two speed pump and heater does not work; just makes clicking sound at control panel.

I have a hydro spa hot tub; for no apparent reason, the main pump (2 speed) and the heater quit working. When you try to start the pump, the circuit board makes a "clicking" sound. The control panel just show "--" for this pump. Anyone have any ideas ??????? Or what I should check (I do have a multi meter)??????? thanks,

The heater may not be working right now because the pump is not coming on. It has to be running in order for the heater to come on unless you have a small 24 circulation pump. It sounds like the circuit board is not sending power to the motor but you should verify that with your meter. Since you hear clicking I don't think it's your topside panel. Does the pump come on automatically like for a filter cycle or heat call?
