Hello and thanks for the help in advance.

I aquired this spa 3 month ago. I believe it is 5 years old and hasa ap-1400 control unit that controls 1 pump high and low. The low flow will not come on with the clock or with the tstat. If I turn on the High flow with the air switch, The pump runs and heater works. I looked at the schematics and I think it could be the relay?. Any help would be appreciated.

Thanks

Do you have a separate circulation pump? If so, might want to check that out as well.

I fixed it!!! WOOhOOO! IT was the starter relay. Ordered it online for $32.00 to my door.

Thanks
