Never come across this before..

Boiler in demand for heating, sounds like running water from the bottom of the flue where it meets the condense trap, also a gurgling sound from the terminal (went to check for blockages). Condense run blocked? Boiler keeps locking out.

Also, fan sounds like it's taking off at times. Checked fan and no apparent faults. Spoke to Worcester who said could be the bearing membrane.

Anyone come across these and can shed some light?

Cheers

condensate trap probably blocked,have you cleaned it?

 

[ShaunCorbs]

Had a few condense trap not cleaned out (also see water coming out the flue terminal if horizontal)

 

[jaydebruyne]

No.. literally just went to have a look, gonna quote to do the works as didn't get there til 7:30 this evening.. gonna do it all when I replace the membrane for the fan. Also gonna replace his flue as it's in a bit of a state from builders moving the boiler location when doing an extension

Yeah this was horizontal but didn't see any water coming out, exhaust was clear

And me,also seen the 21.5 block solid if its connected to a sink,doubt its a bearing plate as worcester have advised,these normally vibrate or a smell of gas through the fan when they fail

 

[jaydebruyne]

So could a blocked condense cause issues with noise from the fan? Since it's linked to the flue...

Depending on the trap fitted they block very easily,would remove it too check,and check the condensate run

I smelt gas.. had to put a sniffer to it at one point but it went

Yes,it causes the boiler to gurgle

check trap and run first,if there is a bearing plate issue you will smell gas through the fan motor

Ok cool.. well I'll order it just in case.. cheers guys 🙂

There not expensive,about a tenner,got 2 to do this week

Had one just under half full of condense sounded like a washing machine when fan was running

 

[ShaunCorbs]

Would say it hasn't been serviced for 6-9 years

Pretty much what this sounded like!

So the bearing plate & membrane sit inside the fan don't they? So take the fan out and take apart the fan?

You half way there to do a full service if there's money for the extras jay (new burner seals and electrodes etc)

Might just sell it that way Shaun.. Makes more sense. New flue, boiler service etc - sounds tidier!! Cheers 🙂

So the bearing plate/membrane is inside the fan, right?

Without looking it up don't have a clue sorry , why new flue?

Although it's not leaking (tested it), the builders gaffer-taped the elbow joint, all screws were missing (which I replaced) - I just don't trust it. Plus Worcester said the blockage could be at the flue rather than condense trap so was gonna take the internal flue apart to inspect/clean and while I was at it replace the flue.

Fair enough, Replace the flue don't even bother taking it out and inspecting it

Unlikely the flue is blocked / restricted tho

Ah ok.. don't want to create work if it's unnecessary! I'll service it with new burner gasket and electrodes and see what happens.

Cheers Shaun

Unless you get ppms in air intake or it looks that dodgy tbh depends how it's been installed if it's a quick in and out do it least your sure

Saw one last week & it was bubbling

Condense pipe blocked

 

[mfgs]

When the condense blocks it gets very noisy. You can take the little inspection cover off at the sump and check. If it hasn't been serviced that will may well be blocked up a bit too.

The bearing plate, is it behind the fan or inside the fan?

Behind it

 

[jaydebruyne]

Behind it

Cool - cheers mate

 

[jaydebruyne]

So after servicing the boiler yesterday and leaving it in good order, I get a text today saying same thing has happened. Shoot over there as only round the corner and wanted to make sure it wasn't my work that caused the fault.. I investigate the condense run and find that the builders have connected the run with a flexi hose underneath the cabinets and run it back up to a inch and half tee.. tut tut. Got me another job out of it though to rerun the condense 🙂 sweet - cut the existing pipe and run it into a bucket for temp repair!
