Hey! I found the way to fix this one, was order the other one.
@DougL … It seems to work now, but I do NOT trust it, and I HATE to change the bulb in my laser (ask Alan!). So I would be thrilled for you to take this e-waste off my hands. I am not interested in fixing it for myself.
I did go through with using it this morning… as I was desperate to get a job done. I emptied the water as it was freezing, replaced with warm water, and the error code changed to e3… And it started showing what temperature it thought it was reaching again… AND it seemed to stop freezing the water…
YMMV, I will let you know when my new chiller arrives and is in working position. Until then I have to rely on the Cool Master 500 … It definitely is flowing because I did the ‘squeeze the hose’ test and got a different error code.

Cheers !!
