Thank you! That is very useful. That document mafia page looks vaguely familiar. I wonder if I saw that at some point and gave up, because I got this just now:
“Cannot contact reCAPTCHA. Check your connection and try again.”
I have little tolerance for any CAPTCHA. Since it seemed relevant and you already confirmed there was a gem in there, I made more effort.. enabled more and more layers of nested JavaScript, turned on images, and got past it.
It’s progress for sure. Holding the 1st auxillary button revealed the error code, which I have attached. Looks like this for anyone else with images disabled (black=unlit):

There is still a secret decoding ring missing, but if I can assume that the top row of LEDs are 1’s and 0’s from left to right, I apparently have error code 101 (in binary, which is “5” in decimal):
H5 : PUMP OPEN OR SHORT CIRCUIT
That’S not what I was expecting. I was expecting a tacho failure. The pump spun fine when I hotwired it and the tacho was clearly visibly broken.
The wiring diagram shows that the resistence across the pump should be 75.6 Ω. I measured 141.1 Ω using a crappy pocket multimeter on the PCB side of the wire (so long cable included). That difference seems huge. I’m not sure what to think of this. I don’t think the PCB would be sophisticated enough to measure resistence. So I wonder if I am misinterpreting the error code.
I cannot clear the error code. After displaying the error code, I hold Start/Pause for a few seconds and it gives a quick flash as if to acknowledge that the error should be cleared or that it took an action. But it returns to the same error state anyway.
