the tub runs all out all jets and blower for about 15 minutes, then pops.
I ran a ground to the control panel into an 8' ground rod in the soil.
I replaced the GFCI with a new one only to be smacked by the 80 dollar price tag and still have the thing blow.
It ran for 2 year fine with no problems. now the wire gets hot and the breaker as well.
I have the tub wired in 6/3 unshielded wire in conduit 3' underground. the total run back to the breaker is 110'. as I say it was fine for 2 years until now.....
Any suggestions?
