His is not typically a control panel issue but more likely a valve issue.

Your valves are set as follows wih a few minor variations.....
Pool mode- sucks from pool skimmer and or pool vac line and returns water to both the pool and spa.
Spa mode - self contains the spa , meaning water is sucked from the spa and returned only to the spa.
If your spa is draining then most likely one of your electronic valves is failing...most likely it's the return valve so what is happening is the water is sucked from the spa and returned to the pool instead of self containing the spa.
Easy check is to be next to the equip when spa mode is selected and two valves should move and align properly, the return side valve is most likely not moving or it is not moving into the correct position.
The fix is either adjusting the valve acuator or buying a new valve acuator.
Another thing to check is on the main panel circuit board to ensure the return and auction 3 pin plug ins are still connected.
