Dishwasher shows E9 and may stop with water in the tub; sometimes accompanied by unusual noises from the pump area.

Safety first: Disconnect power before accessing the base of the appliance.

• Observe symptoms: If the dishwasher cleans only one rack or makes clicking noises before E9 appears, the diverter valve may be stuck.
• Access diverter assembly: Remove the base cover and locate the Sharp diverter valve attached to the sump or circulation pump outlet.
• Check for obstructions: Inspect the diverter housing for debris or broken plastic pieces that could jam the mechanism.
• Test motor movement: With the machine disconnected, manually rotate the diverter (if possible). If it is jammed or the motor is burnt, replacement is required.
• Replace diverter: Install a new diverter valve/motor assembly. Ensure the wiring connector is firmly seated and the seal to the sump is watertight.
