The good news - the buss fuses measured ok. the Bad news - now the 50 Amp GFI trips whenever I try to turn on the power. Something must be shorting out. I think I’m in for a long ride. any and all ideas welcome.

I’ve been having a guy named, Phil, at Easy Spa Parts in Oceanside,Ca send me spa covers for about the past 10 years and I’ve been very happy as they’ve been as good as the OEM covers. think they have a web site easyspaparts.com .

I’ll try the Buss fuses today. Pump/heater does not run at all. i believe the incoming power is ok, but given the power surge, that is certainly worth checking.

We had a power surge last night and when I went to use my hot tub (about a 2007 Coleman (Maax) 461 with Balboa electronics, it read “STU” (motor stuck?). As usual, first troubleshooting step - power off and power on. That replaced the message with “HOT” (something overheated?). Everything was nice and cool, so I powered it off, moved A1 up to test mode, powered it on and got “OHH” (Overheat?) , which is where it now sits. Kind of strange as it happened in the middle of the night with the tub in standby on a 40° F night. I just started researching it, but figured I’d reach out and see if anybody has the “magic bullet” (not the food processor). I took a pic of the Balboa circuit board if that helps. Thanks, in advance, to anybody that can get me a couple more nice nights in the tub, before the brutal Texas summer rolls in. All thoughts and opinions welcome! Thanks!
