Worcester greenstar Junior 28i possible leaking hex.

[solutions]

I posted about a week ago regarding my own boiler (the above) not fitted by me as I cant stand Worcester boilers.
I suspect the hex is leaking as boiler drops pressure even with service valves closed.
I have had it off for a good day now have topped it up twice to around 2 bar and the pressure consistently falls. No sign of it leaking through the prv which I replaced last week after I managed to snap the lever off the last one which then naturally refused to seal. I emptied the condense trap but it has not filled so if the hex is leaking it must be slow and possibly drying before it reaches the sump. Are there any other indicators that its shot below are some pics of the hex which shows signs of bean tin ribbing, and slight rust coloured staining on the sump seal. I think I know rge answer to my question but really dontvwant to replace the boiler right now but resent the idea of giving Worcester money to replace a hex less than 10 years old.

Ring worcester and see if the hex is in warranty, 10 years after 2007 i think

I have serviced it annually. Since I bought my house. It was only put in the year before. I just dont know how long its been running on low pressure as its in a loft. Above a ground floor bathroom.

Serviced every year and you still got bean tin?

 

[solutions]

Yes, as far as I recall the ribbing wasnt there last October and the boiler has not stopped working. I only whent up to look at it when dhw stopped flowing constantly but came and went as if the hall effect/ flow sensor was stuck or something else interrupting the provision of heat to the plate to plate despite attempting to fill a bath with hot. Im with you Ermi boilers should be maintained. I would make the same call if I had found it in anyone elses house but mine.

Had it out and cleaned the strainer which had what looked like flakes of cast iron in it, but could have been solder as didnt check if it was ferrous. Had the hydro block out to change prv anyway so was no bother. These worcesters are a rubbish design and layout. And theres no room to get your hands in anywhere. Odd thing is I have had the boiler off and issolated for over a day now and the pressure dropped from just over 2 bar but keeps levelling off at just over 1 bar and im not seeing any volume of water exiting the condense.

Vet on flow to top of hex possibly weeping

but have you stripped it every other year,removed the baffles and changed the red burner gasket,i suspect you have not,sadly for me i service a lot of these heaps it needs a full strip down every 2 years

Indeed I have not. Probably 4 years before it got its first and that was just because I felt it probably should be checked internally as im quite sure The Mi s make no such stipulation providing the fan pressure test and combustion analysis is within spec. They are indeed heaps. I am fortunate not to have serviced many. Resented buying the baffle removal tool and brush. If its a specialist tool and required to carry out a full service they should give them away.
