# An Asko Dryer That Will Not Dry: Three Filters, In Order

A program that runs its full length and leaves the washing damp. On a vented dryer that would be heat or a crushed duct. On these machines it is almost always the air path, and three of the checks cost nothing.

## Why nothing leaves the room

A condenser dryer takes damp air from the drum, cools it until the moisture drops out, warms it again and sends it back round. A heat pump machine does the same thing more efficiently. Either way no air leaves the building, which is why these live happily in a closet with no external wall — and why every filter matters more than it would on a vented machine. There is no duct carrying problems away.

## The three filters, in order

**The water container.** Empty it and push it fully home. A container left half-seated reads as full, and a machine that believes it has nowhere to put the water stops before it starts.

**The door lint filter.** Pull it, rinse it under a tap, and dry it before it goes back. A wet filter blocks airflow as effectively as a clogged one, and people routinely refit them dripping.

**The condenser filter.** Open the plinth at the bottom front of the machine. Behind it is a filter or a block that pulls out. Wash it until the water runs clear — not tapped out over a bin. On a machine that has never had this done, doing it once is often the entire repair.

## Then the sensor bars

Inside the drum are two metal strips that measure how wet the laundry is by conductivity. Fabric softener leaves a film on them that is invisible and quite enough to make the machine read a wet load as dry and end the cycle early. Clean them back to bare metal with a little vinegar on a cloth.

## Then, and only then, heat

If the air path is genuinely clear and the sensors are clean and the load is still damp, the heating side is the answer. What that means depends on the machine: on a condenser model it is a heater and its thermostats, which are ordinary parts; on a heat pump model there is no element at all, and the sealed refrigeration circuit is a different order of cost. The model number decides which conversation you are having.

## What this climate does to the interval

The service intervals in the manual assume a temperate laundry room. An interior closet here sits at high humidity for months, and the filters load in proportion to how much moisture the machine is moving. Twice a year on the condenser is realistic locally. The machines that reach fifteen years are the ones where somebody did that instead of waiting for a cycle that never ended.
