Bush heat pump dryer shows E08 and does not heat properly; cycle may run but clothes stay damp.

Safety first: Unplug the dryer. Heat pump systems contain refrigerant under pressure; do not open sealed refrigeration components yourself.

• Clean all filters and coils: Remove and clean the lint filter and any secondary filters. Access the heat pump coil (often behind a lower front or rear panel) and gently vacuum lint from the fins without bending them.
• Ensure adequate ventilation: Make sure the dryer has sufficient space around it for air circulation. Blocked vents can cause overheating and trigger E08.
• Listen for compressor operation: With panels reinstalled, plug in and start a cycle. After a few minutes, listen for the compressor starting (a low humming sound). If it never starts, the compressor, relay, or capacitor may be faulty.
• Check visible wiring: Inspect wiring to the compressor and associated sensors for damage or loose connectors. Do not disturb sealed pipework.
• When to call a professional: If cleaning and basic checks do not clear E08, the issue is likely within the sealed heat pump system (compressor, refrigerant charge, pressure sensors). This requires a qualified refrigeration engineer or authorised Bush service technician.
