Dishwasher shows H06 and does not complete the wash cycle

Safety first: Disconnect power and turn off water supply before tilting or removing the dishwasher.

• Listen for pump operation: Start a cycle and listen after filling. A loud humming with no water spray, or complete silence, points to a circulation pump issue.
• Check for obstructions: Remove lower spray arm and filters, then inspect the sump inlet to the circulation pump for broken glass, bones, or plastic pieces. Remove any debris with pliers.
• Access circulation pump: Lay the dishwasher on its back (with towels) and remove the base panel. Locate the main circulation pump attached to the sump.
• Inspect impeller: Remove the pump cover and check that the impeller spins freely by hand. If stiff or jammed, clear debris or replace the pump.
• Electrical test: With a multimeter, check the motor windings for continuity. An open circuit indicates a failed motor.

Replacing the circulation pump on Panasonic dishwashers involves water seals and electrical connections; if unsure, have a technician perform the replacement.
