Thanks for your inputs!

Appreciate the feedback, can you elaborate on your suggestion of Balboa over Watkins/Caldera?

and the topside still read 115 degrees? Was the water actually 115 degrees Yes it still reads 115, water was never that not. Yes, all of those functions still work. When I reset the breaker, the LED reads 100 and a few seconds later it jumps to 115. The tech put a probe in the REG THERM input but did not touch the LIMIT THERM input. If it's a high limit trip, does it make sense to replace the high limit probe or a fuse on the board? thanks for sharing the manual and I am in the Ottawa area.

See attached pics of both the topside and control board. thanks for your help!

Not really specific, he said there was something going on between the top side control and board. For troubleshooting, he connected a temp probe to the REG THERM input on the board and reset the breaker. After searching the web, I am inclined to do a few sensor tests of my own, fuses, etc. Perhaps pick up a new temp and high limit probe to start with.

Control pad had 4 dashes displayed on the LED. I removed the filter, reset the breaker and it was corrected so I originally thought it was a flow issue. However, top side control now reads 115 with flashing READY icon. The pumps still work but no heat. Service technician arrived and took a quick look at the tub. After about 5 minutes in he advised that I need a full retrofit (control box, top side controller, heater, etc.) to get the tub working again. Any other advice or steps that I can do myself before moving forward with the full retrofit.
