Unit stops with E8; may occur during heavy load or high ambient temperature.

Safety first: Isolate power before cleaning or working near the outdoor fan. Do not bend refrigerant pipes.

Steps:

• Clean condenser coil: Remove leaves, dust, and debris from the outdoor coil using a soft brush and low-pressure water. Avoid spraying directly into the electrical compartment.
• Check outdoor fan: With power restored briefly, observe if the fan starts and runs at normal speed. If it does not start or is slow, turn power off and inspect the fan motor and capacitor (on non-inverter models).
• Clearances: Ensure at least the manufacturer-recommended clearance (typically 30–50 cm on sides and 1 m above) around the outdoor unit for proper airflow.
• Refrigerant issues: If E8 persists after cleaning and fan verification, the system may be overcharged or have non-condensable gases. This requires a licensed technician to recover, evacuate, and recharge the system according to Blaupunkt specifications.
