Welcome to the site. It could very much be the selector valve. Take the connector off the valve, and set your ohm meter to 10 ohms. here is the pinout from memory (not always the best) Pin 1 is at the top.
1>> Motor +
2>> Motor -
3>> Tank Common
4>> One tank
5>> The other tank
So if you ohm out pins 3,4, and 5, at the very minimum if you test all the possible combinations, you should find continuity between two of the pins.
