True commercial cooler model GDM-49-LD. Been fine for several years. Water now accumulating in cooler floor. Origin seems to be back wall dead center. Any suggestions ?
Drain tube runs from dead center of the coil into the back wall and down under the unit where it drains into a pan and is evaporated. Sounds like just a blocked drain tube. The easiest way to clear this is to take the bottom front grill off and look for the drain tube which is typically just strapped to the top of the opening suspended over the pan. Use a wet vac to pull out the sludge or some kind of pressure to blow it back up into the cabinet. Problem with blowing back is that dirt and water are going to blow into the cabinet and/or coil. taking the hose off of the interior coil is difficult and you can break the plastic connector so I don't recommend that to anyone.
