5 DIY Tips to Silence a Noisy GE Dishwasher

Share this expert tip!

The harmony of a smoothly functioning kitchen is often disrupted when an appliance starts acting up. Especially when that appliance is your GE dishwasher. If you’re wondering, “Why is my GE dishwasher making a loud noise?”, you’re in the right place. Here, we break down potential causes of a noisy GE dishwasher and how you can bring back the quiet.

Unraveling the Symphony of Sounds from a Noisy GE Dishwasher

It’s essential to understand that dishwashers have their natural operational sounds. However, when these noises become irregular or too loud, they can indicate an underlying issue.

Dishes Are Too Crowded

One of the most common reasons for a GE dishwasher making noise during the wash cycle is overcrowded dishes clinking against each other.

When dishes are placed too close together, the force of water can cause them to knock into one another. Plates, glassware, or even silverware banging together can create quite a racket.


  • Inspect Loading Patterns: Before starting the dishwasher, ensure that no dishes overlap or are packed too tightly. Glassware and cups should be spaced apart in the top rack, while plates, bowls, and bigger items should be on the bottom.
  • Check for Dislodged Items: Sometimes, smaller items like teaspoons can slip through and bang against the dishwasher’s walls.


  • Load Thoughtfully: Use separators where possible, and if you’re unsure about how to load specific items, refer to the user manual.
  • Opt for Quality Detergent: This ensures efficient cleaning, minimizing the need to overload the dishwasher.

Spray Arm Is Blocked or Clogged

A clogged or blocked spray arm is another culprit behind a noisy GE dishwasher.

The spray arm circulates water to clean dishes. If it’s obstructed, it can make thudding or whirring sounds. Blockages often occur from accumulated food particles or a fallen utensil.


  • Stop and Inspect: If you notice a sudden noise, pause the dishwasher and check the spray arm for visible obstructions.
  • Clean the Spray Arm: Remove it if possible and run water through it to clear out any debris. Check the small holes on the arm – these can get clogged over time.


  • Regular Cleaning: Every few weeks, give the spray arm a once-over to prevent buildup.
  • Scrape Dishes: Before loading, scrape large food particles off the dishes to minimize the chances of clogging.

Water Supply Noises

Water supply issues, like a kinked inlet hose or a defective water inlet valve, can result in various noises, ranging from humming to banging.

The water inlet system is responsible for the water flow into the dishwasher. Any issue here can not only cause noise but also affect the washing efficiency.


  • Inspect the Inlet Hose: Turn off the dishwasher and examine the hose for any visible kinks or bends. Straighten if needed.
  • Listen for Valve Noises: A defective valve may make a continuous humming sound.


  • Replace Old Hoses: Over time, hoses can become brittle or damaged. Periodically replacing them can prevent kinks and cracks.
  • Professional Inspection: If you suspect a valve issue, it might be best to have a professional evaluate it. A malfunctioning valve could impact water efficiency and increase noise.

Pinched or Obstructed Drain Hose

The draining phase can become noisy if there’s an issue with the drain hose.

The drain hose leads wastewater out of the dishwasher. Any obstruction or pinch can cause gurgling or bubbling sounds.


  • Check Hose Position: Ensure it’s not bent or twisted.
  • Look for Obstructions: Check both ends of the hose for any debris or foreign objects.


  • Correct Installation: Ensure that during installation, the hose is positioned with a high loop to prevent backflow.
  • Regularly Inspect: A quick monthly inspection can help detect potential issues before they become problematic.

Drain Pump Is Clogged

A clogged drain pump can be the root cause of a GE dishwasher making loud noises, especially during the draining phase. If left unchecked, a clogged drain pump can even lead to foul odors in your dishwasher.

The drain pump effectively removes wastewater. However, large food particles or broken glass can clog it, causing loud grinding noises.


  • Inspect the Pump: Turn off and unplug the dishwasher before doing so. Look for any visible obstructions and remove them.
  • Run a Test Cycle: After inspecting and cleaning, run a short cycle to check if the noise persists.


  • Scrape Dishes Well: The more thoroughly you scrape your dishes before loading, the less likely debris will end up in the drain pump.
  • Regular Maintenance: Every couple of months, inspect the pump to ensure it’s clear of any debris.
