Dishwasher displays F5 and may not circulate water properly.

Safety First: Turn off power at the breaker before accessing the sump or lower spray arm area.

• Listen for pump operation: Start a cycle and listen. If you hear filling but no strong spray noise, the circulation pump may not be running.
• Check filters and sump: Remove lower rack and filters. Inspect the sump for debris (bones, glass, labels) that could jam the impeller.
• Inspect lower spray arm: Ensure the lower spray arm spins freely and is not obstructed by tall items or utensils.
• Power reset: After clearing debris, restore power and run a short cycle to see if F5 clears.
• When to call for service: If the pump hums but does not spray, or is silent, the circulation pump assembly or its wiring likely needs replacement by a technician.
