hi,I have a utility room attached to the side of the house which is of single brick, is there anything I can do to prevent damp and black spots appearing on the inside of the wall which is rendered,thanks for any advice. mike.

hi I have the above boiler,at the moment the boiler will not fire up,there is a flashing neon above the fan sign,is there anyone out there know what the problem might be, thanks, mike.

re the previous post, the boiler came on as per timer,led light showing heating,temperature led lights came on all the way up to 80 degrees (quite quickly) burner light goes out, I can only assume the pump doesn't kick in, I turn the hot water tap on, domestic hot water led is on. hot water...

I've just starting to have a problem with the above boiler,no hot water, I had the same problem 2/3 years ago it was the blending valve,could anyone tell me if there is any maintainance you can do on a blending valve,ie descale the inside for instance,if not it looks like another new one...

hi agile and 45yearsagasman,thanks for the info.followed your instructions on how to check EV pressure properly,it seems to have done the trick. thankyou.

hi I checked the EV by putting a pressure gauge on.

the above boiler when on central heating the pressure gauge goes above 3 bar, I have checked the filling loop,not letting by. checked the expansion vessel,pressure ok. has anyone any other suggestions. about 4 years ago I had the same problem,it turned out to be the plate heat exchanger...

thanks misterdubya,but what is a communication tube,I had a problem like this 4 years ago and it was the plate heat exchanger,

thanks for that reply namsag,checked pressure in expansion vessel,seems to have the correct pressure 0.5 bar,any other idea's,thanks

when I have this boiler on central heating,the pressure gauge goes up to over 3 bar,the pressure relief valve kicks in and discharges water through the pipe,can anyone tell me what the problem is? what is causing the pressure to rise?
