When & How We Fix Common Dishwasher Problems

A dishwasher should make life easier — not leave you with cloudy glasses, puddles on the floor, or dishes dirtier than when they went in. At Nate’s Appliance Repair, we diagnose problems quickly, explain the cause clearly, and fix the issue the right way the first time.

Below you’ll find the most common dishwasher problems, what causes them, and when you should call a professional.

1. Dishwasher Not Draining (Standing Water in Bottom)

What You’ll Notice

• Water pooled in the bottom after cycle

• Dirty water smell

• Gurgling sounds

Common Causes

• Clogged drain filter

• Blocked garbage disposal connection

• Kinked drain hose

• Failed drain pump

How We Fix It

1. Remove and clean filter assembly

2. Flush drain hose & air gap

3. Check disposal knockout plug (very common on newer installs)

4. Test drain pump motor with meter

5. Replace pump if needed

When to Call

If you’ve cleaned the filter and still have water — the pump or internal blockage is likely the issue.

2. Dishes Still Dirty After Cycle

What You’ll Notice

• Food particles stuck on dishes

2. Test circulation motor pressure

3. Check heater operation (must reach ~120°F+)

When to Call

If your dishwasher sounds normal but cleans poorly, the circulation motor is usually failing — a common repair we handle daily.
