I have a GVA-24 that is controlled by an EasyTouch 4. The valve is set to turn one way in pool mode and the other way in spa mode. After 3 years without problems, the valve has recently quit working correctly. It works just fine when the EasyTouch is in spa mode. The valve will turn in either direction, depending on the position of the ON1/ON2 switch. However, if the EasyTouch is in pool mode, the valve will not do anything, no matter what position the ON1/ON2 switch is in.
Any ideas?
