Glow Worm Space Saver 40 MK II - Boiler Problems


Postby 111MATTHEW111 » Wed Apr 09, 2008 6:20 pm

Hello,

Recently my pilot light went out on my boiler.

It is a Glow Worm Space Saver 40 MK II.

I had a plumber round today and he went through the following steps to
get it firing again.

1. Replaced thermocouple. Checked it is working - works fine.
2. Cleaned out the gas supply to the pilot light - was slightly blocked - is
now clean as a whistle.

The pilot light now burns bright and strong. Yet still when uncompressing
the button for the pilot light - the pilot extinguishes.

Looking more closely, it appears that the contact where the thermocouple
meets the wire which carries the single to the gas valve to stay open
looks in bad shape. i.e not much metal on the metal contact due to
erosion.

We stripped the wire back slightly to make for a much better contact.
Attaching the thermocouple back up the problem still remains, the pilot
light goes out when the button is uncompressed.

Does this only leave the gas valve? Or is there something else to try?

* The pilot is clean and burning brightly.
* The pilot engages the thermocouple and heats it well.
* The thermocouple has been tested and works.
* The thermocouple engages the wiring which transports
the signal to the gas valve to remain open. (Although no electronically tested)

On the underside of the gas valve reads:

Gas Valve v8600a 1024 2
DIN DGVW 85.04c 050
CAT III Pmax 50 mbar

If it is the gas valve - where can I get one from?

Can I try anything else?

The plumber has left with the assumption that it must be the gas valve. I'd
rather have some expert opinion before handing over £150 to get a gas
valve fitted.

Thanks in advance

Matt
