HELP!!
When we are in the tub, we are hearing a rapid switching/clicking sound coming from the pack. When we examine it, the heater light is going on/off rapidly. What is going on, and what do we need to replace?

The pump : Hurricane/Amps 15/24/40 / volts 110/220 / Cir brkr 20/30/50
The Tub : Dont know, but it is a candy striped tannish-brown tub
4 person?
The controls : push button/ air control

HELP HELP HELP. Thanks.

sounds like a bad contactor

do you have a separate pump for your heater? It would be a small circulation pump, and they are run by a pressure/flow switch. What is happening is the flow switch is cycling on and off when you have the jets on. You can try adjusting the pressure setting on the switch, or replace the switch all together.
