What should I do if the display screen on my Dreame Air Purifier malfunctions? (e.g., it doesn't turn on or goes blank when rotating)

 If you are experiencing issues with the display screen, please follow these troubleshooting steps to diagnose the problem.

Step 1: Perform a Power Cycle

This can often resolve temporary software or power-related glitches.

1. Unplug the device from the wall outlet.
2. Wait for 1-2 minutes to allow the internal components to fully discharge.
3. Plug the power cord firmly back in and attempt to turn the device on.

Step 2: Test the Core Functionality

This step helps determine if the issue is with the screen only or the entire unit.

1. Using either the physical remote control or the Dreamehome app, try to change the purifier's mode or adjust the fan speed.
2. Observe if the purifier responds to these commands (e.g., you can hear the fan speed change).

Step 3: Contact Customer Support

If the screen remains non-functional after the power cycle, it likely indicates a hardware issue.

1. Please contact our customer support team for further assistance.
2. When you contact us, please inform them of the results from Step 2. Knowing whether the purifier still operates via the app or remote is crucial information that will help our team provide a faster and more accurate solution.

Important: For your safety, do not attempt to disassemble or repair the device yourself.
