Flip the brew toggle switch. Can you hear the pump?
- If No, try the following:
- If the pump does not come on, try to listen to see if you can hear a slight hum. If the pump is displaying a low frequency hum it is either under pressure due to a blockage, or the pump is faulty.
- If the pump does not activate at all it could be an issue with the brew toggle switch, a wire has come off the switch, a wire has come undone from the pump, or there is an electrical issue with the machine maybe due to a faulty control board.
- Also check to make sure that the machine is able to sense the tank is full and in place. If the light is not activated to represent this, then look towards the above section for troubleshooting the tank.
