Worcester bosch greenstar 28i Junior no HW

[christhescott]

I have a worcester greenstar 28i junior boiler in my flat, its about 7 years old and has never put a foot wrong apart from losing a bit of pressure over the course of the week. I've moved out of the flat and its been empty for about 8 months, boiler unused. Tried the Hot water at the taps today and it was barely warm and the boiler was making a cycling noise like it was trying to work but cutting out. I tried putting the central heating on and then trying the hot water again and the hot tap worked as it should. Can anyone advise on what this is likely to be and if so how much am i looking for a repair? I noticed when I used the filling loop to top up there was a bit of water came from came up inside the boiler somewhere, so this could be related?

It looses water every week?
did you check the pressure before useing after 8 months?

The pressure loss:
is because it’s loosing water from somewhere, it could be related to what you said, but I’ve a feeling may not be. It may be a radiator leak, expansion vessel pressure loss or pressure relief valve discharging.

The hot water issue:
I think what you have is a leak on a part dripping onto the diverter motor and causing it to stick.

Hi, when i lived at the flat it would need a top of water every week or so. Couldn't ever see any signs of a leak from any pipes. I was last at the flat 6 days ago then topped the pressure up to 1.2 bar. Yesterday I think I tried the hot water first, didn't work so checked and the pressure was a bit low (not at 0 though) so topped it up and noticed a bit of water falling.

Best get GS engineer round to check pressure drop issue . Has it ever been serviced?

 

[christhescott]

No, i've never had it serviced since i've had it so will have to pay the price for that now. Would it be better getting a gas safe engineer that specialises in WB boilers or does that not matter? Will need to get a gas safety check done at the same time

Yes if its leaking water out of the external pressure relief pipe
Lots of people wont touch it as its a nightmare job

Most Gsi 's will have knowledge of these boilers they need servicing every 12 months and any small faults need to rectified , if the boiler sump is not cleaned then often the boiler will fail. You need a Gsi to attend . Kop

Suprised it’s last 7 years without a service with it being a Worcester !

you would be surprised had a couple once never serviced there boiler just put that money into a new one most of them lasted 9-11 years

If there’s is the chance that many things will need changed, would I be better getting some kind of maintenance package?
