    HE30 ISAR DHW temp fluctuations

    New engineer from a new company, went through symptoms, showed him 2 replaced parts that we kept, said one definitely didn't need changed. He phoned Ideal and they confirmed his diagnosis of restriction within the boiler. Home serve were informed and long story short have now offered us a brand...

    HE30 ISAR DHW temp fluctuations

    Thermister has been changed but he said diverter valve was newly replaced on 28th August! Told him that engineer (last week) found it wasn't functioning properly and that he had to fiddle with it to get it to work! I assumed it was also being replaced. His reply was 'it doesn't matter' (as in to...

    HE30 ISAR DHW temp fluctuations

    Had a busy few days so didn't get a chance to post a reply. Yes, I think it was jammed. They sent another Npower eng' to give them the opportunity to resolve out. Have been without hot water since then as they had to order part from manufacturer. One of the previous engineers turned up this...

    HE30 ISAR DHW temp fluctuations

    I am going to ring homeservre again today. Our policy is with them, they pay the engineer so they should be on top of it. Turned it back on this morning, it started good, displayed 'd' so I turned on bathroom tap which after about 10 secs started to go warm then cooler, left it running to check...

    HE30 ISAR DHW temp fluctuations

    It turned cold again today, flashed LE so I turned it off. Put it on a little later, came back on as normal but went off again this evening. Tried turning off again but It now flashes S E when I turn it back on. The only pipe that felt hot was the one with the pressure gauge fitted to it.

    Yes, it happens on tap, no matter how slow you run it, the water doesn't stay warm for long which is what happened before.

    HE30 ISAR DHW temp fluctuations

    Hi, before I start I've read a vast amount of posts about this boiler now and realise it's problematic to say the least. We had ours fitted 2008 by warmsure. Shortly after we had a problem and the orange board was replaced, this also turned out to be faulty and was changed again within a week...
