effective wattage due to cycling of 541 watts during

the dry cycle.



Water inlet temperature must be at least 120 F for

proper drying. Lower water inlet temperature will

prevent proper convection air movement and

increase drying time substantially.



If the problem is that the dishes are not drying

correctly, don’t overlook the rinse agent. A rinse

agent will improve the water sheeting action and

drying performance.



It is normal for the stainless steel tub and inner door

panel to retain water droplets even though the dishes

are dry.
