Maytag Dishwasher: clogged cleaning arms

Professional Repair Guide

What is this symptom?

Is your Maytag dishwasher leaving dishes dirty due to clogged cleaning arms? This common issue leads to ineffective spraying as food debris, mineral buildup, or grease blocks the spray arm holes, resulting in spots and food residue. Regular maintenance can help restore optimal cleaning performance.

Urgency: Medium

Important Tips for Maytag Models

  • Maytag’s official guidance recommends regular interior cleaning and dishwasher cleaning products like affresh® to reduce residue on internal components such as spray arms.
