Amana Dishwasher: making noise

Professional Repair Guide

What is this symptom?

Is your Amana dishwasher making unusual noises like grinding, humming, or rattling? Such sounds during the fill, wash, or drain cycles can indicate issues with the circulation pump or water inlet valve. Addressing these noises early can prevent further damage and costly repairs.

Urgency: Medium

Important Tips for Amana Models

  • Amana’s official docs confirm normal operational sounds (water fill, swishing, drain hum) and highlight installation and loading as factors in perceived noise levels.
  • Some Amana models use a combined circulation and drain pump; wear in these assemblies often manifests as noise.

Possible Causes

Worn or damaged circulation pump (motor bearings or impeller)

How to Identify: Loud humming, grinding or whining during wash cycle; noise correlates with water circulation stage.

Part: Circulation pump / motor

Water inlet valve vibration

How to Identify: High-pitched squealing during fill cycle only.

Part: Water inlet valve
