Hi,
I'm new here, and was hoping that someone could help.
I have a Vaillant EcoMax 828e. Within the last yeat I have replaced the DHW heat exchanger due to scaling up, fitted a combimate. This sorted that problem,
Recently the DHW has got intermittent with getting hot. The CH works fine, rads get nice and hot.
I have replaced the Divertor valve as thought it might be this, but now since changing the DV the DHW is only luke warm through all taps, shower etc. However if I turn a basin hot tap on and then the shower, the water comes through hot. - it is as it needs a large flow volume to get the hot water through otherwise it is warm.
I have thermistors coming to replace, but if this does not work, could it be the PCB?
Thanks in advance.
