Dishwasher shows E8, often associated with poor water level or spray performance.

Safety first: Turn off power and water supply before inspection.

• Check spray arms: Remove and clean upper and lower spray arms. Blocked jets can cause abnormal pressure and confuse the water distribution system.
• Clean filters: Remove and thoroughly clean the coarse and fine filters in the sump to ensure proper circulation.
• Run a cleaning cycle: Use a V-ZUG-approved dishwasher cleaner or descaler on a hot program to remove internal limescale that can affect the diverter valve.
• Observe operation: During a test cycle, listen for clicking or switching sounds from the base area as the diverter changes position. Continuous loud clicking may indicate a jammed valve.
• If E8 persists: The diverter valve or water distribution assembly may need replacement, which requires accessing the underside of the machine. Contact a technician.
