Air Conditioner 20

When the sweltering summer heat strikes, an air conditioner is a saving grace. However, like any other appliance, it requires regular maintenance to function optimally. One of the most common maintenance tasks is emptying the water from your DeLonghi Air Conditioner. Here is an in-depth guide on how to do it safely and effectively.


To empty water from a DeLonghi Air Conditioner, first turn off and unplug the unit. Locate the drain hose typically at the back of the unit, and remove the cap. Place a container under the drain hose to catch the water or use a garden hose to direct the water elsewhere. After draining, replace the cap on the drain hose. It’s recommended to do this at least once a month or more frequently in very humid conditions.

Understanding Your DeLonghi Air Conditioner

Before we delve into the process, it’s important to understand your air conditioner. DeLonghi Air Conditioners are designed with a drainage hose located on the back of the unit, usually near the bottom or in the middle. Some models have a self-evaporative system that eliminates the need for frequent draining, but in a humid environment, you may still need to drain the water manually.

Signs Your DeLonghi Air Conditioner Needs Draining

Knowing when to drain your air conditioner is crucial. Some telltale signs include the unit shutting down when the tank is filled to prevent overflowing and the need to drain the unit before restarting. Some DeLonghi models also have an indicator light on the control panel that flashes when condensation drainage is needed.

Here is a step-by-step guide on how to empty water from your DeLonghi Air Conditioner:

  1. Turn off the unit: Always turn off your air conditioner and unplug it from the power source before draining the water.
  2. Locate the drain hose: It’s typically at the back of the unit, near the bottom or in the middle.

  4. Drain the unit: Place a container under the drain hose and let the water flow out. You can also use a garden hose to direct the water to a suitable location.

Remember to drain your DeLonghi Air Conditioner at least once a month, or more frequently in extreme humid conditions.

  4. Clean the external body: Use a damp cloth. Do not use solvents or cleaning products.
