Dishwasher fills with water but does not wash; you hear no spray, only a quiet hum or nothing at all.

Safety First: Disconnect power and water before accessing the bottom of the unit.

Steps:

• Listen carefully: After filling, you should hear a strong spraying sound. A low hum or silence suggests a motor issue.
• Check for obstructions: Remove filters and inspect the sump for debris that could jam the impeller.
• Access motor: Pull the dishwasher out and access the circulation pump from below. Check wiring connections.
• Spin impeller: With power off, try to rotate the impeller by hand. If seized or very stiff, replace the circulation pump and motor assembly.
