Question 1

How to reset the DUUX North?

Accepted Answer

The DUUX North manual does not describe a complete software reset procedure (factory reset). However, here are the available restart and reset steps:

Reset the Wi-Fi connection

Press and hold the power button until the Wi-Fi indicator starts blinking again. This exclusively resets the wireless settings.

Restart the device

Unplug the air conditioner from the power outlet, wait at least 3 minutes (to protect the compressor), then plug it back in. This restart may resolve minor malfunctions.

If the problem persists

If your DUUX North displays an error code (E0, E1, E2, E3, E4) or is not functioning properly, contact the manufacturer's support. Codes E0, E1, and E3 indicate a sensor failure; E2 and E4 signal a full water tank.

Question 2

Why won't my DUUX Beam humidifier turn on while the remote control lights up red and the Beam's screen remains off?

Accepted Answer

If your DUUX Beam humidifier shows the red power/water indicator and the screen remains off, it most likely indicates that the water level in the tank is insufficient. This is the most common cause of this specific symptom. The Beam's safety system prevents the device from starting when there is not enough water to generate mist.

Immediate solution: Start by checking and filling the water tank. Here is the exact procedure: first unplug the power cord, then remove the transparent top cover. Fill the tank with clean water up to the MAX level indicated on the cover (do not exceed this level). Replace the cover and ensure it is securely locked. Then plug the power cord back into the outlet - the screen should light up and display the normal status. You can then turn on the device via the remote control.

If after filling the device still does not work and the indicator remains red, check the following power points: ensure that the power plug is fully inserted into the electrical outlet (push it all the way in), check for a power outage by testing another device on the same outlet, and test another electrical outlet to rule out a fault with the initial outlet.

Next, check the installation of the tank: remove the water tank and reinstall it correctly on the base of the device - a misaligned tank can also prevent operation. The screen will display an E2 notification if the tank is not properly placed.

Regarding the remote control showing a red light, it is possible that the batteries are weak. Replace them with new batteries. However, if the remote control works but the Beam does not execute the commands, the problem usually lies within the device itself - always check first that the device has enough water and is properly powered.

If after checking the water level, electrical connection, and tank installation the device still does not turn on and continues to show the red indicator, a technical issue may be at fault. In this case, contact DUUX customer service as the device may require professional repair.
