The machine does not drain at the end of the day; standing water remains in the tank after pressing drain.

Safety first: Turn off power and allow water to cool before reaching into the tank.

Step-by-step checks:

• Confirm drain procedure: Verify that staff are following CMA’s correct drain sequence (button or switch) for the model.
• Clean screens: Remove and clean all scrap and drain screens to restore flow.
• Test drain actuation: Listen for the drain solenoid or pump when the drain function is activated. If silent, test the component and replace if failed.
• Check building drain: Ensure the floor drain or sink is not blocked, causing slow or no drainage.

When to call a technician: If the drain mechanism is operating but water still does not leave the tank, internal plumbing may be obstructed and require professional service.
