[Corrective Action] When there is little or no flow from the bubbler or spout, check the water inlet strainer screen. Sediment from the main supply can get trapped in the screen along with installation materials, such as pipe dope and flux. The screen should be cleaned and checked on a regular basis and replaced if needed. The cartridge valve located in the water control assembly or bubbler can also become clogged with foreign material. The cartridge valve can only be replaced, not repaired. See the exploded view section to locate the cartridge on each cooler model. The water cooler may also develop a freezing condition in which the water will become frozen inside the evaporator coil. This indicates a refrigeration problem or thermostat failure. In this case the water cooler needs to be checked by a qualified technician. [Problem]
