Soleus LX-140 leaking problem
We have a 1-year PE3-09R-03 that just started dripping water on the floor. The red "tank full" light never came on. I opened it up to investigate, and I believe the problems are caused by dust. The plastic float that trips the "tank full" switch appears to have gotten stuck due to the combination of water and dust in the tray. Once I loosened it up and cleaned the guide tube it rides in, it would trip the switch when the tank was full. The reason the tank was filling up was a little less obvious. There is a 2-piece plastic tray that sits underneath the evaporator and above the condenser. The tray is supposed to distribute the water that's dripping from the cold evaporator coils onto the warm condenser coils so it can evaporate and be blown out with the warm exhaust air (note that "evaporator" and "condenser" are referring to the refrigerant - the terms appear backwards when referring to what's happening to the water on the outside). The tray and its lid have a series of tiny holes that were - guess what - plugged by dust. The tray is relatively easy to remove, just two screws and a spring clamp on the overflow hose. The tray lid is heat-staked onto the tray, you should be able to clean it without separating the lid. I cleaned and reinstalled the tray and verified that water would flow properly. I then reassembled the unit and fired it up, and it's been running without a puddle for over a day in humid weather.
The unit has a filter for the recirculating room air, but there is no filter for the outside air loop. Adding a filter would obviously help keep the dust out, but it could also reduce the cooling efficiency of the unit.
DO NOT use one of these on a floor you care about without some sort of emergency catch tray underneath!
