Dishwasher shows E08 and water level appears too low; spray arms may not rotate properly.

Safety: Turn off power and water supply before servicing.

Steps:

• Check water pressure: Ensure the household water pressure meets Gaggenau specifications. Fully open the supply tap.
• Clean inlet filter: Remove and clean the mesh filter in the inlet hose as described for other fill errors.
• Inspect side water matrix / heat exchanger: Remove the left side panel (on many models) to access the translucent water matrix. Look for heavy scale or debris restricting flow. Rinse with hot water and descaler if removable.
• Check spray arms: Remove upper and lower spray arms and clean all jets. Blocked jets can mimic low water level by reducing spray pressure.
• Test circulation pump: Listen during wash: a loud humming with little water movement suggests a failing pump. Access the base, inspect for obstructions in the impeller, and test the motor windings with a multimeter.
• Replace faulty components: If the circulation pump is weak or the water matrix is heavily clogged and cannot be cleaned, replace the affected part with the correct Gaggenau assembly.
