It looks like you have restriction in refrigerant flow from compressor. Reset the unit and confirm that you realy have too high pressure with measuring high pressure during compressor startup untill error is present again.

If not, and assuming you have OK sensors, then PCB is faulty.

Does error E3 is present in both cooling and heating mode?
