HELP !!! we are the proud(?) owners of a potterton profile prima 60e boiler from the stoneage that does some strange things.
Quite often when starting from cold, the fan will start and stop every few seconds without the boiler having a chance to fire up. sometimes the fan will stay on after a minute or so of doing the on/off thing, and the boiler lights and works o.k, but often it takes a lot longer and sometimes doesn't come on at all. the only way to get it to work is by giving he boiler a firm knock or sliding the levers on the wall programmer up to off then back to on 2or3 times. occasionally, we find the same thing happening even after the boiler has been on for an hour or two.
we had the fan replaced a year ago and the system was powerflushed just before that.
Please help, as it drives us insane and i'm going to have to kill it soon....
