Got to my wash last night after we had some rain and my wash select ii was acting crazy. Opened it up and the back of the door was wet as were the keypad and speaker. The seal is fine on my door. The pattern of the water made it look like it was sweating instead of rain coming in. The fan in the back bottom of the unit is working also. It was around 100 degrees yesterday and it dropped to 70 or so all of a sudden when the rain came. Has anyone encountered this? Is it rain or sweating?

Perhaps it's from rain water coming in through a worn/old credit card reader gasket in need of replacement?

I have a new credit card reader and gasket. I left if off over night to dry out and it worked fine the next day. Ive looked it over and all the gaskets look good. Don't know what to do now. Thought about doubling the door gaskets up?

Being in Florida, I have some experience with what you described. If the inside air was around 100 with the same humidity, and it dropped to 70, you would definitely get condensation inside the door. This is the same way water gets into our air compressors and pumps. I had a rather unique experience with this many years ago flying skydivers in a small Cessna. We had a weather inversion that meant the air cooled as I climbed to altitude. Usually the cooler air stays close to the ground because it's more dense. Sometimes a cold front overtakes a warm area and the cold air is on top. So after the jumpers left I closed the door and headed down. Well when the now cool air and panel inside the aircraft dove into the warm moist air below, all of a sudden I had instant condensation on all interior surfaces. Could not see out the windows, and all of the instruments were fogged over. Made for a rather interesting time. Sort of like flying with your eyes closed. Fortunately I just opened the jump door to look out and see the horizon. But I digress.
