Water escaping from the outer drum during spin cycles. After 12 years, the bellow and vent hoses were deteriorating. Because of these breaches allowing moisture into the upper cabinet, the dispenser errored when it was exposed to the moisture. Having these new parts solves this problem. I had to clean the dispenser and the actuator and reassemble.
These were fairly simple to replace with basic hand tools in one job. It is made easier with 1/4 drive ratchets and nut drivers.
