Dishwasher shows E9 and may stop with water remaining in the tub or base.

Safety first: Disconnect power and close the water supply.

• Check spray arms: Ensure both upper and lower spray arms rotate freely and are not blocked. Remove and clean jets under running water.
• Listen during wash: If you hear intermittent clicking or the spray pattern seems wrong (only top or bottom washing), the diverter may be stuck.
• Access diverter: On many Baumatic models, the diverter valve is integrated into the sump or circulation pump outlet. Remove the bottom cover and locate the small motor/valve assembly with wiring.
• Inspect for obstruction: Check for debris around the diverter mechanism. Remove any foreign objects carefully.
• Replace diverter: If the motor does not operate or the valve is physically damaged, replace the diverter valve assembly. If E9 persists after replacement, the control board may require service.
