Dryer
Code E1
low severity
Zanussi models: Zanussi condenser dryers have a primary lint filter in the door opening and a secondary condenser filter in the lower plinth. Clean the plinth filter monthly. Vented models have only the door filter.
Common causes
- Thermistor (temperature sensor) has failed open or short
- Thermistor wiring connector loose
- Thermal fuse blown due to a prior overheating event
Step-by-step fix
- Unplug the dryer.
- Locate the thermistor — usually on the exhaust duct inside the back panel.
- Test resistance with a multimeter: a typical thermistor reads around 10–50 kΩ at room temperature.
- Inspect the thermal fuse (one-shot fuse on the exhaust housing) — it reads 0 Ω if good, open if blown.
- Replace whichever component tests faulty.

Prevention
- Keep the exhaust duct clear.
- Replace the thermal fuse and thermistor together if either has failed — they are inexpensive.
When to stop DIY
If the thermal fuse is blown, also find and fix the root cause (restricted airflow, failed cycling thermostat) before replacing it — it will blow again otherwise.
