Diagnosis
A flashing white light with three beeps is the filter replacement alert. The internal timer has expired.
How to Fix It
Reset the filter timer. In the Molekule app, go to Device Settings > Filter Reset. Confirm the reset. The light should return to solid white. If you recently installed a new filter, this is the only required step.
If That Didn't Work
The alert may persist if the filter door is not fully closed. Check that the front cover is securely latched on both sides. Open and firmly close it.
Heads Up
This alert is based on runtime, not actual filter condition. You can reset it with an old filter, but performance will degrade. The official filter lifespan is 6 months.
