    * Resolved * Air in the central heating system

    @muggles If this time comes, is there a superior magnetic filter you'd recommend. There was limited choice at time of purchase, the effort to took to fit it I'd be keen not to repeat if indeed a replacement was required. Can't complain, it's done the job fairly well. But I've no experience of...

    * Resolved * Air in the central heating system

    May now refit one on the manual bleed valve types to the Fernox F1 magnetic cleaner as still unsure of the suitability of auto vent value on this unit even though it appears to be working just fine. Did message Fernox some weeks ago to ask them if how I intended to proceed was a viable option...

    Feel compelled to post this as this issue has been the bane of my life for last month. Finally this evening discovered the problem. Searching various forums it appears many people have similar issues, this is how resolved mine / something easily ruled out. Problem - Closed loop system...

    Worcester Greenstar 24I System NG Part Issue

    Thank you once again for your response. The picture below shows it seems to be the bottle type trap Syphon by Poisonata posted 29 Oct 2020 at 7:47 PM hence my initial thoughts regarding the later model of heat exchanger (according to the serial FD number) with the new sump appear to be...

    Worcester Greenstar 24I System NG Part Issue

    So the damage was originally ribbed effect, he acknowledged this was fairly common. But now a small split has appeared in the casing at the top with evidence of leakage albeit minor. I've observed this while he had the cover off, it's fairly apparent the heat exchanger has seen better days...

    Worcester Greenstar 24I System NG Part Issue

    2 by Poisonata posted 28 Oct 2020 at 8:44 PM Our boiler (see above picture) which I've identified using the GC Nr needs a new main heat exchanger. Advised by heating engineer, excess heat over time has caused damage to the outer aluminium case. I'm assembling all the relevant parts he...

    Worcester Greenstar 24i Heating Issue

    Follow up - Drayton Synch Motor purchased from Screwfix (see above for picture). Fitting took approximately 30 minutes, very easy. Only difficultly was access as it's in a tight space. Working a treat. Thank you so much @Gasguru for correct diagnosis. Never the repair that's the issue, it's the...

    That's good to know. Screwfix is only round the corner / got them in stock.

Slightly galling when everyone else seems to have had the whole summer off paid :( Maybe not a...

    Worcester Greenstar 24i Heating Issue

    A little further reading it seems for ease (avoid draining the whole system down / replacing the valve assembly which doesn't appear faulty) a straight swap of the sychron motor is the best (cheapest / quickest) fix. Found one on Amazon that's suitable for a tenner. Even better :)

    Worcester Greenstar 24i Heating Issue

    Thank you so much. And you are spot on. Removed the housing from the zone value. It appears to make contact with the microswitch but does not depress it. A quick nudge with a screwdriver to fully open the value and the boiler fired up. So I'm off to get a replacement V4043H1056 Honeywell...
