Why Is My Dishwasher Making A Grinding Noise?
After completing your dinner cleanup and preparing for a relaxing Netflix session, you notice an unusual sound emanating from your dishwasher, audible even from the comfort of your couch. Dishwashers consist of various components, yet with some basic knowledge, you can effectively diagnose and resolve this bothersome problem. Presented here are seven potential causes for the grinding noise from your dishwasher, along with practical steps to address each issue.
1. Clogged Spray Arms
The spray arms in a dishwasher are essential for effectively washing dishes, but they can occasionally get blocked due to lingering food debris or mineral deposits from hard water.
How to Fix It
Clear out any blockages in the spray arms by using a toothpick or a small wire to remove debris from the openings. To minimize mineral buildup, consider running a vinegar rinse through the dishwasher or using a water filtration system.
2. Blocked Pump
Occasionally, stray food particles or small utensils can get lodged in the pump or chopper blade, leading to an unsettling grinding noise.
How to Fix It
Carefully inspect the dishwasher’s base for any misplaced objects and safely remove anything that shouldn’t be there.
3. Plugged Inlet Valve
A clogged inlet valve can also be a source of grinding noises in your dishwasher. SD Appliance Repair This issue is more common in homes with hard water, where mineral deposits accumulate, restricting water flow and affecting the appliance’s performance.
How to Fix It
To clear a clogged inlet valve, detach the hose, clean the sediment filter if present, and remove any accumulated debris or buildup.
4. Blocked Chopper Blade
Located at the bottom of the dishwasher, the chopper blade helps break down food particles to keep the drain clear. If obstructed by food buildup, utensils, or broken pieces, it may struggle to spin properly, leading to a grinding noise.
How to Fix It

5. Faulty Motor Bearings
Water exposure in the motor bearing can lead to corrosion, potentially causing a grinding noise. However, some dishwashers are designed with sealed bearings that don’t require lubrication, reducing the risk of water damage.
How to Fix It
To avoid motor bearing corrosion, follow the manufacturer’s guidelines for proper lubrication. If the bearings are severely rusted, replacing them may be necessary.
6. Worn-Out Pump Assembly
Your dishwasher features two pumps: a drain pump and a circulation pump. If either becomes damaged or blocked, it could lead to a grinding sound.
How to Fix It
Inspect the pump for any debris and clean it to see if that resolves the issue. If there are signs of damage, replacing the pump will be necessary.
7. Loose Dishes
If dishes are not securely placed, they can shift during the wash cycle and create a loud grinding sound. Luckily, this is a simple issue to correct.
How to Fix It
To resolve this, make sure to load your dishwasher correctly (refer to the manual for guidance) and check for any dishes that may be loose at the bottom.
