The laser tube should avoid generating incrustation which would cause water stemming. If there is incrustation,

b) Current is available (check if the mirrors and lens);
c) Check if the water circulation system works well or not;
d) Without water: check the water chiller is electrified or damaged;
e) With water: check the water inlet and water outlet if they are connected inversely or the water pipe is broken;
