Maytag Dishwasher: not filling with water

Professional Repair Guide

What is this symptom?

If your Maytag dishwasher is running but not filling with water, it can be frustrating. This issue often stems from a closed water supply valve, a malfunctioning door latch, or a failing control board. Understanding these causes can help you troubleshoot effectively and restore your dishwasher's functionality.
