Take it back to seller. We;re on our third unit doing the same thing.

was the filter dirty that will do it let it defrost and put it back on

same thing happend to me. I wasnt sure if it was the settings or me. I unplugged it for awhile, read thru the instructions turned it back on setting it according to the instructions and it began to work again. Not sure if it had to do with the unit being off for awhile or I entered the correct settings. Im just happy it began to run again

I am searching for a resolution to the E3 code (same init) and happened upon this request. The manual can be downloaded from DeLonghi.com but that advises you to call the service center.

What I found was that the evaporator coil has steel endplates that flake rust off into the resevoir. This clogs and destroys the pump.

is there a solution for the E3 code?

Hi.
It is simple and easy to fix. E1 code for sensor behind right side grill. Take right side grill out, unplug sensor from wire socker and plug back. It is solve problem sometimes. Unit MUST be unplugged from outlet.
If no help, you need new sensor .

Thank you.
