    Vokera Excell 80SP Intermittent hot water

    Yep, tried than and can here the solonoid drop in and out. As mentioned in the last post i'm a little concerned the boiler was either not installed properly or has been serviced poorly, the missing screws and the missing fan gasket.

    Vokera Excell 80SP Intermittent hot water

    :oops: I was editing the last post but you got in to quick, the boiler has not been operating correctly since we moved in back in March (3 months after last service) and the house was on the market prior to the boiler being serviced. "I'm also not sure how good the installation/maintance has...

    Vokera Excell 80SP Intermittent hot water

    Wow, thanks for the quick reply. Are the parts easy to come by as i noticed from the Vokera site that this model has been discontinued. Having just scraped up enough funds to finally get a property a huge repair bill is something i could do with out, I'm pretty capable mechanically and...

    Vokera Excell 80SP Intermittent hot water

    Hi, got a really annoying problem that hopefully has a simple solution. I've got a Vokera Excell 80SP, no idea of age, it came with the house ;) We have excellent water pressure and the boiler is on the same level as all the plumbing. When turning on the shower, or any other hot tap the...
