[Happy Camper]

I have 230 volts going into the hot tub control box but only 120 going to the pump motor.

S/N and pictures help!

Khybers are really old.  I don't think they have been made since 96.  That being said, it is possible that the pump runs off the 20A circuit.  Making it only 120 pump, where your heater could be 6k, making it run off the 30A.

Therefore, everything could be running as it should

I have 230 volts going into the hot tub control box but only 120 going to the pump motor.

Having a 120v pump in a tub supplied by 220v is common.

Whats wrong with the tub?
