What does code E5 mean of a Hisense portable AC?

Answered by Phillip Nicastro

The E5 error code on a Hisense portable AC unit indicates that the unit needs to be drained. This error occurs when the water level in the unit’s internal reservoir reaches a certain point. To resolve the issue, you will need to drain the water through the drain port located at the back of the unit.

To drain the water, follow these steps:

1. Turn off the portable AC unit and unplug it from the power source. It is important to ensure that the unit is not connected to any electrical supply before performing any maintenance.

2. Locate the drain port at the back of the unit. It is usually a small opening with a screw or a cap.

3. Prepare a container or a tray that can hold the water being drained. Place it underneath the drain port to catch the water.

4. Unscrew the cap or remove the screw from the drain port to open it. Be careful not to lose the screw or cap as you will need it later.

5. Allow the water to drain completely into the container or tray. Depending on the amount of water accumulated, this process may take a few minutes. Ensure that the container or tray is large enough to hold all the water to avoid any spillage.

6. Once all the water has drained, replace the cap or screw on the drain port securely. Make sure it is tightly closed to prevent any water leakage.

7. Plug the portable AC unit back into the power source and turn it on. The E5 error code should no longer appear, and the unit should start running normally.

It is important to regularly check and drain the water from the portable AC unit to prevent the water reservoir from overflowing. This is especially crucial during periods of high humidity or when the unit is running for extended periods.

Additionally, ensure that the drain port is clear of any debris or blockages that could hinder the drainage process. Regular maintenance and cleaning of the unit will help prevent any issues related to water accumulation.

To summarize, the E5 error code on a Hisense portable AC unit indicates that the unit needs to be drained. By following the steps outlined above, you can resolve this issue and ensure the proper functioning of your portable AC unit.
