The Jacuzzi isnt recieving power

There is a ground fault somewhere...you need to isolate it with an ohm meter.

What is the problem you afe having with your Jacuzzi Water Heater?
Is this a Jacuzzi Hot Tub?-- Do you have some indicator lights on?-- what color are the lights?--
Is the Circulating pump running water thru the heater element?
Tell me more!-- Let's walk thru the system, and figure it out-- Mack B

The # 8 wire is a bonding wire for the hot tub or jacuzzi. It is to interconnect all the metal parts and equipment associated with the unit, pump, pipes, handrails, and also now there is a bushing that goes in the piping run to bond the water itself .
This wire will be incdentally connected to the electrical ground when it is bonded to the motor body.

get an electrician. you need to follow the code for the size of wire to use based on number of amps of the motor and how far away the pump is from the power outlet.

The heater will only fire if it has water in it. If you just got the house, make sure the gas/electric to the heater is on. Turn off the pump and turn it back on.. See if that works. good luck

im not a great expert in this field but try putting some dish washer tablets in water when running to see if they can clean out anything,about 3/4 tabs

sounds like the rubber seals are going bad, does it recomend to run cascade thru the jets? this might be harmful to the gaskets and the pump, you maight want to disconnect the hose and flush out the tubes going around the tub, but I would call jacuzzi and ask them if this is good to run thru there, thye might be able to help you with the gaskets, questions over the phone do not cost you, call them, ask for repairs section good luck
