Ended up getting the EL2000 as per the link that was sent. Looks like a direct replacement and it will accept the existing top side controller. The BP7 looks like it would have worked as well, but would have had to change out the topside controller (which was included), but I decided to just go with the simplest replacement. My thanks to all that replied.

Spa Board Doctor - repairable how? Feel free to PM me at Alan @oddpost.com my friend in Canada - the spa is 18 years old, so replacing the “engine” is not a surprise., ill try the persistent mem switch and test mode, but my gut says it’s fried. seems like the Spapack that you mention in your link and the Balboa Bp7 look like good candidates. They might even be the same, as balboa seems a bit cagey. a few years ago, I’d have no problem fixing it myself, but age is creeping up on me. Fortunately, I have some relatively honest spa techs around. thanks for your replies. Gives me more faith in the internet

Saw the instincts for persistent memory and test mode. Right now, the hearer appears to be the culprit for tripping the GFCI. Now disconnected just OHH and the pump will try to prme i try the test mode and persistent men dip swithes and see if that goes anywhere. looks like I’ll need a new heater, and possibly a new logic board. Since Balboa does not make 54301 anymore, I may have to go for a new spa pack and topside controller (ugh), thanks for your replies!

You are correct. It was the heater. GFI did not trip once disconnected. Unfortunately, it is still. Stuck with the OHH error. It turns on the pump, tries to prime, and then shuts off. The spa pack is a Balboa 54301

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!
