KitchenAid Dishwasher: leaking

Professional Repair Guide

What is this symptom?

Experiencing a leak from your KitchenAid dishwasher? Water pooling at the bottom of the door or underneath during or after a wash cycle can indicate issues such as a worn door gasket, improper loading, or loose hose connections. Addressing these problems promptly can prevent water damage in your kitchen.

Urgency: Medium

Important Tips for KitchenAid Models
