Check All the Buttons: The E1 error code sometimes means that one of the control buttons is stuck, particularly on Haier models. Press all the buttons. If you find one that is sticking, free it, and the error code should disappear.

Unfortunately. Haier does not have an online manual for your model AC. However, if you contact their Customer Support Dept 1-877-337-363, they can tell you what the code means and supply you with an Owner's Manual for future reference.

Hope this helped you.
