Common Causes of Dishwasher Grinding Noises

When it comes to dishwasher grinding noises, a few common culprits could be behind the racket in your kitchen. Here are some potential reasons why your dishwasher is making that grinding sound:

• Foreign Objects: Items like broken glass, popcorn kernels, or small utensils can get stuck in the dishwasher’s pump or spray arm, causing it to grind.
• Worn-out Parts: Over time, parts like the bearings, seals, or wash arm assemblies can wear out and make grinding noises as they move.
• Drain Impeller: A malfunctioning drain impeller can also lead to grinding sounds, especially if it’s clogged with debris.
• Motor Issues: Problems with the dishwasher’s motor, such as a damaged motor bearing or a faulty motor pump, can result in grinding noises during the wash cycle.
• Faulty Pump: A damaged circulation or drain pump can cause the dishwasher to make unsettling grinding sounds as it struggles to operate smoothly.
