    I have a Mira Sport 7.5kw and am experiencing a problem with the temperature running hot and cold.

    I have carried out all of the initial tests and also replaced the flow pressure switch but still no joy.
    Have also tried different shower head and hose but no joy

    Could it be a costly fix?
    The shower is 3 years old so don’t want to spend loads on it as probably cheaper to replace

    Any ideas?

    I would check the inlet filter if its partially blocked this would cause the problems your experiencing. Cheers kop

    Thanks for this and checked it out but couldn’t find anything. Spoke with Mira and they said the heater tank might be scaled and that is what would cause the problem. I looked on top of the heater tank and there were signs of scale, so will now replace that and see if it helps.
