Hi @CanadianSpaTech, thanks for your response.
The equipment is definitely made by Gecko. Attached is a picture of the brains of the spa and also of the keypad/screen.
I found that this company sells the replacement part, but I'm worried that exactly the same part will last exactly the same time, which was just a little over a year.

Perhaps I should replace it with a newer, revised, but compatible keypad/screen from Gecko? Is that possible?
Also, would it be possible just to replace the LCD portion?
Your help is appreciated!
