Step-by-Step DIY Fix Guide
- SAFETY: Unplug the dryer.
- Clean the lint filter thoroughly.
- Check the exhaust vent hose is not kinked or blocked.
- Perform a hard reset: unplug 5 minutes, reconnect, and test.
- If E3 returns, contact Fisher & Paykel service.
If the warning comes back after restart
- If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
- If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
- E3 persists after filter cleaning and vent check
What This Error Means
The E3 fault code on your Fisher & Paykel Dryer means: The exhaust temperature thermistor has reported a reading outside the expected range. The dryer cannot monitor exhaust temperature — a safety-critical function. Also displayed as Err3 on some models.
Most common cause: thermistor failure.
Contact Fisher & Paykel service if E3 persists after checking filter and vent.
What users usually notice before this code
Fisher & Paykel dryer warnings like this usually appear after airflow restriction, repeated lint buildup, interrupted heating, or a cycle that stops without returning to normal drying.
Common misdiagnoses
- Assuming the display code proves one exact failed part before the safe first checks are done.
- Replacing a lock or latch too early when alignment, trapped laundry, or startup conditions may still explain the warning.
- Treating a sensor-related warning as a guaranteed board failure before checking the simpler model-family causes first.
Most Likely Cause by Symptom
The Fisher & Paykel dryer may stop, pause, or refuse to complete the cycle normally.
Likely cause: Thermistor failure
Check first: SAFETY: Unplug the dryer.
Performance may drop because airflow, filtering, or draining is restricted.
Likely cause: Thermistor wiring disconnected
Check first: Clean the lint filter thoroughly.
Common Causes
- Thermistor failure
- Thermistor wiring disconnected
- Blocked exhaust vent causing abnormal temperature readings
What Not to Do
- Do not run the dryer when exhaust temperature cannot be monitored — overheating risk
Model and Display Variation Notes
Model-family notes
- Fisher & Paykel dryer display wording and code formats can vary by series.
- If your model behaves differently, check the owner manual before trying any deeper maintenance step.
- Some models may display the same fault as E3, Err3.
Display and panel differences
- Some control panels show this issue as E3, Err3 instead of only E3.
- Panel wording and whether the code appears with letters, numbers, or a longer variant can differ by model family.
Parts, Tools and Service Options
Service option
Fisher & Paykel service visit if the warning returns after the basic checks are complete.
Manual and model check

Common parts
- Exhaust thermistor (~$15–$40) (varies) - consult technician
This section stays service-first because the page points more strongly toward support or professional repair than a routine parts purchase.
When Not to Keep Troubleshooting
E3 persists after filter cleaning and vent check
How to Prevent It Recurring
- Clean the lint filter after every load and inspect the exhaust vent annually
Related Error Codes
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.
E9
The heater thermistor (temperature sensor for the heating element circuit) has reported a fault. This requires professional diagnosis.
