Description

This wiring harness connects the dishwasher's water inlet valves to the control system so valves receive power and signals when a cycle calls for water. Replacing a damaged harness restores reliable valve operation and correct water fill control. What it does:

• Provides power and signal paths between the control board and water inlet valves
• Enables valves to open and close during fill and rinse cycles
• Eliminates intermittent or no-fill symptoms caused by broken wires, burned connectors, or loose plugs
• Maintains factory routing and connector fit for secure electrical connections

What's included: One water valve wiring harness as pictured Install notes:

• Disconnect power and shut off the water supply before starting work
• Handle connectors gently; match keyed plugs to their mating parts—do not force
• Inspect nearby components (valves, clips, grommets) and replace any damaged items
