Why Is My Dishwasher Not Drying Properly?
You open the door, the cycle is finished, but the plates are still wet and the plastics are dripping. If your dishwasher isn’t drying as expected, there’s usually a clear cause—often simple to fix. This guide explains what’s happening inside the machine and how to get reliably dry results again.
Most models remove moisture using gentle heat and airflow, or by a process called condensation drying Moist air cools on the stainless-steel walls, turning into water that drains away. It works best with rinse aid and space between items. . Below, you’ll find the most common reasons for poor drying and the quickest fixes.
Common Reasons Your Dishwasher Isn’t Drying
Several everyday issues can reduce drying performance. Start with these quick checks before assuming there’s a fault.
Overloaded or Poorly Loaded Dishwasher
- Items touch or nest, blocking air circulationWarm air needs clear pathways to evaporate moisture from surfaces. Leave gaps between plates and bowls. and heat flow.
- Large trays on the bottom rack can shield the heating zone and trap moisture above.
- Angle concave items (mugs, bowls) so water drains off rather than pooling.
Rinse Aid Empty or Set Too Low
- Rinse aid reduces water surface tension so droplets sheet off for faster drying.
- Top up the dispenser and set the dosage to medium; increase one step if droplets persist.
- Use quality detergent and keep salt levels correct to prevent filming that holds moisture.
Plastic Items Stay Wet
- Plastic retains less heat than glass/metal, so it evaporates moisture more slowly.
- Place plastics on the top rack and tilt them; open the door at cycle end to vent steam.
Door Doesn’t Open at the End of the Cycle
- Models with auto-door openingA feature that pops the door open slightly at programme end to release steam and speed up drying. vent steam to boost drying.
- If the door doesn’t pop or you disable the chime, steam may stay trapped inside.
- Manually crack the door when the programme finishes to let moisture escape.
Faulty Heating Element, Fan, or Vent

- Persistent foggy steam on opening suggests a fan/vent problem preventing exhaust.
- Listen for the fan near cycle end; silence may point to a failed component.
How to Improve Your Dishwasher’s Drying Performance
Before calling a technician, try these practical steps to help your dishwasher dry dishes more effectively.
- Always use rinse aid and check it’s topped up to the correct level.
- Space items evenly so warm air can circulate freely.
- Angle cups and bowls to let water drain off instead of pooling.
- Place plastics on the top rack away from direct heat for better evaporation.
- Use your dishwasher’s Extra Dry or Intensive Dry function if available.

When It Might Be a Technical Fault
If your dishwasher has always dried well but suddenly leaves everything damp, there could be a mechanical or electrical issue. Below are the most common fault signs and what they mean.
Signs of a Faulty Heating Element
- Dishes and interior surfaces feel cold even immediately after a full cycle.
- Water may not reach proper wash temperatures, affecting cleaning as well as drying.
- The cycle finishes unusually fast, suggesting the heat stage was skipped.
Signs of a Faulty Fan or Vent System
- Visible steam clouds when the door opens, indicating trapped condensation.
- Heavy water droplets forming on the inner door or racks after drying finishes.
- Fan noise missing at the end of the cycle can point to a failed motor or blocked vent.

Preventing Future Drying Problems
A few simple habits can keep your dishwasher drying efficiently for years to come. Regular care ensures heating elements, sensors, and vents continue to perform at their best.
- Clean filters and spray arms monthly to maintain strong water flow and even heating.
- Keep the rinse aid dispenser topped up and salt levels balanced to prevent residue buildup.
- Avoid overloading or blocking vents so air can circulate freely around dishes.
- Run an empty cycle with a dishwasher cleaner once a month to remove grease and limescale.
- Leave the door ajar after each cycle to release moisture and protect seals from mould.
