Please tell me its complete model number
and how old is it ?
I don't know the full model number. I can only tell you it is about seven years old.
Does it make any different noise as well when the fault appears ?
It makes a bit of a whistling noise which wasn't there before.
First thing is to make sure the gas is on and available...if it is then it is ignition fault...will depend on many other things
The gas is on because it heats for up to a few seconds before it goes off again. There is something going on with the ignition because when you switch it on there are sparks visible around the ignition.
OK, when was it serviced ?
I'm not aware that it has been serviced in the time we've had it. It had the standard gas safety check.
the spark electrodes should be checked...basically it seems servicing the unit might solve this problem...will cost you around £100 approx. including repair...might work for few more years
That sounds a bit vague - what exactly do you mean by 'servicing'? Will any parts need to be changed and if so, which parts?
At times servicing the electrodes/valve solves the issue...if not then usually it is solved after replacing the gas valve.. I believe the Air/Gas Ratio problem, is the cause of the "whistling" noise that you hear
If the gas valve is also fine then the electrode will need replacement
I don't think any other parts can cause this issue
Will it require a specialist glow worm technician to carry out these checks and do a replacement or can a corgi man do it?
Well as gas valve is involved so I would recommend that this should be carried out by a specialist engineer
you can either contact the manufacturer or a local engineer
You can get back to me if you need any assistance and I will help with no additional charges....
OK, we will try by changing the electrodes first and if that doesn't work then we will look at the gas valve. Thank you for your help. I will get back to you then if I need to ask anything else.
