What E303 means
Error E303 on many Candy dryer models is used as a generic fault code. It usually points to a problem detected by the control board, such as a sensor reading outside the expected range or a cycle that could not complete.
Common causes
- Temporary software glitch or power fluctuation
- Blocked filter, hose or internal passage
- Sensor or wiring connection not making good contact
Quick checks you can do yourself
- Turn the appliance off at the mains and leave it powered down for a few minutes.
- Check and clean accessible filters, drains and hoses for blockages.
- Inspect the door or lid area for obstructions preventing a good seal.
- Restart a short cycle and monitor the appliance to see if the error returns.
Always unplug the appliance and switch off power at the mains before removing panels or working near wiring or water connections.
When to call a professional
If error E303 reappears after simple checks and a power reset, there could be an internal electronics or sensor fault. At that point it is safer to have a qualified engineer test the appliance rather than replacing control boards or wiring blindly.
Recommended next steps
If the appliance continues to work normally after a reset and cleaning, keep an eye on it for a few days. If the same error appears frequently or is accompanied by unusual noises or smells, stop using the appliance and arrange a professional inspection.
Typical repair cost
£0–£180. Vent and filter cleaning is often free. If a heater, thermostat, or belt is needed, parts and fitting often come in around £110–£180.
How to prevent this error in future
- Clean the lint filter after every load and keep the condenser (if fitted) clean.
- Ensure good airflow: avoid crushed vent hoses and clean external vents.
- Do not overload; heavy loads can strain belts and bearings.
- Run an occasional maintenance clean to reduce lint build-up inside the cabinet.
