Miele Dryer E1 Error Code: Causes and Fixes
Quick answer: Thermistor value out of range
What you’ll notice
Dryer stops heating or shuts off; thermistor value is outside the expected range.
Miele
Dryer
Code E1
medium severity
Miele models: Miele heat-pump and condenser dryers do not vent externally; condensate drains to a collection tank or a direct-drain connection. The door-opening lint filter is the primary filter, but there is a secondary condenser fluff filter in the lower plinth that must be cleaned monthly. A full condensate tank will pause the cycle without an explicit error.
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.
FAQ
What does E1 mean on Miele dryer?
E1 usually indicates: Thermistor value out of range.
Can I keep using the appliance with E1?
Use caution. Severity is medium. 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.
How long does this fix usually take?
Typical first-pass troubleshooting takes 30–45 minutes.
