HOLIDAY POOLS

I had Lee come out on a service call to my Paradise address. They let me know they'd have a on-site diagnostic fee, which I agreed to. My spa was showing a FLO2 error.

Lee came out and checked out our Sundance 850 spa (Older, 2006 model) and measured the voltage coming from the board to the circulation pump and stated that it was not providing enough power. He gave the recommendation to replace the board.

After talking with him further on it, we talked about the work I had done on the board already with the relays (I replaced them and re-soldered them). He then stated that it'd probably be worth it for me to order the board and replace it myself as there'd be no sense with paying him since he believed I could do it.

I've since replaced the board (Cost me around $650), but the issue is still happening. The board was installed and powered up, no errors showing except the original FLO2 error.

I called up Chico Holiday Pools & Spas again and requested they come back out, as I feel it was misdiagnosed. Lee refused to come back out free of charge to re-diagnose the issue, as the board wasn't replaced by them. I'm not sure why that would matter as I am receiving the exact same error, but that was their stance.

As such, I wanted to leave this review for those who might be in my same situation in the future to make you aware. If you're looking simply for a diagnosis, I'd go elsewhere.

EDIT:
I verified the circuit board was set up correctly.

I also tested continuity for the fuses and other sections of the board, such as TB6 (What controls the sanitizer). All continuity works without issue, except the TB2 (black), which Lee stated must be the control board and subsequently blamed on my wiring. After a board replacement and verifying my work, I hardly doubt that is it.

I was only told the main board was the issue and wasn't told that other aspects, such as the flow switch or main control panel, could be the issue as well (Which is unconfirmed until I do further research - which I shouldn't have to do, as I paid someone else to diagnose and asked for their assistance after their recommended remediation didn't work). I'll reach out to the board manufacturer and see what else controls the relay for the circulation pump and update back, as I'm not convinced the main board is (or ever was) the issue. As they stated themselves, this seems pretty basic.

EDIT 2:

I disconnected the flow switch and sure enough got power to TB2 (black) for the circulation pump. This cleared my error for FLO2 as well. Looks like my flow switch is bad.

It's unfortunate that the shop wasn't willing to come back out and check it out, as I paid them to diagnose this. Especially since I shelled out $650 for a main board I didn't need + their fee to get nothing from it. Oh well.

I always get my pool water tested here and have gone to the other places in town and still holiday pools is the best! They always have everything we need and with good prices. I Can always get an answer to my questions, great and quality service
