A common fault with the Arete One is for the display to stop working but showing nonsense symbols or in some cases not showing anything at all, but still responding to button presses with beeps. This seems to be caused by the two digit display component which is a very cheap component.

This issue can be diagnosed by the device not performing any of the normal functions of air purification or dehumidification, and the buttons do appear to cause beeps and changes on the display but the normal modes of operation don't cycle while pressing the buttons.

In my case, the device would beep when power was supplied, with a blank display. If I pressed the power button then as long as I held it, the display would show "L!".

I think this was a red herring as there wasn't a particular device fault code in the manual corresponding to that.

Looking at [link|https://www.reddit.com/r/Appliances/comments/1937r57/meaco_dehumidifier_not_working/|this reddit thread|new_window=true], there are many people experiencing issues relating to the display.

Here's my sources for how I figured this guide out: thanks to these people!
