Ideal logic 35 banging

[shyguy2005]

hi guys,

Had a quick look at job this evening was a ideal logic combi 35. When running for hot water makes a thumping noise. Have cleaned out condensate which defo was blocked up so clearly boiler has never been serviced. Boiler is about 6-7 years old .

Going back Wednesday first thing to have a closer look when I've got abit more time.

Any one come across a similar problem or anything I need have a closer look at.

Customer has also mentioned he's topping pressure up every 2 weeks or so. Will check expansion vessel pressure.

Not used to boiler breakdowns and I'm usually just installing.

Cheers.

check the sump as well they like to split around where the front inspection plate is

Funnily enough have swapped one of those on the same estate as this . Slight hairline crack in it. Think the whole estate has ideals fitted.

Never heard of a split sump on a combi , they seem to be only heat onlys ...
Is the coni pipe completely clear ?

Yeah that was on heat boiler but still ideal.

Cleaned trap out throughly but couldn't see down condensate pipe. Might be worth cutting into it then just coupler it back up.

Have heard there was a lot of problems with older ideals (isars) causing similar problems due to faulty electrodes????

I would try blowing down it or at least a hose full of water if you suspect anything . I know they have bother with flue seals but it doesnt give a banging noise, have your anyliser on when you draw HW it may show something

Sounds like it needs a full service as per manufacturers instructions first.

Then as it sounds like the condensate discharge pipe is blocked somewhere along its length so i would try and flush through or the other way if you can find where it connects to the drain I would disconnect from there and then vac it from that end to pull any residue through.

Also clean sink drain trap & bend if it connects in there.

Prob need a peg for your nose as I have had a few customers that must of emptied god knows what down there & it has stank.

Good luck with it,

Thanks.

Andy.

blocked condense is not going to cause banging

If its blocked and backed up it can cause a kettling/banging noise I have had that problem before with an ideal.

if condense was backing up it would gurgle never heard of one banging , how would it cause it to bang ???

I had one rumbling when the condense was blocking

ye rumbling and gurgling but never had one banging , must of had over 30 or 40 blocked condense on the logic

Sounds like a flow issue though the heat exchanger to me. Is the system water clean or dirty?
