    Your valves are sticking. You can try cleaning them, some guys have made them work again, but I never had any luck doing it. If you can afford it, just go buy all 3 new. My local NAPA has them, call yours. I paid like $120 for mine...If you never messed with them before, it's simple. Take the big 7/8 or whatever nut off the solenoids, pull them off, and use a deep socket to pull the valve out. I leave the wires attached to the solenoids, no mixing them up that way.

    Like my MM-1..
    Here they are highlighted darker than the rest of the pic..
