Kenmore Dishwasher Not Cleaning Properly

Kenmore dishwashers present unique cleaning challenges because they're manufactured by multiple companies including Whirlpool, Frigidaire, and LG under the Kenmore brand. This creates complexity in diagnosing cleaning issues, as each manufacturer's design philosophy affects how these units perform. Whirlpool-manufactured Kenmore models (typically 665.xxx series) commonly develop cleaning problems due to their plastic wash pump housing cracking over time, allowing air to enter the system and reducing wash pressure. Meanwhile, Frigidaire-built Kenmore units often suffer from their signature OrbitClean wash arm system clogging, particularly in hard water areas.

The most problematic aspect of Kenmore dishwashers is their tendency to develop mineral buildup in the wash pump motor assembly, especially in models manufactured between 2008-2015. These units used a smaller diameter impeller design that's more susceptible to debris accumulation, leading to reduced water circulation. Additionally, many Kenmore models feature a shared wash/drain pump system that can develop internal leakage, causing poor cleaning performance that's often misdiagnosed as a simple clogged filter issue.
