Below are examples of faults people have experienced with their Worcester Greenstar boiler.

I’ve had my Worcester Greenstar boiler installed and working well for over 10 years now.

Late last year it started to lose pressure slowly.
Water was leaking out of the overflow outside.

A local Worcester recommended plumber came and serviced it and replaced the pressure relief valve. This slowed the pressure loss for a while.

However the pressure/water loss has increased and now means I am having to top it up at least once a day. It drops from ~1 or 1.5bar to zero in a few hours.

No water is leaking out of the overflow outside. I did tie a bag over the condensate drain into the sink overflow, and overnight (with heating on low) it did collect about half a pint of water.

I’ve previously inspected as much of the groundfloor radiator pipework as I can, and found no leak. Though to be fair that was before Christmas when the leak was much slower.

Is there anything I can do to be certain that it is a radiator leak or a boiler problem? e.g. isolate the bolier from the pipework, to see if I still get a pressure drop? I understand I would need to turn the boiler off while doing this.

Obviously if it’s pipework, I need to be getting floors up
If it’s the boiler e.g. faulty heat exchanger I would get a Worcester Engineer in to fix it. Problem is I don’t want to pay Worcester £230 for them to tell me it must be a leaky pipe.

The local plumber is suggesting the best option is leak sealant.

Any suggestions would be very helpful.

We have a 9 year old Worcester Greenstar 27HE combi which have had repositioned in our house from a bathroom location to a new utilitiy room we had built as part of a small extension.
When we had it moved we went from a flue through the roof to a through wall flue and a new flue was installed.
We had a problem with the fan not working in its new location and so this was replaced. We searched countrywide to find one and eventually had delivered and instsalled.
We thought all was in good working order through the summer only using the hot water.
When it came to putting the heating on we encountered a raspberry noise when the fan seems to be ‘getting up to speed or slowing down’ (not sure).
We have had a bearing plate fitted to see if this works dispite some comments form Worcester stating that a bearing plate was not required on earlier models.
It had a full service and clean out and replaced the burner plate and seal and still the noise. But only when heating not DHW. Heat output at radiators is fantastic and gas/air ratio have been thoroughly checked and it is burning at approx 98% efficiency.
Gas valve has been checked and it working correctly.
What could it be?
Could it be an incorrect or faulty fan?
The plumber tells us that ‘boilers dont like to be moved’ and ‘you need a new boiler’ but Worcester advised that a boiler of this age is fixable.
Our next step is to get Worcester in to look at it but that is more cost.

Any help greatfully received.
