Machine stops with E6; no circulation, no spray pressure, dishes remain dirty.

Safety first: Isolate the dishwasher from power and allow water to cool.

• Check for obvious blockages: Remove tank filters and inspect the pump intake area for broken glass, labels, or other debris. Remove carefully.
• Listen for pump operation: Restore power and start a cycle. If you hear only a humming noise or nothing at all when the wash phase should start, the pump may be seized or electrically faulty.
• Check spray arms: Remove and clean upper and lower spray arms to ensure they are not blocked, which can overload the pump.
• Professional repair: If E6 persists, the wash pump or its capacitor typically needs replacement. This requires access from the machine base and should be done by a qualified technician.
