Unit does not start, shows E2 error, can you help on what that code means and resolution

I have searched and searched and have not been able to find an Owner's Manual for your model Amcor Dehumidifier. I did discover that Haier and Fredrich both have similar models, So similar, I suspect Haier manufactured them. But, neither the Haier nor the Fredich's unit have any information concerning Error Code 2. Plus, the ratings for your Amcor model were not very good. Seems that Amcor is riddled with problems.

In any event, lets try to solve your problem. First, turn the Master ON/OFF Switch to OFF. Unplug the unit from the wall outlet and remove the water collection bucket and the air intake filter. Check the filter closely for significant dust and dirt buildup and clean it if necessary. Make sure the filter is thoroughly dry, before placing it in the unit. Leave the unit unplugged for at least 15 minutes or until the filter is dry. Then replace the filter, insert the bucket - making sure that it fits swaourely from top to bottom into the bucket holder. Plug the unit back in and turn the Master ON/OFF Switch to ON. Hopefully, the 15 minute timeout has allowed the unit's electronics to reset themselves and they reverted back to the original factory settings. If so, set the controls to your liking and the unit should start and run like it should.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.
