Hello,

My name is Scotty and I have a Calspa with the 2100 series control panel, it is showing SF which is the suction safety lockout. I have checked the filter the suction grills and there is no blockage, filter is alittle dirty but not blocked.

I found via the search mode a fix and proceded to unplug the the sensors from the mother board, I am still getting the SF code after doing this. Took out the filter and it still shows SF when I try the jets.

It will reset, by pressing any button, but if I try to use the jets it goes back to SF again. I also tried shutting power off at the breaker to clear the fault but it comes back.

Anyone with any advice or anything else to try?

Thanks in advance.

the SF fault happens only when I press the jet button on the control panel, after looking the system over pumps, filter, drains and all. There are no blockages, pumps spin freely, cleaned the filter.

I think I have a bad button on my control panel, the jet button gets used atleast 10 times more than any other and I think it has worn out.

Does anyone know if the safety suction switch is NO or NC?
