Well. Little update here.... Turns out I got a faulty board. The board is no longer replaceable either, so I've received a full refund and now have purchased a Gecko Ye-5 bundle to install. Let's see how this spa pack goes, and if anyone has any tips / insights for this pack, please let me know.

Yes, that was the new board. It was wet after leaving the casing off for a night. It had been dried up prior to running. Anyways, here's another picture with the now wrecked burn mark on the board too.

Bit of an update here. @CanadianSpaTech I reset the heater inside the tube, and yes you're correct that was causing the short. After having my tub up and running for about 3-4x days, I went to use the tub for the second time. While in the tub, I increased the heat to 102F. It could have been just unlucky timing or perhaps me increasing the heat.... but while I was in the tub, the pump intermittently came on / off, then died. Smelt electrical and quickly shut off the tub. The circuit board now has a black spot on it again....and is wrecked. This was a brand new board. The board has black marks next to P12 and above P38. I don't know what would cause this issue to happen, without a fuse break or GFCI tripping. All seemed fine until it didn't. I'm now tempted to upgrade the entire spa pack to the Gecko YE5 bundle, but don't want to order and install it if the same issue is going to occur.... I guess my question, is it possible the pump could have caused this issue? And therefore no sense in upgrading a spa pack without replacing/fixing the pumps? Thanks in advance

Further - Removed both leads from the heating elements, and tested for continuity from the element, to the side tube wall. No continuity. So again, I believe heater should be completely fine.

Yes, the heater element should not be touching the side wall of the tube. I can remove and double check. Below is the schematic and current wiring.

Hi. Looking for help from you knowledgeable people. gecko S class spa. dual pump 240V pump 1 (hi & low) At the end of last season, my tub died. Upon inspecting the pack, it had burned on the side nearest to the jumpers/Sensor Cables. Additionally, my heater element was also destroyed. i ordered a new board + a new element. Installed both. After installation, I’ve now started up my tub, and it seemed to heat quite slowly, although did get up to 100 degree temp. after coming back down the next day. My tub was not as hot, and the element died. Tested for continuity/resistance. prior to installing my new element, I wanted to test everything to ensure I didn’t repeat the mistake. Jumper 3 was in the right spot, but not plugged in correctly. i also noticed the tub when calling for heat was only displaying 120V. I then replaced the temperature switch. No fix. Then testing that cable for continuity I found an issue. After fixing the continuity, and later testing the voltage to the element got 240v Now, after purchasing a new element, I’ve installed it. Turned the tub on, and after 10-15 seconds, the GFCI breaker trips. After taking a lead off the element, and testing the element, it’s fine and still showing resistance about 14/15. i then tested pump one and running through a cycle low to high. It tripped the breaker. Pulling off the wiring from relay for low pump and putting back in… with one element lead off, no more tripping and pump will run. once again plug in lead to element, and turn on GFCI for it to trip immediately. I really can’t figure out what’s going on here… any ideas?
