Ground fault, when I disconnect the heater, breaker is fine. When it trips it is instantaneous and to middle position

I replaced the heater with a new one. Hot tub is 13 years old and no problems before I replaced heater. I'm wondering if the short is in the heater

Can you check to see if your heater is grounded?

Expert:  George Smith replied 4 months ago.

I wouldn't be shorted if your not tripping the breaker !

Customer: replied 4 months ago.
It is grounded, heater has a ground and there is a separate ground wire on the outside of the heater to a bus on the board

Can you test from the leads of the heater to ground and see if you get a reading ? You shouldn't!
