Dryer displays E03, poor or no heating

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blocked exhaust duct, Faulty exhaust temperature sensor, Lint buildup on sensor

Safety first: Unplug the dryer before removing ducts or panels.

Clean exhaust path: Remove and clean the exhaust hose and wall vent. Ensure there are no kinks or crushed sections.
Clean internal ducts: Access the internal exhaust duct and remove lint with a vacuum and brush.
Inspect exhaust sensor: Locate the exhaust NTC sensor and clean any lint from around it. Check wiring and connectors.
Replace sensor: If E03 persists, the exhaust sensor may be out of range and should be replaced with an Ariston‑approved part.
