This video explains an approach that we use to at BoatAC.net to repair marine air conditioners that are having problems with water pressure, overheating or E4 codes. We attach high pressure air to a column of water and blow the water through the system at high pressure to clean the debris.
In this video, you'll see how we connect a Dometic Cruisair marine ac to clean water and high pressure air to clean out the inside of the air conditioner and all the hoses.
