MECH-NOT-DRY
Whirlpool · Whirlpool WDTA50SAKZ 47 dBA Top Control Dishwasher with 3rd Rack
Dishes come out of the dishwasher still wet. Check that the rinse aid dispenser is full — rinse aid dramatically improves drying by reducing water surface tension. Use the heated dry option or sanitize cycle. Unload the bottom rack first to prevent water from the upper rack dripping onto lower dishes. Plastic items dry poorly because they do not retain heat — this is normal for convection-dry dishwashers. On models with a vent fan or auto-open door dry, verify the vent motor (see FAE1) and fan are functioning.
