Sorry for all the unnecessary posts. Moving that jumper wire solved the problem. also jiggled my LED spa light connection and it works again as well now. If i get a chance to take that circuit board apart i will report back if i noticed any problems with it. Like cold/cracked solder joints or stuff like that.

i think i see what problem is. Ill try this later on, but i think that will likely solve it. move the jumper to switch power from blower to the pump 2. i dont have a blower on my hot tub.

New Spa pack installed. Set the dip switched to match my tub. did the persistent memory wipe as per instructions. everything works great except my #2 pump behaves as if its a 1 speed pump. The topside controller shows icon for low speed (on 1st push) - then high speed (on the second push). But the pump only starts up at the second push and it goes right away to high speed. Ill send a pic of my old system label (54301) and dip switches(all red) and then the new system label (55065) and dip switches(blue/red). maybe someone will notice an error in my switch set up. Thanks

I ordered a new Balboa Spa Pack EL2000 exact same as what i had but slightly upgraded i think. They said it would be a perfect swap out. (circuit board looks identical to mine) Happy to find one in Canada to avoid long delivery delays. so for complete new pack was $674 ($520USD). after i have it installed i might have a better idea about condition of old circuit board. I forgot to mention that when i was trying to uninstall the circuit board, i was having a bit of an issue undoing the 2 nuts at the heater element (see pic). the were seized pretty good with rust. The bolt was actually turning as well as the nut (didn't think that seemed right). At that point i figured ill just order a whole new pack since likely the heating element may be getting old as well. hopefully that will getting me back up and running. arrives tomorrow.

Thanks for all the advice. I’ll take the board out today and see what kind of condition it is in. The front, from what I can see looks really clean. But I will report back. Worst case I will likely replace the whole pack. As mine looks to be about 13 years old. If I do replace the whole heating pack, any recommendations on which would be a good easy fit? Or maybe which brand/ model to avoid? thanks for all the help

My Ohms reading are (when i set my reader to 20K Ohms): Sensor A : 62.1 Sensor B: 61.9 Please let me know if this is a problem. Thanks for your help

Ok, good to know. I thought that if the ohms was 0 then it is bad. I will check it again. The fact that the error message is the same Snb when i switch the 2 plugs on the circuit board, is that an indication that it is not the sensors? since the error code doesn't change to Sna? I am going to get a new reading on them right now.

I checked the resistance in my 2 sensors. they both seem to be fine. With very cold water in my tub, they measured 58K Ohms which i think is normal when water is that cold. So it seems like something must be wrong with the circuit board. Has anyone had this issue and managed to resolve it. Hoping to avoid buying a whole new circuit board when it is likely just a part that is faulty. Would a bad or stuck relay cause this error. On switching the breaker on, I do here a click and then very shortly after, 2 other clicks. I am assuming those are relays clicking, I'm just not sure if it is supposed to click like that or is that a sign of a bad relay? my circuit board is a Board Maax 460 EL2000 M3 54302 which i believe is same or compatible with 53834-04

Glad to find this thread. Having exactly the same issue with my 460 Mach3 controller. Also tried switching the sensors at the plugs. But got the same error Snb. So that tells me the sensor is likely not the issue. If anyone winds out possible remedy. Please post it here. Thanks.
