What to Do If Your Dishwasher Isn’t Cleaning Dishes Properly
Why Your Dishwasher Isn’t Cleaning Dishes Properly—and What to Do About It
You just ran the dishwasher, but your dishes still come out cloudy, greasy, or worse—dirty. What gives?
When your dishwasher isn’t cleaning dishes properly, it’s not just frustrating—it’s a signal that something’s not right. Whether you live in Aurora, Wheaton, or anywhere in the Chicago suburbs, this guide will help you figure out why—and what to do about it.
Premium Appliance Repair assists homeowners in repairing dishwashers that appear to be in excellent working order but fail in critical areas. Let’s look at what’s going wrong—and how to get clean results again.
Top 5 Causes: Why Your Dishwasher Isn’t Cleaning Dishes Properly
Here are the most common causes we see during dishwasher repair near me service calls:
1. Clogged Spray Arms
If the spray arms are blocked by food particles or mineral deposits, water won’t reach all the dishes. You can try removing and cleaning them—but if spray pressure is weak, it may need professional servicing.
2. Dirty or Blocked Filter
A full filter restricts water flow and causes food bits to recirculate. If you haven’t cleaned your filter in a while, this could be your culprit.
3. Incorrect Loading
Stacking plates too close together? Large pots blocking the arms? This disrupts spray patterns. It’s a simple fix, but it’s easily overlooked.
4. Low Water Temperature
Water needs to reach at least 120°F to dissolve grease and detergent properly. If your water heater isn’t pulling its weight, cleaning performance will suffer.
5. Hard Water Buildup
Minerals in hard water leave a film on dishes and can block internal components. You may notice white spots or residue.

DIY Fixes You Can Try Before Calling a Pro
Before you search appliance repair Aurora, IL, try these quick steps:
- ✅ Run a Vinegar Cleaning Cycle
Pour a cup of white vinegar into a dishwasher-safe bowl on the top rack and run a hot cycle. It helps break down grease and mineral deposits. - ✅ Clean the Filter (Bottom Rack)
Unscrew the circular filter (if removable), rinse under hot water, and scrub with a soft brush to remove food debris and buildup. - ✅ Soak and Clear Spray Arms
Remove spray arms and soak them in warm, soapy water. Use a toothpick to clean out clogged jets. - ✅ Try a Different Detergent + Use Rinse Aid
Cheap or expired detergent might not dissolve properly. A rinse aid helps eliminate water spots and improves drying. - ✅ Check Water Temperature
Run hot water in the sink before starting the dishwasher. If it takes a long time to get hot, your water heater may need adjusting.
If the problem keeps returning, it’s probably time to call in a technician.
When to Book a Dishwasher Repair Appointment

Book dishwasher repair in the Chicago suburbs if you notice:

What Our Technicians Look For
When we arrive for a dishwasher repair near me service call, we go beyond surface-level issues. Here’s what we inspect:
- Spray Arm Pressure and Rotation
We check that water pressure is strong and arms are spinning freely—blockages or failed pumps can reduce this. - Water Inlet Valve & Circulation Pump
These parts control how water enters and moves through the dishwasher. A faulty valve can mean no spray; a weak pump results in underpowered cleaning. - Filter Blockage or Drain Hose Clogs
We inspect for food buildup, tough water residue, or improper drain setup that could send dirty water back into the tub. - Control Panel & Sensors
Modern dishwashers rely on sensors to detect water levels and soil levels. A malfunction here can affect the entire cycle. - Heating Element
Final rinse cycles rely on high heat. If dishes come out wet and cold, the heating element or thermostat may be to blame.
Our Aurora-based team stocks common parts, so we can often resolve the problem with same-day appliance repair.
