I have a nautilus dish washer that appear s to be going through the wash cycle but I can't hear water going into the machine or the washer arms spinning around on the "main wash" cycle. The detergent compartment pops open but at the end of the full cycle.... The dises are still dirty and the detergent powder is still sitting in the opened detergent compartment. Are you able to suggest a solution to this problem. Kind regards.
