Not Draining in Reseda

Reseda's housing boom in the 1950s and 1960s created a neighborhood filled with practical ranch-style homes and duplexes, most equipped with original or replacement mid-range dishwashers from brands like Whirlpool, GE, and Kenmore. These workhorses have served families well for decades, but the combination of aging drain lines and garbage disposals means dishwasher drainage issues are increasingly common. We see this problem frequently in the older tract homes along Reseda Boulevard and the surrounding residential streets, where original plumbing systems are now showing their age.

The San Fernando Valley's hard water compounds drainage problems in Reseda dishwashers. Mineral deposits build up in drain hoses and air gaps over time, creating blockages that prevent proper water evacuation. During our service calls throughout the 91335 area, we regularly find dishwashers with standing water caused by these mineral accumulations, especially in homes that haven't had regular maintenance on their water softening systems.

Common Causes

Clogged drain hose or air gap, failed drain pump, food debris in sump, or garbage disposal knockout plug.

Specific to Reseda:

Reseda's extremely hard water, typical throughout the San Fernando Valley, accelerates mineral buildup in dishwasher drain components. The valley's hot, dry summers also stress older appliances, causing seals and pump components to deteriorate faster. Many Reseda homes still have their original garbage disposals from the 1960s and 70s, which can develop clogs that back up into connected dishwashers. Additionally, the area's mature landscaping means older homes often have tree roots infiltrating sewer lines, creating drainage issues that affect kitchen appliances.

DIY Troubleshooting Steps

Clean drain filter. 2. Run garbage disposal. 3. Check air gap. 4. Inspect drain hose for kinks.
