Why Your Dishwasher Has Standing Water

The myth: Standing water in a dishwasher means the dishwasher is broken and needs to be replaced.
The reality: Standing water almost always means one of four components has failed or become blocked. All four are repairable.

The Four Drain Failure Sources We Find in Knob Noster, MO

1

Clogged Drain Filter

Most common cause. Modern dishwashers require manual filter cleaning. Heavily clogged filters restrict drainage.

2

Failed Drain Pump

The motor that pushes water out. No drainage sound or humming with no movement.

3

Blocked Drain Hose

Kinked, crushed, or grease buildup prevents water from exiting.

4

Check Valve Failure

Allows water to flow back into the tub after draining.

Why Your Dishwasher Smells Bad

The smell has a source. The most common source is the filter... The second source is the door gasket... The third source is the spray arms... The fourth source is the sump.

Once you've addressed the filter, the gasket, and any drain issues, run an empty hot cycle with white vinegar followed by baking soda.
