Carl, With the soap not dissolving, you will want to make sure that you are running hot water in the sink, make sure that the water temperature of the incoming water is a minimum of 120 to 125 degrees Fahrenheit. If these check ok then you will want to test to see if the dishwasher heater has continuity and that there is nothing caught in the pump assembly that would cause a restricted or no water flow to the upper and lower spray arms.
