Extra Gold

We found the fix to the Control Unplugged blinking led and the LimOk blinking green. It was that we did not take the black jumper wire on the old motherboard and move it to the new board, so it was missing on the new board. Just a newbie mistake, and the support where we bought the motherboard figured it out. Thank you to anyone who gave time to looking at this. I did learn a lot by finding this forum, and I'm sure it will come in handy in the future.

"Maybe @castletoniacan find a clue..." Thanks, I just sent him a private message and suggested he post here if he has any info.

Does anyone know what's new in the 77119 Watkins/Relay board with markings of 2018 and 158D? All the videos I've seen are using the 2012, 158C board, and it seems that is the one advertised. I'm wondering because I have a used Hot Springs Vista that we just got working. The previous owner said they had the old 3 relay board, and it was bad. So we got a dealer to install a new board, and they installed the 2018, 158D. Once we filled the tub, and got past a D17 led error by burping the circ pump, all worked well for a bit. The tub came up to heat, and worked great for 30 minutes, with all the pumps and lights going - probably pushed it too hard, and motherboard died. It was a 2003 board, it looked dead, with no LED's at all lit, and no circ pump - just nothing. It did have AC power input and no GFCI problem. So, we ordered new mother board. It is a new one, but not with the yellow square block in the upper, left, over what looks like the DC power. Anyway, now, almost dead, with no circ pump, but "Control Unplugged" is blinking red, and "LimOk" is blinking green. I think a D10 led is on solid on the H/R board. This thread has been great, and somewhat related, so I thought I'd start here. We already got some good phone support from where we bought the new mother board, but after trying all the unplugging of all the sensors and control cable, still same LED's blinking, and no voltage to circ pump. So, now I'm wondering about the really new date Relay/Heater board, and if it might have compatibility issues with the motherboard we installed.
