Error code L1 on Enigma SLR-35 air conditioner

Error code on Enigma SLR-35 air conditioner.

The error code is L1, air con will come on for a minute or two and then shut down displaying this error code. I don't have the manual for this air conditioner as it was in a house I just purchased and was just wondering if anyone knows what this error code means before I call in a repairman to investigate.

I have tried cleaning the filters and resetting my circuit breakers for the house. No success obviously. The air that does come out for the minute or two feels cool like the air con is working.

There is what I suspect is a reset button/self test button on the front of the unit which I hold down when powering up and it goes through a bunch of light flashes and beeps but then pops back up with L1 on the lcd display.

Cheers for any help anyone can provide.
