Dryer shows E08 and may not heat properly; often associated with heat pump system issues on heat pump models.

Safety first: Disconnect power before removing panels. Do not attempt sealed system refrigerant repairs yourself.

E08 on Blomberg heat pump dryers points to a problem in the heat pump circuit.

• Clean air paths: Remove and clean the lint filter and condenser filter. Access the evaporator/condenser area (usually behind a lower front or side panel) and gently vacuum lint from the fins using a soft brush attachment.
• Check circulation fan: Locate the heat pump fan motor and ensure the fan blades spin freely and are not obstructed by lint or debris. If the fan is seized or noisy, replace the fan motor assembly.
• Listen for compressor operation: During a cycle, the compressor should start after a short delay and produce a low humming sound. If it never starts, or starts then trips, there may be a compressor or control issue.
• Inspect wiring and connectors: Check harnesses to the compressor, fan, and related sensors. Reseat any loose connectors.
• Sealed system issues: If the dryer runs but never heats properly and E08 persists despite clean airflow and a working fan, the heat pump may be low on refrigerant or have a compressor fault. These are sealed system repairs that must be performed by a qualified refrigeration technician.
