Boiler stopped working late Thursday 1st Jan. When restarted it made the most horrendous sloshing/gurgling/clanking sounds. Worcester support line engaged for ages, British Gas couldn’t come out ‘til Monday. Managed to get a local plumber to come out Friday who diagnosed faulty pump, replaced pump & still did not work (and still making the same noises), then told us it was probably the fan. Weren’t convinced, so sent him packing £300 later.
Managed to eventually get through to Worcester late Friday afternoon who sent out an engineer on Saturday. Within seconds diagnosed a frozen/blocked condensate pipe and said nothing would work until pipe was unfrozen/unblocked. He went off and we then spent a good couple of hours running hot water/using hairdryer up and over the section of pipe that runs outside and alongside the house (external pipe is lagged except for the 12ish cm of pipe that runs into the drain).
We then unscrewed the pipe from the boiler and ran water through (which indeed came out the other end) so we know it's no longer blocked, however, boiler still won’t work, and still making the same sloshing/gurgling sounds and goes into to a repeated power up/power down cycle until you manually switch off. We have Worcester coming back tomorrow but any ideas what it might be? I read somewhere that the condensate ‘trap’ can get a backlog of water in it? Could this be the case?
Would appreciate any help or advice.
Thanks
