Fisher & Paykel Dryers HC1 Error: HP condenser overheat fault
Fisher & Paykel dryer error code HC1 is a high-severity fault meaning Heat-pump condenser high-temperature fault. Do not restart the dryer while HC1 is displayed. If HC1 was caused by a blocked condenser filter or high ambient temperature, cleaning the filter, allowing 30 minutes of cooling, and power-cycling will clear the code.

Answer to continue safely
Is it safe to keep using?
No. Do not restart the dryer while HC1 is displayed. Operating a heat pump dryer with a blocked condenser or failing compressor can cause permanent refrigerant circuit damage. Allow full cooling, clean the condenser filter, and confirm room temperature before attempting a restart.
Can I reset the code?
Yes. If HC1 was caused by a blocked condenser filter or high ambient temperature, cleaning the filter, allowing 30 minutes of cooling, and power-cycling will clear the code. If HC1 returns within one cycle after cleaning and cooling, a refrigerant or compressor fault is likely and professional diagnosis is required.
When to stop immediately?
Stop if you notice: HC1 returns within 30 minutes of a cleaned-filter restart, Unusual clicking or rattling from the compressor area.
Symptoms You May Notice
HC1 displayed — cycle stopped
The dryer halts mid-cycle and displays HC1. The heat pump compressor is shut down immediately when this code appears.
Cabinet is hot to the touch on the lower rear
The condenser unit at the rear-lower section of the DH series cabinet is abnormally hot, indicating heat rejection is impaired.
Drying takes much longer than normal
Before HC1 triggers a full shutdown, the heat pump runs at reduced efficiency, significantly extending cycle times.
Possible Causes
Blocked condenser air passages
Lint and fluff have accumulated in the condenser air passages at the base of the DH dryer, reducing the airflow needed to reject heat from the refrigerant circuit.
DIY PossibleCondenser fan failure
The condenser cooling fan has failed, preventing airflow across the condenser coil fins and causing refrigerant pressure to rise.
Requires ProfessionalRefrigerant low pressure or leak
Refrigerant loss from the closed-loop heat pump circuit reduces cooling capacity and causes the compressor to overheat.
Requires ProfessionalHigh ambient temperature
Operating the dryer in a room exceeding the maximum rated ambient temperature (typically 35°C) prevents adequate heat rejection and can trigger HC1 during summer or in warm utility rooms.
DIY PossibleSafe Checks You Can Do
-
1
Allow the dryer to cool fully
Leave the dryer door open and the unit unplugged for at least 30 minutes before any inspection. The heat pump compressor must not be restarted while hot.
Restarting a heat pump compressor that is still hot risks compressor damage and may cause the HC1 fault to recur within minutes.

2
Clean the condenser filter and base vents
Fisher & Paykel DH series condenser dryers have a secondary lint filter at the base of the cabinet in addition to the primary drum lint filter. Remove and clean both. Also vacuum any lint from the ventilation slots at the base of the cabinet.
The condenser filter on DH series dryers should be cleaned every 5–10 cycles — more frequently than the primary lint filter. Neglecting it is the leading cause of HC1 on these models.

3
Check room temperature
Confirm the room where the dryer is installed is below 35°C (95°F). In hot weather or unventilated utility rooms, the dryer may need to be relocated or the room ventilated before it can operate without triggering HC1.
Fisher & Paykel DH series heat-pump dryers are rated for ambient temperatures of 5°C–35°C. Outside this range, heat pump efficiency and compressor protection both suffer.
When to Call a Professional
Contact a qualified technician if:
- Refrigerant circuit leak or low charge — requires certified refrigerant handling
- Condenser fan motor has failed
- Compressor has sustained damage from repeated overheat events
