What to do if my EQUATION PC26-AMFII Air Conditioner shows error E4?

If your EQUATION Air Conditioner displays error code E4, it means the water tank is full or the plug is incorrectly wired. To fix this, remove the rubber stopper at the bottom of the unit to drain the water. Also, verify that the plug has been wired correctly.
