Possible Causes
Failed compressor, Blocked evaporator or condenser coil, Faulty compressor start relay, Low refrigerant charge (leak in sealed system)
How to Fix / Troubleshooting
Safety first: Unplug the dryer. The heat pump system is a sealed refrigerant circuit; only certified technicians should open or recharge it.
- Clean air paths: Remove and clean the lint filter. Pull out the lower front cover to access the heat exchanger (if user-accessible). Rinse the heat exchanger fins with lukewarm water and allow to dry completely before reinserting.
- Inspect evaporator and condenser (if accessible): With panels removed, visually check the coils for heavy lint buildup. Use a soft brush and vacuum to gently clean the fins without bending them.
- Listen for compressor operation: During a test run (with panels safely in place), listen for the compressor starting a few minutes after the cycle begins. A complete lack of compressor noise may indicate a failed compressor, relay, or control board.
- Check compressor relay and wiring: With power off, inspect the compressor start relay and wiring harness for signs of overheating or loose connections. Reseat connectors.
- When to call a professional: If E08 persists after cleaning and basic checks, or if you suspect a refrigerant leak, failed compressor, or sealed system issue, contact an authorized Amica service center. Do not attempt to open the sealed system yourself.
