Hi:I have LA Spa. S.Class Cleary Advanced Spa Systems LA-8 Gecko controller #1017970. This all information I found when I took the panel off.Problem: I hear the pump try to start. I open cover look at control temp says 32, water is warm. Using top side control I turn pump to low, it runs, turn to high it runs, temp changes to 101 degree F. I let the pump run everything works. Later in day or next morning I hear the pump trying to run. I do the same thing everything works great. Filter are clean, I just drained and refilled spa. What going on??Frank
Welcome, how can I help you today? What you are describing is a circuit board malfunction. If the topside reads 32 degrees but the water is warm then the thermostat is in need of replacing as well. 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. Some boards you can change the Dallas chip which is the memory chip, some you can't. You said this is a Gecko control, can you get me the part number off the board itself? If so look for a white sticker or label in the lower right corner and let me know the part number.Fix my Pool and Spa41092.0008516204
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.
That is a good sign. You may have a loose or pinched wire for the pump. Look on the circuit board for where the pump gets it's power, there should be 3 wires white, 2 blacks or red and black, one wire is neutral(white) the other two are for low speed and high speed, if you have a plug version that plugs into the side of the box then on the inside of the control box is the female end that the pump plug goes into off of this female plug should be the wires I am talking about they will go from the plug to the board be sure all the wires are snug in place and that there are no cuts. There still is the issue with the temp but lets get the low speed pump working first.

I did not fine any wire or connector that was loose, but I did push all connectors in to tighten. Display shows correct temp 100 degree f. It appears to be working, but no direct cause found????
Sometimes it is just a loose wire and when you tightened everything up you corrected the issue. How is the pump working?

How can I test if the pump timer program is working?
When you say that in the morning you hear the pump trying to run what sound do you hear? When this happens can you test the voltage going down to the pump I would like to know if the board is sending the proper voltage. Every pump has a starting or run capacitor which is like a battery in a car it sends the voltage to kick the motor over, if this capacitor is bad the pump can not run, however when you press the topside you can get the pump going so this is puzzling me. There is no way that I know of to check the timing sequence within a circuit board unless you know how to build one and know the inner workings of a circuit relay etc. The memory chip is called a Dallas chip and it is mounted on the board itself and can be replaced but I do not know if that is going to solve the issue at hand.
I thank you for the accept and I am here if you have any other questions good luck.
