The Drain Hose Assembly is an OEM part for LG dishwashers. This crucial component ensures the effective expulsion of used water from the dishwasher to the home's drainage system. 

Causes of a bad drain hose assembly often include clogging due to food particles and debris, which can obstruct water flow. Additionally, physical damage like cracks or splits from wear or improper installation can compromise the hose's integrity, leading to leaks or backups.

Symptoms of a faulty drain hose assembly include:

• Water leaking from beneath the dishwasher.
• Failure to fully drain water at the end of a cycle, leaving residue and odors.
• Visible signs of wear or damage to the hose.

The Check Valve is an OEM part for LG dishwashers. It prevents the backflow of water into the dishwasher, ensuring that water only flows in the intended direction. This helps maintain the efficiency of the washing cycle and prevents contamination of clean dishes.

The check valve can fail due to reasons such as wear and tear, blockage from debris or hard water deposits, or damage from high water pressure. Over time, the internal components can degrade, leading to improper sealing.

Symptoms of a bad check valve include:

• Water backing up into the dishwasher
• Poor cleaning performance due to improper water flow
• The dishwasher not draining properly
• Unusual noises during the wash or drain cycles

This OEM LG part is also compatible with certain models of Kenmore dishwashers.
