Puma 80 Boiler Heating Troubles

[Rustygoat]

Hi Everyone and apologies if this has been dealt with in the past. I have searched but can't find anything relevant.
Problem....daughter's Puma 80 combi boiler. It's been in the house before she moved in about 6 years ago and has generally been OK. (Leak on the pressure relief valve - replaced)
Hot water is fine.
Central Heating - occasionally pilot light goes out and of course no heating. It relights OK - new piezo igniter fitted. The pilot light is absolutely fine if left on hot water and works for days - but on heating it's unreliable.
CH pressure is just over 1 bar cold, the low pressure light is not lit.
Any ideas for me to check? Thanks.
PS She can't afford a new boiler!

sorry mate but advising untrained people to play with boilers is trouble and will invariably invalidate your daughters house insurance

Has it had a proper service in them six years?

As said above,probably a service required by a gas safe plumber,am sure you want to keep your daughter safe,with particular attention to the pilot jet that has to be nice and clean or will keep going out as described,also have fan lubricated during service

imho

Thanks for the replies. I wasn't planning on playing with the gas bits. Can anyone explain why the pilot light is OK on hot water and not on heating? It's a permanent (well almost) pilot light.

you have allready had a play with the boiler and no one is naive enough to think you wont continue having a dabble as stated get a trained engineer

All I have done is look through the window and try and work out what is happening before GSI. It's always useful to have some idea before doing that. Unfortunately "her guy" has retired (and moved away) and she has to find a new gas fitter/plumber that is reliable, knowledgeable etc.

These types of appliance were desingned to be serviced every 12 months other wise things get to a point and dont work properly.
There is nowt u can do to it legally that is likly to sort it out,get it serviced!
