Hi all,

My kind brother gave me his old Hot springs Prodigy - which is great.

When I got it up and running it would occasionally trip the 20 amp GFI. (monthly). This would only happen with the jet pump running after about 10 or 15 minutes of soaking. The heater and the circ pump work fine and never by themselves trip the circut.

After 4 months the tripping became more frequent and occured sooner after the jet pump was on - say 1 or 2 minutes. Eventually it happened virtually every time we used the tub. ( trip only happens with the jet pump on, not with the heater or the circ pump)

One it trips - if i give the GFI a "rest" for 30 minutes or so ( sometimes longer)- I can then run the heater and circ pump. Conversely - If I don't give the GFI a "rest" - it trips again - almost immediately without the jet pump being on

Last weekend I replaced the original 10 yr old jet pump (thinking it was the culprit ). But no luck! -the GFI trips again after 15 or so minutes - so I am back to square 1

Can anyone suggest a trouble shooting procedure that i should go through to try and resolve this?
From other posts I have read through:
could it be something is wet? - circ pump issue ? Bad GFI?

Thanks -any help is much appreciated

Is this hooked up 220V?
Do you have a serial number?
I suspect a weak breaker.

Thanks for the reply.

Its a 220 Volt model H. (I'll post the SN when I get home)

The GFI was purchased new and teh problems started after only a few months....but I guess that doesn't exclude it as the cause.
