Got your Delonghi portable air conditioner to work, but it’s not evaporating water? Here are some quick fixes to help you get the unit working like new again!

Delonghi Portable Air Conditioner Not Evaporating Water

A portable air conditioner’s pump must be primed

In order for the pump to function properly, it must be primed. To prime, the pump, fill the tank with water, and then turn on the power switch.

The pump will start and the water will begin to circulate. If the pump does not start, check the power cord and make sure it is plugged in. If the cord is plugged in, then check the circuit breaker and reset it if necessary.

Check if there is adequate water in the basin

If your portable air conditioner isn’t evaporating water, there are a few things you can check. First, make sure that the unit is turned on and set to the correct mode. Second, check the air filter and clean it if necessary.

Third, check the exhaust hose to make sure it’s not kinked or blocked. Fourth, check the water reservoir to make sure it’s full. Fifth, check the float switch to make sure it’s not stuck in the off position. Sixth, check the condenser coils to make sure they’re clean. Seventh, if all of these things are in order and your unit still isn’t evaporating water, you may need to call a technician for help.

Check if there is water and ice in the AC pump

If your portable air conditioner isn’t cooling, it might not have enough water. The pump in a portable air conditioner circulates water and ice to create cool air. If there’s not enough water, the air won’t be as cold.

You can add water to the reservoir (usually located at the back of the unit) until it’s full. Make sure to use distilled water so that it doesn’t damage the pump. Once you’ve added water, give the unit a few minutes to start circulating it. If it still doesn’t seem to be working, you might need to add more ice.

Your compressor might be damaged

If your DeLonghi portable air conditioner isn’t evaporating water, there are a few things you can do to fix it. First, check the refrigerant line to make sure it’s not empty, damaged, or clogged. If the line is empty, you’ll need to refill it with refrigerant.

If the line is damaged, you’ll need to replace it. And if the line is clogged, you’ll need to clean it out. Second, check the compressor to make sure it’s not overheating. If the compressor is overheating, you’ll need to repair or replace it. Third, check the condenser coils to make sure they’re not dirty or blocked.

Recharge your unit if you haven’t used it in a long time

If you haven’t used your portable air conditioner in a while, it may need to be recharged. This is a simple process that can be done at home. All you need is a charger and an outlet. First, make sure the unit is turned off.

Then, find the charging port and plug in the charger. Once the unit is plugged in, turn it on and let it run until the water evaporates. You may need to do this multiple times if the unit has been sitting for a while.


Some of the questions are asked by people frequently. These are mentioned below.

Is the air filter for AC necessary?

The HVAC system needs to be equipped with a filter in order to perform optimally. Without a filter, the unit is exposed to all kinds of dust and debris that can cause significant, and expensive, problems with the system.

What happens if the AC filter is dirty?

A dirty filter will also result in poor cold airflow in your air conditioner, which will cause ice to form on its coils as a result of the buildup. As soon as that happens, your air conditioner will be unable to function.
