The belt wraps the drum and the motor pulley. It breaks with age or when the drum is overloaded, and the symptom is a motor that runs with a drum that does not turn.

Washer-Dryer Combo Repair: When One Cycle Does Both
Diagnose a washer-dryer combo or laundry center that won't dry, drains slowly, smells musty or locks the door. Check the ventless condenser and drain system.
A washer-dryer combo shares one drum, one motor and one control board between two jobs, so a fault in the drain or airflow system shows up as a drying failure. Ventless condenser combos dry by heating air and condensing the moisture with cold water — a clogged condenser, a weak drain or a scaled water path makes clothes come out hot and damp.
Stacked laundry centers are two separate machines in one cabinet, and each half is diagnosed on its own. In both layouts, check the drain pump and filter before the heating circuit: on a combo, the machine will not dry properly if it cannot shed water.
Symptoms this guide covers
- Clothes are warm but still damp after the dry cycle
- Cycle takes far longer than the display suggests
- Water left in the drum or a drain error
- Musty smell after drying
- Door stays locked after the cycle ends
- Lint buildup inside the drum or on the door glass
Test order before you replace anything
- Clean the drain pump filter and confirm the drain hose is not kinked or partially blocked
- On ventless models, clean the condenser and the condenser housing
- Test the heating element or heat pump and the blower for airflow
- Check the door lock and the water level pressure switch
- Run a rinse-and-spin cycle and confirm the drum empties completely before testing the dry cycle
Parts involved in washer-dryer repair
The thermal fuse is a one-shot safety device on the exhaust path. It opens when the dryer overheats, which is why replacing it without clearing the lint blockage leads to a repeat failure.
Electric dryer elements are coiled resistance wire in a metal frame. They break with age or heat cycling, and a broken coil is often visible as a gap or a blistered section.
The drain pump empties the tub before the spin cycle. A blocked pump or a failed motor leaves standing water and stops the cycle, and the machine will not spin while water remains.
The inlet valve controls hot and cold fill. A clogged screen slows the fill; a failed solenoid lets the washer overfill or not fill at all.
The lid switch tells the control the lid is closed before a spin. A failed switch stops the spin and drain on top-loaders even though the machine fills and agitates normally.
The boot seals the door to the tub on a front-loader. Tears and mould cause leaks and odour, and a boot that is not seated correctly will leak on every spin.
Many top-load washers use a belt between the motor and transmission. A glazed, stretched or broken belt causes a drum that will not agitate or spin while the motor runs.
The control board runs the cycle and switches the loads. It is the most over-diagnosed part in appliance repair: failed elements, sensors, switches and pumps cause most 'board' symptoms.
Rigid or semi-rigid duct, clamps and an exterior hood. Replacing crushed flex duct with smooth rigid pipe is often the real fix for long dry times — before any part is changed.
What drives the cost
- Ventless condenser versus vented versus heat-pump drying
- Whether the unit is a true combo or a stacked laundry center
- Access to the drain pump and condenser
- Control board and door lock parts on compact European models
Safety first
- Unplug the combo and shut off the water before opening the cabinet — these units run on 240 V
- Ventless dryers use water for condensing; a blocked drain can scald and flood during a dry cycle
- Do not bypass a door lock; combo drums reach high temperatures and a bypassed lock is a burn and flood risk

Common questions
Why does my washer-dryer leave clothes damp?
On ventless combos, a clogged condenser, a partially blocked drain or a scaled water path is the usual cause. The machine cannot condense moisture if it cannot move water.
How long does a combo take to wash and dry?
A full wash-dry cycle commonly runs three to five hours because the same drum handles both jobs at lower drying capacity. Long cycles are normal; a sudden increase is not.
Can a combo be vented?
Most compact combos are ventless by design and cannot be converted. Vented all-in-one units exist but are uncommon in North America.
Why is there lint inside the drum?
Ventless combos trap lint in the condenser and door area rather than a vent. Clean the condenser, the door glass and the rubber seal regularly.
