Klarstein air conditioner leaks water onto the floor from the front or rear of the unit.

Safety: Unplug the unit before tilting or opening. Water and electricity are a dangerous combination.

Steps:

• Level check: Ensure the unit is level (or slightly tilted toward the drain outlet for window units) using a spirit level.
• Drain cleaning: Remove the front/rear cover to access the condensate tray and drain outlet. Use a flexible brush or pipe cleaner to clear slime and debris from the drain hole and channel.
• Flush drain: Pour a small amount of warm water mixed with a little vinegar through the drain channel to flush it out. Catch water at the drain outlet.
• Drain hose: If a hose is attached, disconnect and blow through it or flush with water to remove clogs. Ensure it slopes downward with no kinks.
• Inspect pan: Check the plastic drain pan for cracks. If cracked, replace the pan or seal temporarily with waterproof epoxy (replacement is preferred).
