I own a built in Liebherr Refrigerator. I am not sure of the model # but on the "use and care manual" the following numbers a appear: RI 1400 R 1400 KE/es 4250 4807 7082 508-00 The issue I have is that the condensation is so bad that it leaves a pool of water on the bottom that leaks out of the fridge every week regardless of outside temperature. The LED on inside say 42 with a little fan above it. The manual does not give any solution to this issue. Thanks

The evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.


Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help.
Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the inside of the freezer at the bottom of the rear cover.
