Hello Aaron, It is much more likely that the water valve is sticking mechanically and the water fill assembly has dribbled water into the base. This will float the flood sensor float and cause the unit to only drain. Wick the water out through the opening where the water valve goes and install a new valve 00425458.

Hell Ron. It sounds like the control may be bad, but first check and see if there is any water in the bottom pan causing the unit to go into drain mode. If there is water there, you will need to look and see where the unit is leaking from. Hope this helps.
