Dishwasher fills with water but does not wash; spray arms do not move and you hear no strong motor noise.

Safety first: Turn off power and water.

• Listen during wash: After filling, you should hear a strong, steady motor sound. A faint hum or silence indicates a motor issue.
• Check for obstructions: Remove lower rack, spray arm, and filters. Inspect the sump for debris that could jam the impeller.
• Access motor: From underneath, locate the circulation pump. Try to rotate the impeller shaft by hand; it should move freely.
• Test motor: Disconnect the motor and measure resistance across its terminals. An open circuit or very high resistance indicates a failed motor.

Repair action: Clear any debris. If the motor is seized or electrically open, replace the circulation pump and motor assembly. Confirm no leaks after reassembly.
