White sticker has top and bottom number could be one long number.
Also, the second I opened the panel on the control box the low pressure pump came on. I hope this helps.
"All spa circuit boards have a built in timer sequence to turn the spa pumps on and filter the water twice a day for a set period of time usually 2 hour intervals 12 hours apart, but with the topside you can override this timer and make the pumps come on manually so again I say that the circuit board chip that controls the timing of the spa is bad"
How can I test if the pump timer program is working?
