Rocket Espresso Machine Light Blinking
We get many service calls due to the green light on the front of the Rocket Espresso Machine Blinking even thought there is water in the tank.
The light starts blinking when the machine thinks there is no water in the tank or the tank is not sitting firmly in the machine.
The sensor responsible for this measures a small current going thru the water. Regular Water is an electrical conductor. If water is treated with an RO system or water is going thru the "ZERO water jug" or distilled water is used, the water is no longer a conductor as the water has zero TDS and the sensor thinks there is no water.
Try adding a cup of regular untreated water to the tank so the sensor can measure the water level again.
You can also add our third wave formulated water powder to the water tank for best results.
