The filter on the connection pipeline from the evaporator to the machine head is frozen – has water gotten in?

Evaporator leak: water from the shell side enters the Freon circuit； If the oil has been changed with fluorine-added fluid, the newly added Freon contains water, and the newly added lubricant is of poor quality ； The frozen pipes/filters need to be cleaned, and the entire system should be dehydrated using silicone… It’s also necessary to consider whether there might be issues with the insulation of the compressor motor……
Thank you all; I checked and found a leak in the copper tubes of the evaporator. It’s already blocked; change the oil and refrigerant.
