Hello, I will do my best to refer you, however no electrician is trained or experienced with those units... In china, at $1 per hour labor rates those are repairable... in the USA at $100 an hour labor rates, it can cost as much to repair them as to buy new unit.
That is the reason many appliance repair shops in the USA will no work on them, the other reason is that getting parts for many of these chinese brands can be difficult or impossible.
Having said that, you might be able to remove the condensate bucket from the unit and clean off the water level sensor inside at the top of the bucket, or replace the sensor.
Here is a short list of shops in your area that might possibly accept the unit for repairs (but at prices that I might consider to be too high considering the cost of a new unit.)

NONE of those are well rated! Except AARS... and if you click on their web site link you get Casino advertisements.. it is a bogus company with a 5 star rating,
Let me know if you would like me to spend a few hours coaching you through repairs or not, we can go from there.
