I have a twenty year old worcester combi boiler with pilot light failure. It relights following instructions and is fine for a week or so then problem arises again, only this time it won't relight at all. Please, any ideas before we get man to have a look?Thanks in anticipation.

i think the fan may be stuck. you will need to gain access to the internals of the boiler so a gas safe engineer will need to be employed to do it. if it is the fan, a simple squirt of lubricant will free it and give you anything from a week to a year of trouble free operation but! you will need to get a new fan. Fit a new one as soon as you can as they tend to go at the worst possible time if you dont

check the water pressure on the combi could be low or in the back of your manuel there is a fault finding guide which is very good and simple to follow .

Most of these boilers don"t have a permenant pilot light they have electronic ignition that lights the burner when you are calling for heat or hot water, is there enough water pressure in the boiler ( there is a small gauge on the bottom r/h side of the boiler the needle should be sitting at between 1 - 2 if not enough pressure the boiler won"t light )

The by pass pipe may be limed up. This apparently causes a reduced flow which will stop the heating side of the thing working. Call out Worcester Bosch engineer. It costs £210 including VAT and most parts and they almost guarantee to get it working.

replace pressure release valve

Not the best day for this to happen.

Check the system pressure and top up if necessary - but after that the best advice is to get the people who fitted it for you to come out and sort it - These Worcester combis usually have a 5 year parts warranty and with a boiler that's just a few weeks old, you oughyt to be able to get the labour for nothing as well. It would be a shame to throw those benefits away by tinkering yourself.

When it reaches between 1 and 1.5 bar, it is time to turn the white knob back to the right to close the valve. Be very careful not to over-tighten. 7) Turn the filling key to the left until the arrow lines up with the open padlock and remove the key.

35 cdi worcester combi about 3 years old,heating not working,hot water works fine.It's been serviced not long ago.Room stat turned up and trv's ,but boiler want fire up,there's power to the boiler and the room stat the built in time clock is switched to on, but still nothing. do you think it could be the diverter valve, when i got there it was flashing SE which mean's it needs a service,cleaned the heat exchanger and burner with the proper worceter brush etc then re set boiler with technical, they also said it could be the built in clock and told me to disconect it, and just use the heating stat to control it.It still want fire.
