RevAir has 2 different illuminated light sequences within the Handle to help diagnose the issue

Light  Sequence Guide

• Fast flashing sequence = 1 sec in between each flash.  This is an indicator the device is not getting proper airflow which can be caused by the below:
  • Clogged/Dirty filter - water should be able to freely run through the mesh portion of the filter.  If water is standing still or slowly draining your filter needs a good scrub.  Click HERE for directions on how to clean
  • Kink in hose - check the entire length of the hose to see if there are any kinks or damaged areas
  • Back of the unit is too close to a wall not allowing exhaust air to freely move

• Slow Flashing Sequence = 3 seconds in between each flash.  This is an indicator the Filter or Filter Panel is not connected.  Check the following:
  • Power Off Base of the device and unlock the Filter panel 
  • Remove the Filter basket from Base
  • 
  • Then reinsert the Filter Panel, making sure that the plastic lip on the panel is set into the groove on the inside of the Base unit. Listen for a soft click and relock.
