AlaninTx Posted April 23 Report Share Posted April 23 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!

CanadianSpaTech Posted April 23 Report Share Posted April 23 Test the 2 green buss fuses that say SC25 or SC 30 on them. Does the heating/filtering related pump run in low or the circ pump if it has one? Test the incoming power and make sure you have 240V red to black and did not lose a leg in the gfci when it took the hit. Quote Link to comment Share on other sites More sharing options...
AlaninTx Posted April 23 Author Report Share Posted April 23 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. Quote Link to comment Share on other sites More sharing options...
AlaninTx Posted April 25 Author Report Share Posted April 25 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. Quote Link to comment Share on other sites More sharing options...
CanadianSpaTech Posted April 25 Report Share Posted April 25 Most common trip cause is the heater element. Disconnect the heater from the board and see if it holds. If it still trips disconnect each component one at a time until it holds (pumps, Ozone). Post pics of the circuit board and the schematic on the inside cover so we can see what you have and how it is wired Quote Link to comment Share on other sites More sharing options...

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 Quote Link to comment Share on other sites More sharing options...
CanadianSpaTech Posted yesterday at 11:17 AM Report Share Posted yesterday at 11:17 AM Most of Balboa documents are direct to PDF so can't post links here. Research balboa persistent memory reset and also TEST mode. Try and do a reset. Always remove filters when testing for flow issues. Remove them from the equation. Might want to test the sensors or try a new sensor set if all else fails. Quote Link to comment Share on other sites More sharing options...
AlaninTx Posted 9 hours ago Author Report Share Posted 9 hours ago 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! Quote Link to comment Share on other sites More sharing options...
CanadianSpaTech Posted 2 hours ago Report Share Posted 2 hours ago The heater just buy an element and not the entire heater tube assembly. I have dealt with many power surges in the past and they can do a lot of damage to spa packs and you have to go through each step along the way. I have the advantage of having parts available to check each step. I would order and install a new heater element as you know it's damaged and tripping the breaker. Next I am trying a memory rest. If that fails then I am on to sensors. Testing or replacing. If all that fails a new spa pack. Or go straight to the pack replacement and get it all in one. 54301 replacement. See notes here: https://www.hottuboutpost.com/coleman-460-spa-pack-103735-balboa-powerworks-el2000/ "Existing pack may say 54301-01 on the top of the Balboa EL2000 Series control box."

Spa Board Doctor Posted 1 hour ago Report Share Posted 1 hour ago Hello, The solid "OHH" error is caused by a failed component on the circuit board. This is a repairable failure. SpaBoardDoctor Quote Link to comment Share on other sites More sharing options...
