My local guy called it right. Problem fixed with a new control box. All working well now.......until the next prob crops up!

Hi, Was this problem ever identified and cured? I am having the same problem with the same boiler - huge bang (sounds like a car back-firing if you are outside the house) every time the burner tries to light. Locks out after five attempts, by design. Switching of and on again, it will...

Tony, Again, thanks for the quick response and advice. Sorry for sounding thick, but I'm not sure how to circulate the CH water COLD to the rads. I think this Powermax bu**er has a seperate pump for the central heating, controlled by the thermostat. If the stat doesn't click (usually at...

Thanks Tony. I still have two rads to fix, both of which only get lukewarm. I'm sure the trusty 'wire up the pipe' might clear out the guff - this is how I cleared the other blockages. For a final clean out before I add the inhibitor, I've been reading about Sentinel Deposit remover. The...

It has taken some time, but between the local plumbing company and myself we tracked down several blockages in the pipework to the cold rads. Solid blockages! And lots of rubbish (grit, scale, rust) in the system. I think the problem must have stemmed from our first years in the house (eight...

Wouldn't such a problem affect all rads? Some of them are piping hot.

Thanks for all the replies. To clarify :- The system is 10mm microbore. First thing I tried was closing all radiators off except the cold ones, each in turn. Also tried this again after the Power Flush. The pump was certified 'ok' by a Heat Team engineer who was confident it was fine. He...

Bahco, Wow! I cant believe how quick I got a reply .... thanks! I read the FAQs as advised and, although these are very good, don't seem to help. I really just want to make sure that I'm not being led down the garden path re pulling up floorboards to trace the blockage. I.E. is there any...

Powermax 155 system. House is 8 years old. It started last xmas with two cold downstairs rads - rest were hot. Rads removed and flushed and refitted with new valves. No success. Have had the pumps and boiler checked out - all ok. Local Plumbing company put cleaner in two weeks ago and...

Hi jamsco - really appreciate your prompt reply. Tried option one (shut all but the cold rads down, etc.) with no luck on a result. Seems the pump might be the problem, then. Any idea where I can get one of these and roughly how much it will cost me? Do I need to get a fitter in to do the...

Two of my downstairs radiators are cold. The inlet pipes are also cold. wierd thing is that they are at different ends of the house (one living room, other dining room). I have disconnected both radiators and flushed them through. I have also replaced all valves on both, drained the system...
