Gree E2 fault code
Gree air conditioning
What the Gree E2 fault code means, from the manufacturer's own service literature, and the UK models it applies to.
What it means
The indoor coil has fallen cold enough to risk icing and the unit has protected itself. On a refrigeration circuit this is an airflow or charge question.

Now the harder half: proving what caused it
E2 names a symptom, not a root cause. In the app, the same code opens a guided investigation: what to measure first, the expected values for your exact model, and an honest verdict — including “nothing in this machine is broken” when that's what the readings say.
