None Dishwasher: error code 15

Professional Repair Guide

What is this symptom?

If your dishwasher displays error code 15 (E15/F15), it indicates a triggered leak detection system, often due to water in the base pan. This error can cause the dishwasher to stop mid-cycle or prevent it from starting. Common causes include water leakage, a damaged door seal, loose hoses, excessive suds from detergent, or a clogged drain. Understanding the issue can help you take the right steps toward a solution.

Urgency: Medium

Important Tips for None Models

Part: Door seal (gasket)

Loose or damaged internal hoses

How to Identify: Water drips or moisture under unit; hoses appear loose, cracked, or incorrectly seated.
