Both Drawers Stayed Wet Even Though the Fan Ran

The useful question was not only whether air moved, but where this uncommon KUDD03 platform generated heat and whether the required assembly was still obtainable.

KitchenAid kudd03 kudd03dtss3 Poor Drying Both Drawers

What was observed

  • The exact model was KUDD03DTSS3.
  • Poor drying affected both upper and lower drawers.
  • The fan was reported to operate.
  • No separate visible heating element was found.
  • The discussion proposed a heater built into the circulation assembly.

A similar symptom can have a different cause on another drawer dishwasher. Rinse-aid use, water temperature, fan operation and heater architecture still have to be separated.

The exposed upper drawer with its fan assembly circled; the heater-integrated circulation pump remained a separate diagnostic branch.

Why parts availability belonged in diagnosis

This was described as an uncommon platform. Before investing time in a hidden heater path, technicians advised verifying that exact-model parts were actually available. A catalog listing alone was not treated as proof of stock.

The source ended before the heater circuit was measured or a repair was completed.

Safe observations before service

  • Confirm whether both drawers are equally wet.
  • Note whether dishes feel warm at cycle end.
  • Record whether the fan can be heard in each drawer.
  • Provide the complete KUDD03DTSS3 model before parts are quoted.
Electrical safety: integrated heater and circulation tests require internal access. Disconnect power and do not measure heater supply during a live cycle.
Unexpected turn

A repair that did not follow the obvious path

An unusual turn supported by the case record Sub-Zero Not Cooling One Month After Sealed-System Repair A Sub-Zero stopped cooling a month after compressor and evaporator work. A clean evaporator shifted the diagnosis toward an oil-line restriction; the final repair …
