Trouble Shooting Assistance Needed for CircuPool UL40

[Seadweller]

Greetings!

I have a CircuPool UL40 unit that is currently throwing a "No Flow" light. The light is solid, meaning the unit is not generating chlorine. There are no flow issues with the system. Oddly enough, the "on," "generating chlorine" (when in auto mode), and "superchlor" (when in on mode) lights are illuminated, but the cooling fan is not running, which leads me to believe it's not activating the cell, regardless of the lights.

I replaced the flow switch to no avail. Next step was to clean the contacts, light still illuminated. Final step was to cut the switch off the old wire, jumper the two wires, and plug it into the unit. Again, no change.

Would this indicate the main PCB needs to be replaced?

Thanks!

How old is your system?

Make a warranty claim with Circupool.

They have strange failure modes and quality issues.

It's around 4 years old at this point. I went ahead and ordered a new PCB. With a new replacement now over $1,000, I figured a new PCB at $150 would renew the system.
