Last updated: 4 September 2026
Quick Answer
Clean the lint filter, check the condenser, and check the heating element.
Overview
A tumble dryer leaving clothes damp is frustrating. This guide covers diagnosing and fixing the issue.
Step-by-Step Fix
Safety & Preparation
Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).
- Before you begin any inspection or repair, always switch off your tumble dryer at the mains power socket and then unplug it completely. This crucial safety step prevents electric shock and ensures the appliance cannot accidentally switch on while you're working on it.
- Locate the lint filter, usually found just inside the door opening, and pull it out gently. Remove all accumulated lint, fluff, and debris by hand or with a soft brush, and rinse the filter under a tap if necessary to clear any blockages before reinserting it.
- For condenser or heat pump dryers, locate the condenser unit, typically behind a flap at the bottom front of the machine, and unlatch it according to your manual. Carefully slide out the condenser and rinse it thoroughly under a running tap to remove any clogged lint, ensuring all fins are clear before reinserting it securely.
- With the dryer unplugged, carefully access the heating element compartment, usually at the rear, and use a multimeter set to ohms to test the element's continuity across its terminals. If the multimeter shows an open circuit (no reading or infinite resistance), the heating element is likely faulty and requires replacement.
- Still with the dryer unplugged, locate the thermostats and thermal fuses, often mounted on or near the heating element housing, and test each one individually for continuity using a multimeter. A lack of continuity across any of these components indicates a blown fuse or a faulty thermostat, which will prevent the dryer from heating.
- If the dryer still leaves clothes damp, try running a much smaller load of laundry than usual to see if the drying performance improves. Overloading the drum restricts airflow, preventing efficient heat distribution and moisture removal, which can lead to clothes remaining damp.
