Wine cooler displays H1 and the internal temperature is too high; bottles feel warm.

Safety first: Unplug the wine cooler before cleaning or accessing the rear compartment. Do not attempt to open the sealed refrigeration system.

Steps to address H1:

• Check ambient conditions: Ensure the cooler is installed in a room within Hoover's specified temperature range and has adequate ventilation around the sides and rear.
• Clean condenser coils: Remove the rear lower panel (if fitted) and use a soft brush and vacuum to remove dust from the condenser coil. Blocked coils greatly reduce cooling efficiency.
• Verify condenser fan operation: With the unit powered (briefly), check that the condenser fan runs when the compressor is on. If not, unplug and inspect the fan for obstructions or damage. Replace the Hoover-compatible condenser fan motor if it does not run.
• Check compressor: When powered, the compressor should hum and vibrate slightly. If it is hot and not running, suspect a failed start relay/PTC or compressor fault (see E5).
• Monitor temperature: After cleaning and verifying fans, allow 12–24 hours for the temperature to stabilize. If H1 persists and the unit does not cool, there may be a refrigerant leak or internal blockage, which requires a certified refrigeration technician.
