What to do if my Sinclair AMC-11P shows error E4?

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