# Frigidaire dishwasher not drying

### What to do in the next ten minutes

Check the rinse aid reservoir and fill it — this is the single commonest answer and it is free. Then run a normal cycle and open the door as soon as it finishes: if the tub is hot and steamy, the machine made heat and the moisture had nowhere to go, which points at the vent rather than the heater.

### Condensation drying, explained once

Machines that do not have a fan rely on the load being hot at the end of the rinse: water evaporates from hot china and condenses on the cooler stainless tub wall, where it runs down and drains away. Plastic has almost no thermal mass, so it cools before its water evaporates and stays wet. That is physics rather than a defect, and it is why the same machine dries a plate perfectly and a storage box badly.

### Why rinse aid does what a hotter cycle cannot

Rinse aid lowers the surface tension of the water so it sheets off surfaces instead of beading on them. Less water on the load at the end of the rinse means less to evaporate and fewer spots where it dries. On a condensation-dry machine it is not an optional extra — it is part of how the drying works, and running without it produces exactly this complaint on a mechanically perfect appliance.

The rinse aid is empty

Water beads instead of sheeting off and stays on the load. Owners often switch to all-in-one tablets and stop filling it, which is when this complaint starts.

The vent flap is not opening

The moisture cannot leave the tub. The dishes are wet and the tub is warm, which is the pattern to report.

The heating element or its thermostat

The final rinse never gets hot enough to leave anything dry. Everything comes out wet, china included, and the tub is not warm at the end.

Fill the rinse aid and run one cycle

The cheapest test on this page and it settles a good share of them.

Feel the tub the moment it finishes

Hot and wet is a venting story; cool and wet is a heating one.

Note whether plastics only are wet

That is the design answer rather than the repair answer.

Everything is wet at the end, plastics worst of all

What it usually means

Damp plastic on the plainer machines is the design, not a failure

Rinse aid changes drying more than any setting on the panel

Wet china as well as wet plastic is the version worth a visit

### I use all-in-one tablets. Do I still need rinse aid?

On these machines, yes, and it is the commonest cause we find. The rinse aid in a tablet is released with the wash, not at the final rinse where it is needed.

### Can the drying be improved another way?

Opening the door a couple of inches as soon as the cycle ends lets the steam out and dries the load in minutes. It is not elegant and it works.
