If your GE dishwasher is not cleaning dishes, smells bad, or leaves white spots on dishes, it may be time for a good cleaning! Making sure your dishwasher is as clean as the dishes it washes might not always be at the top of your mind. You’re likely keeping the outside neat, but what about the inside where the real work happens? What can you do to prevent dishwasher smells? Or how can you fix a dishwasher that’s not cleaning well? Simply giving your dishwasher a thorough inside cleaning can help with these problems and is easier than you might think. This guide walks you through a detailed, step-by-step process to clean your GE dishwasher, addressing common issues like odors, poor cleaning, and hard water stains.
Why Cleaning Your GE Dishwasher Matters
Before diving into the cleaning process, let’s understand why it’s essential. Dishwashers handle food scraps, grease, and detergent residue daily, which can accumulate in hidden areas like filters, spray arms, and door seals. Over time, this buildup can lead to:
- Unpleasant Odors: Trapped food particles and mold growth in filters or drains can cause bad smells.
- Poor Cleaning Performance: Clogged spray arms or filters reduce water flow, leaving dishes gritty or streaked.
- Hard Water Deposits: Mineral buildup from hard water can leave white films on dishes and interior surfaces.
- Reduced Lifespan: Neglecting maintenance can strain the dishwasher’s components, leading to costly repairs.
According to Steve Moore, founder of Moore Appliance Service in Southern Pines, NC, “Regular cleaning of your GE dishwasher’s filters and interior prevents clogs and odors, ensuring optimal performance and hygiene.” By dedicating a little time to maintenance, you can avoid these issues and keep your dishwasher in top shape.
How to Clean Out GE Dishwasher
Tools and Materials You’ll Need
To clean your GE dishwasher effectively, gather these items:
- White vinegar (2 cups)
- Baking soda (1 cup) or a commercial dishwasher cleaner like Affresh or Finish Dishwasher Cleaner
- Mild dish soap
- Soft sponge or cloth
- Soft-bristled brush (e.g., an old toothbrush)
- Paper clip or tweezers (for unclogging spray arm jets)
- Protective gloves (optional, to avoid skin irritation)
- Candy or meat thermometer (to check water temperature)
- Bucket (for checking drain hose clogs)
Safety Tip: Always unplug the dishwasher or turn off the power at the breaker before cleaning to avoid electrical hazards. If your kitchen has a light switch controlling the dishwasher, use it to cut power.
Step-by-Step Guide to Cleaning Your GE Dishwasher
Follow these five detailed steps to restore your GE dishwasher to peak performance. This process covers the interior, filters, spray arms, drain, and exterior, addressing all common problem areas.
Step 1: Empty and Inspect the Dishwasher
Start by removing all dishes, utensils, and racks from the dishwasher. This gives you full access to the interior. Check the bottom of the tub for visible food scraps or debris. Use a damp cloth or sponge with mild dish soap to wipe away any loose particles. Pay special attention to the corners and crevices where gunk tends to collect.
Pro Tip: Avoid using abrasive pads or harsh cleaners, as they can scratch the stainless steel interior of many GE models. If you notice standing water at the bottom, it could indicate a clogged drain or filter, which we’ll address in later steps.
Step 2: Clean the Filters
Most newer GE dishwashers have Fine and Ultra Fine Filters that require regular maintenance (unlike older models with self-cleaning filtration). These filters trap food particles to prevent clogs in the drain and pump, but they can become breeding grounds for mold and odors if neglected.
How to Clean the Filters:
- Remove the Bottom Rack: Slide out the lower rack to access the filters at the base of the tub.
- Remove the Ultra Fine Filter: Locate the cylindrical Ultra Fine Filter (often marked with an arrow). Twist it counterclockwise and lift it out.
- Remove the Fine Filter: Find the two retaining posts at the back of the tub’s base. Twist them counterclockwise to release the Fine Filter (a flat mesh plate) and lift it out.
- Clean the Filters: Rinse both filters under warm, soapy water. Use a soft sponge or brush to gently scrub away food particles, grease, or hard water deposits. Avoid scouring pads, as they can damage the filter mesh.
- Clean the Filter Housing: Wipe the area where the filters sit with a soapy cloth to remove any trapped debris.
- Reinstall the Filters: Place the Fine Filter back under the retaining posts and twist clockwise to secure. Reinstall the Ultra Fine Filter by twisting it clockwise until it locks.
Frequency: Clean the filters every other month or more often if you notice gritty dishes or reduced wash performance.
Step 3: Clean the Spray Arms
The spray arms are critical for distributing water to clean your dishes. If their jets are clogged with food or mineral deposits, water flow is restricted, leading to dirty dishes, especially on the upper rack.
How to Clean the Spray Arms:
- Remove the Spray Arms: For most GE models, the lower spray arm can be pulled straight up or unscrewed. The upper or middle spray arm may be attached to the underside of the top rack or a water supply nozzle. Check your manual for model-specific instructions.
- Inspect for Clogs: Look for food particles or hard water buildup in the spray arm holes. Use a straightened paper clip or tweezers to gently clear any blockages.
- Rinse and Scrub: Rinse the spray arms under warm running water. Use a soft brush to remove stubborn debris.
- Reinstall: Secure the spray arms back in place, ensuring they spin freely.
Troubleshooting Tip: If the upper rack isn’t cleaning well, check the water supply nozzle connecting to the upper spray arm for obstructions.
Step 4: Run a Cleaning Cycle with Vinegar and Baking Soda
To tackle grease, limescale, and odors, run two cleaning cycles using household staples: white vinegar and baking soda. These natural cleaners are safe, effective, and won’t damage your dishwasher’s interior.
Vinegar Cycle:
- Place a bowl or glass containing 2 cups of white vinegar on the bottom rack of the empty dishwasher.
- Run a hot water cycle (ensure the water temperature is at least 120°F for optimal cleaning; use a thermometer to check).
- The vinegar will break down grease, limescale, and mineral deposits, leaving the interior fresh.
Baking Soda Cycle:
- After the vinegar cycle, sprinkle 1 cup of baking soda across the bottom of the tub.
- Run a short, hot water cycle. The baking soda will neutralize odors and scrub away remaining residue.
Alternative: If you prefer a commercial cleaner, use a product like Affresh or Finish Dishwasher Cleaner. Place one tablet at the bottom of the tub and run a normal cycle with hot water. These cleaners are formulated to target grease, limescale, and odors effectively.
Note: Don’t mix vinegar and baking soda in the same cycle, as they neutralize each other’s cleaning properties.
Step 5: Clean the Exterior and Door Seals
The exterior and door seals are often overlooked but can harbor grime and mold, contributing to odors and potential leaks.
Cleaning the Exterior:
- For stainless steel models, use a non-abrasive cleaner like Cerama Bryte Stainless Steel Polish or Bar Keepers Friend Soft Cleanser to remove fingerprints and smudges.
- For matte or painted finishes, wipe with a soft, damp cloth and mild soap, then dry thoroughly to prevent streaks.
Cleaning the Door Seals:
- Use a soft cloth or toothbrush dipped in white vinegar to scrub the rubber seals around the door and under the bottom rack.
- Pay close attention to crevices where food and mildew can accumulate.
- Wipe with a clean, damp cloth to remove vinegar residue.
Maintenance Tip: Inspect the door seal for wear or damage. A compromised seal can cause leaks, so replace it if necessary.
Addressing Common GE Dishwasher Issues
Here are solutions to specific problems you might encounter:
- Smelly Dishwasher: Persistent odors often stem from trapped food in the filter, drain, or door seals. Run the garbage disposal for 10-20 seconds before starting a wash cycle to clear food particles, and ensure the drain hose is free of kinks or clogs.
- Dishes Not Cleaning Well: Check for overcrowding, which prevents water from reaching all surfaces. Ensure the water temperature is at least 120°F, and use a high-quality, phosphate-free detergent with enzymes.
- White Film or Hard Water Spots: Hard water deposits can be tackled with regular vinegar cycles or a rinse aid like Jet-Dry to prevent spots.
- Standing Water: A clogged drain hose or air gap (located near the sink) could be the culprit. Straighten any kinks in the hose under the sink, and use a long cleaning brush to clear blockages.
Expert Insight: Steve Moore advises, “If your GE dishwasher still isn’t cleaning well after a thorough cleaning, check the drain hose installation. A common mistake is not positioning the hose high enough under the countertop, which can cause sink water to flow back into the dishwasher.”
How Do I Get Rid of Standing Water in My Dishwasher?
If you notice standing water in your dishwasher, there are a few possible causes. The most common cause is a clogged or kinked dishwasher drain hose.
To check your dishwasher drain hose:
- First, locate the dishwasher drain hose. It is typically located under the sink.
- Next, check the drain hose for any kinks or blockages.
- If you find any kinks, straighten out the drain hose so that it can flow freely.
- If you find any blockages in the drain hose, use a long cleaning brush to remove the obstruction gently.
- Lastly, check the dishwasher’s air gap (located on the back of the sink) to ensure it is clear of any debris. If your dishwasher’s air gap is clogged, you will need to clear it with a small brush or tool.
Why Does My Dishwasher Leave Water Marks?
If your dishwasher leaves water marks on dishes, it is likely due to hard water. Hard water contains high levels of minerals, such as calcium and magnesium, which can leave spots on dishes after they have been washed. To prevent hard water spots, remove excess food from your dishes before loading them into the dishwasher, and use a rinse agent with each load.
Maintenance Tips to Keep Your GE Dishwasher Running Smoothly
- Run Hot Water Before Starting: Run your kitchen faucet on hot until the water is at least 120°F to ensure the dishwasher starts with hot water.
- Use the Right Detergent: Avoid regular dish soap, as it creates excessive suds that can clog the system. Stick to automatic dishwasher detergents or gel.
- Load Properly: Space dishes evenly, avoid nesting utensils, and ensure nothing blocks the spray arms or detergent dispenser.
- Schedule Regular Cleaning: Clean the filters and run a vinegar or commercial cleaner cycle every 1-2 months, depending on usage.
- Check for Professional Service: If problems persist, schedule a professional maintenance visit. Sears Home Services or Moore Appliance Service can diagnose and fix issues like faulty pumps or sensors.
When to Call a Professional
If you’ve followed these steps and your GE dishwasher still has issues—such as persistent odors, poor cleaning, or error codes—it may need professional attention. Problems like a faulty circulation pump, water inlet valve, or turbidity sensor require specialized tools and expertise.
Conclusion
Cleaning your GE dishwasher doesn’t have to be a daunting task. By following these five steps—emptying and inspecting, cleaning filters and spray arms, running vinegar and baking soda cycles, and maintaining the exterior—you can eliminate odors, improve cleaning performance, and extend your appliance’s life. Regular maintenance, paired with proper loading and detergent use, ensures your dishwasher delivers spotless dishes every time.
