    I have a full tank of water & the cold water runs fine but nothing coming out of the Hot taps.
    I can hear the pump clicking something ive never heard before when the taps are off.
    Open the cold taps & I hear the relay click & water flows
    Open the Hot taps nothing
    Ive opened what looks like a pressure relief valve outside & water flows until the pressure drops
    Ive downloaded the instruction manual & its useless

    Carver Cascade Rapide 2 with a pressure sensing pump

    any ideas ?
    water goes in one end & surely it should come out the other...........

    I have a hammer...........................

    most likely air locked, try opening all the hot taps with the pump off. then switch the pump on.

    I suppose I could take my probe out & try to manually power the pump & see if that kicks any air out

    Have your hot taps got a micro switch? If your cold water tap makes a clicking noise when turned on and none from the hot it may be a microswitch has gone.

    With the pump turned off and one hot tap turned on (all other taps off) try sucking water through from the tap. Be very careful if the water is hot.

    You could also blow down the tap which may dislodge any air lock.
