    Halstead ACE HE30 combi boiler dhw issue, intermittent no hot water worse when heating been on. replaced hydroblock, diverter actuator, pcb and thermistor. None of these have made any difference also flow from hot tap same as from cold tap suggesting filters and heat exchanger okay. Any suggestions please scratching my head on this one.

    Had two gas safe engineers fitted the new parts both fitted new hydroblock and pcb only for the problem to return a few months later, I fitted the thermister, just trying to get a handle on it before I call out another engineer.

    Ok I would wait a while until the others come back , they might be more clued up specifically, but I do seem to remember they were never the best heating units. Ie boilers that have always been in the naughty corner even when new
