Condenser tumble dryers are popular in UK homes because they don’t require an external vent. Instead, they collect moisture in a reservoir. While convenient, these machines have their own common faults that can affect performance and increase repair costs.
Common problems with condenser dryers
Because they use an internal condensation system, condenser dryers often develop issues not seen in vented models. Typical problems include:
- Clogged condenser unit
- Blocked water reservoir or drain
- Faulty heating element
- Defective fan or pump
- Moisture sensor failures
- Control board errors
Even small blockages can reduce drying efficiency and increase wear on internal components.
Repair process
Engineers usually start by cleaning the condenser unit and water reservoir. They then test airflow and heating performance. Sensors are checked to ensure the dryer is detecting moisture correctly. Finally, electrical components are tested.
Some condenser issues, such as a broken pump or fan, require more labour because components are harder to access than in vented machines.
Typical UK repair costs
- Condenser cleaning and service: £60 to £100
- Heating element replacement: £110 to £190
- Fan motor replacement: £120 to £220
- Moisture sensor replacement: £70 to £130
- Control board replacement: £160 to £320
- Call-out fee: £40 to £70
Most repairs for condenser faults fall between £90 and £200.
Signs your condenser dryer needs repair
- Clothes remain damp after a full cycle
- Water reservoir fills unusually fast or slow
- Unusual noises during drying
- Warning lights or error codes
- Overheating or tripping the fuse
Is it worth repairing?
If your dryer is under 7–8 years old, condenser repairs are usually cost-effective. Cleaning and minor parts replacement restore efficiency. Older machines may see repairs approaching replacement costs.
