Bosch Refrigerator: water pooling

Professional Repair Guide

What is this symptom?

If you notice water pooling inside your Bosch refrigerator or beneath the unit, it's likely due to a clogged defrost drain or other issues preventing proper drainage. This can lead to water accumulation during normal operation or defrost cycles, affecting the efficiency of your appliance and possibly leading to further damage if left unaddressed.
