The Detergent Dispenser Box is an OEM part for LG washing machines. Housed within the washer door, this compartment delivers precise amounts of detergent at the optimal time. 

Symptoms of a bad dispenser box include:

• Cracks or breaks compromising the dispenser structure
• Detergent leaking or residual buildup outside of the box
• Failure to fully dispense detergent during wash cycles 

Causes of failure can include plastic fatigue from years of opening/closing the washer door. Repeated impacts may also damage internal mechanisms. This OEM LG part can also be used on Kenmore/Sears appliances. 

This inlet hose channels household water to the appliance's fill system. Replacing a worn or leaking hose restores proper water flow and helps protect floors and internal components from water damage.
