Tumble Dryer Taking Too Long To Dry

Blocked Lint Filter

The most common cause. Even a partially blocked filter significantly restricts the airflow needed for efficient drying. The lint filter must be cleaned after every single drying cycle without exception.

Blocked Condenser (condenser and heat pump dryers only)

A clogged condenser reduces efficiency dramatically. On heat pump dryers in particular, a dirty condenser can more than double drying times. Clean the condenser regularly according to your manual.

Dirty Humidity Sensors

The humidity sensors monitor moisture in the drum and determine when laundry is dry. If coated with fabric softener residue they give inaccurate readings and cause the machine to run longer than necessary. Wipe them regularly with a damp cloth.

Overloaded Drum

Too many items prevent clothes from tumbling freely and restrict airflow inside the drum. The drum should be no more than two thirds full for most drying programmes.

Laundry Too Wet Going In

If the washing machine has not completed an adequate spin cycle, laundry will be much wetter than normal and will take significantly longer to dry. Run an extra spin cycle first.

Blocked Exhaust Duct (vented dryers only)

A kinked or partially blocked exhaust duct slows the removal of moist air from the machine, extending drying times considerably. Check and clean the duct regularly.

Wrong Programme Selected

Using a lower heat setting or shorter timed programme than required for the load size or fabric type will result in extended drying times or damp laundry at the end of the cycle.

Clean the Lint Filter

Remove the lint filter and clean it thoroughly. Rinse under water if needed and allow to dry completely before refitting. Do this after every single cycle.

Clean the Condenser

Remove the condenser unit, rinse it thoroughly under cold running water until the water runs clear, allow it to dry completely and refit firmly.

Wipe the Humidity Sensors

Wipe the two metal sensor strips on the inside of the drum with a clean damp cloth to remove any fabric softener residue affecting their readings.

Empty the Water Tank

Pull out the condensate water tank, empty it fully and refit it firmly before starting the cycle.

Reduce the Load Size

Try drying a smaller load to see if times improve. If they do, overloading was the cause. The drum should be no more than two thirds full.

Check the Exhaust Duct

Inspect the exhaust duct for any kinks or blockages. Clean out any lint build-up inside the duct to restore full airflow through the machine.
