Step-by-Step DIY Fix Guide
- SAFETY: Unplug the dryer.
- Clean the lint filter.
- Perform a hard reset: unplug 5 minutes, reconnect, and test.
- If E9 returns, contact Fisher & Paykel service.
If the warning comes back after restart
- If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
- E9 persists after cleaning filter and 5-minute reset
What This Error Means
The E9 fault code on your Fisher & Paykel Dryer means: The heater thermistor (temperature sensor for the heating element circuit) has reported a fault. This requires professional diagnosis. Also displayed as Err9 on some models.
Most common cause: heater thermistor failure.
Contact Fisher & Paykel service if E9 persists after a filter clean and reset.
Most Likely Cause by Symptom
The Fisher & Paykel dryer may stop, pause, or refuse to complete the cycle normally.
Likely cause: Heater thermistor failure
Check first: SAFETY: Unplug the dryer.
Performance may drop because airflow, filtering, or draining is restricted.
Likely cause: Wiring fault to thermistor
Check first: Clean the lint filter.
The warning may return immediately because the appliance is detecting an internal fault.
Likely cause: Control board fault affecting thermistor reading
Check first: Perform a hard reset: unplug 5 minutes, reconnect, and test.
Common Causes
- Heater thermistor failure
- Wiring fault to thermistor
- Control board fault affecting thermistor reading
What Not to Do
- Do not run the dryer with a heater thermistor fault

When Not to Keep Troubleshooting
E9 persists after cleaning filter and 5-minute reset
How to Prevent It Recurring
- Keep the lint filter clean — sensor faults are often triggered by heat stress from blocked airflow
Related Error Codes
E3
The exhaust temperature thermistor has reported a reading outside the expected range. The dryer cannot monitor exhaust temperature — a safety-critical function.
E4
The heating system has reported a fault — either the heater element, thermal cut-out, or a temperature sensor. A blocked lint filter often causes this code by forcing the heater to overheat.
