Common Dishwasher Faults & How to Fix Them | Domestic Appliance Installation

Is your dishwasher acting up? A faulty dishwasher can be frustrating, especially when dishes come out dirty or the appliance won’t start at all. At Domestic Appliance Installation, I’ve compiled a comprehensive guide to the most common dishwasher problems and their potential solutions — so you can get your kitchen back to normal fast.

Top 10 Most Common Dishwasher Faults

1. Dishwasher Won’t Start

Your dishwasher might not start due to:

  • Door not properly latched

  • Faulty start button or control panel

  • Power supply issues

Quick Fix: Check the power cord and door latch. If those are working, the control board may need professional repair.

2. Dishes Come Out Dirty

One of the most common complaints, dirty dishes could be caused by:

  • Clogged spray arms

  • Water not heating

  • Overloading the dishwasher

🧽 Solution: Clean the spray arms and filters, avoid overpacking, and run a hot wash cycle.

3. Water Not Draining

If there’s standing water in your dishwasher:

  • The drain hose may be blocked

  • The drain pump could be faulty

  • The filter might be clogged

🛠️ Pro Tip: Clean the filter and inspect the drain hose. Still having trouble? You may need a technician.

4. Leaking Dishwasher

Leaks are usually caused by:

  • A worn-out door gasket

  • Loose or cracked hoses

  • Overfilling or improper detergent use

💧 Fix: Check the seal around the door and inspect for loose connections.

5. Dishwasher Making Unusual Noises

Unusual sounds may be due to:

  • Items interfering with the spray arms

  • Worn pump or motor

  • Loose internal parts

🔊 Tip: Remove loose utensils or large items and try running a cycle empty. Persistent noise should be inspected by a pro.

6. Bad Smells Coming From Dishwasher

Foul odors come from:

  • Food debris stuck in filters or drain

  • Mold and mildew buildup

  • Using cold water cycles too often

🌿 Maintenance Tip: Clean the filter regularly and run a vinegar or baking soda cycle monthly to freshen the interior.

7. Dishwasher Won’t Fill With Water

This issue might stem from:

  • A faulty water inlet valve

  • A stuck float switch

  • Low water pressure

🚰 What to Check: Ensure the water supply is on and no visible pipes are kinked.

8. Dishwasher Doesn’t Dry Dishes

If your dishes come out wet:

  • Heating element may be broken

  • Rinse aid dispenser might be empty

  • Using an eco cycle without heat drying

🌬️ Solution: Refill rinse aid and check if the water is heating.

9. White Film or Cloudy Glassware

This is often caused by:

  • Hard water deposits

  • Not enough rinse aid

  • Too much detergent

🧼 Fix: Use a dishwasher cleaner and add rinse aid. A water softener may help long-term.
