Safety first: Unplug the unit before touching internal components.

• Check installation clearance: Ensure the sides and back are not pressed tightly against cabinets or walls. Provide a small gap to prevent vibration transfer.
• Tighten panels: Tighten any loose screws on side, rear, and front panels that may rattle.
• Inspect compressor mounts: Access the compressor area and verify rubber grommets are intact. Replace if hardened or cracked.
• Secure pump: Ensure the circulation and drain pumps are firmly mounted and not contacting metal panels.
