Expecting to get the Diodes today to do my repair this weekend and then return the my board to the Cottage Hot Tub next week for testing. I will report back in a couple of weeks

Thanks for the links to the replacement diodes and I will order these for my repair and hopefully the board will be functioning soon. I will report back on my repair and testing once I receive the parts provided in the link above. Thanks Michael

I did some searching but I’m not familiar with sites and the components being listed. If you can provide links then I’ll see if mouser.ca has them which I might be able to get on Monday

Ok I’ll search for Digikey to see if I can source D3 & D7

This is great news and I wonder how I could repair mine. My neighbour is electronically handy so he might be able to help. How and where did you get the diodes so quickly? I tested my diodes and D3 is gone and D7 partially so I could use your help to attempt my repair in Windsor, Ontario. Do you have a repair picture th share? Thanks Michael

I have the same issue as you with the same board EL2000 M3 which it seems might have an issue with the diodes at D3 and D7 which another forum member with the OHH has identified these as faulty. He is going to replace them and report back if this is successful.

Thanks for posting this information as I now understand why my board stopped working correctly and that a board repair might be possible. I will do some testing of the board today if I get a chance to determine the faults I have also started to look at replacing the whole spa pack with a BP7 5.5kW and a TP700 which can then be connected to remote access with the wifi adaptor.

I see the area on the board with D3 and D7 and provided the some better images below

Ok this sounds promising as I have a EL2000 M3 in my Maax 461 Hot Tub that also just got stuck on OHH. There doesn’t seem to be a reason for this code to not reset so I will look at my board in the above locations. I will report back my findings tonight Thanks Michael

I also have a Max 460 with a constant OHH code after a night with the cover off and likely a dirty filter not helping by reducing the flow. The OHH will not clear even with the filters out and a cold full tub. Any help would be appreciated and did you solve you OHH code? Thanks Michael

How do you do a persistent memory wipe?
