    Ravenheat LS80T knocking noise then shutoff

    I have taken the pump off and had a look and it moves freely and power is definitely going to pump. Am I correct that if the pump has power then it should be running, there isn't anything on the pcb which sends a signal to the pump that starts it?? Can anyone think of anything else, to me it...

    Ravenheat LS80T knocking noise then shutoff

    Many thanks Tony The test indicates that the pump is not functioning. It is not spinning up at all. If I were to take the pump of to have a look at it's internals can I take it off without draning the boiler ??

    RaveHeat LS80T Little Star DHW running cold

    I have fixed the pressure problem -so presumably I don't need to check the expansion vessel? Is there a way of identifying if the dhw problem is caused by a heat plate blockage or the diverter?

    RaveHeat LS80T Little Star DHW running cold

    Thank Tony I have checked the saddle switch (thats the microswitch on the diverter valve thats held on with a plastic clip) Yes? If I take the clip off then the boiler fires up, if I press the switch in the boiler cuts out. How would I test the expansion vessel ?

    RaveHeat LS80T Little Star DHW running cold

    I shall get the diverter valve replaced then, fingers crossed. Tony mentioned that its not a totally recommended DIY job. Would it be "safe" to do myself, If I was very careful?
