Ge Dishwasher: not cleaning

Professional Repair Guide

What is this symptom?

Is your GE dishwasher not cleaning effectively? If dishes come out with food residue, spots, or are only partially cleaned, you might be facing issues like clogged spray arms, dirty filters, or improper loading. Weak water spray or inadequate rinsing can also contribute to this frustrating problem. Understanding the root causes can help you restore your dishwasher's cleaning power.
