valve that is only 18months old.

When you say 'stuck' does this mean a new one is needed or could it be 'unstuck' ??

Bengasman: Its a balanced flue so no fan - well i cant see one anywhere-

Also the stat was mentioned in a previous reply. Could this be at fault. Could i test its working with my meter?

Thanks

Dave

it is SOMETIMES possiblle to get a valve back into live but it is not something i would recommend doing unless it is a last resort and you really know the ins ant outs of gasvalves.
nor would i recommend changing the valve yourself as it is an essential gaspart that needs setting and testing

 

[twgas]

the thermostat must be working to supply 240v to gas valve

 

[gas4you]

Don't know if these valves can have just the solenoid replaced, but again corgi territory.

CORGI guy coming out to fix it tomorrow afternoon
