Step-by-Step DIY Fix Guide
- SAFETY: Unplug the dryer.
- Remove and clean the lint filter thoroughly.
- Check the exhaust vent hose is not kinked or blocked.
- Perform a hard reset: unplug 10 minutes (allows thermal cut-out to reset if tripped), reconnect.
- Run a short timed cycle with a small load.
- If E4 returns, contact Fisher & Paykel service.
If the warning comes back after restart
- If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
- If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
- E4 returns after cleaning the lint filter and 10-minute reset
What This Error Means
The E4 fault code on your Fisher & Paykel Dryer means: 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. Also displayed as Err4 on some models.
Most common cause: blocked lint filter causing heater to overheat and trip the thermal cut-out.
Contact Fisher & Paykel service if E4 returns after cleaning the filter and 10-minute reset.
Most Likely Cause by Symptom
The Fisher & Paykel dryer may stop, pause, or refuse to complete the cycle normally.
Likely cause: Blocked lint filter causing heater to overheat and trip the thermal cut-out
Check first: SAFETY: Unplug the dryer.
Performance may drop because airflow, filtering, or draining is restricted.
Likely cause: Heating element failure
Check first: Remove and clean the lint filter thoroughly.
The warning may return immediately because the appliance is detecting an internal fault.
Likely cause: Thermal cut-out tripped
Check first: Check the exhaust vent hose is not kinked or blocked.
Common Causes
- Blocked lint filter causing heater to overheat and trip the thermal cut-out
- Heating element failure
- Thermal cut-out tripped
- Temperature sensor fault
What Not to Do
- Do not run the dryer with a full or partially blocked lint filter
Model and Display Variation Notes

When Not to Keep Troubleshooting

How to Prevent It Recurring
- Clean the lint filter after every single load — a partially blocked filter is the leading cause of heater faults
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.
E9
The heater thermistor (temperature sensor for the heating element circuit) has reported a fault. This requires professional diagnosis.
E6
The dryer has detected restricted airflow due to a blocked lint filter. Clean the filter and the code will clear. A blocked lint filter is a leading cause of dryer fires.
