After switching on the ac unit water start
I assume inside the air handler closet, underneath the unit, or wherever unit is located. Sounds like condensate line is stopped up.You need to blow out with compressed air. You must make sure that you block air from exiting from open end of line. I use a plastic shopping sack. May have to remove cover to evaporator and insert hose in condensate drain connection in drain pan. Stuff the bag in around hose and opening to seal and blast air into line. Be sure that if there is a "T" fitting with riser and cap on the end, that it is secure, otherwise you may get a shower. You also may use the riser with the cap remove to blow out. insert hose past opening leading back to evaporator drain push bag down past opening leading back to evap drain, then seal around inserted hose and blast. The riser with the cap is where you would pour some bleach every couple of months to keep line clear.
Red blinking and ac not working
If the power "flickers" and unit fails but will restart once the breaker is reset, this sounds absolutley normal. It is a safety device that keeps the unit from burning up things due to improper power being supplied. As long as resetting puts it back into service with no issues, don't worry about it.
