1) Is there enough water in the water tank?
The water level needs to be above the minimum level.
2) Has the water tank been placed correctly?
Make sure the water tank has been placed correctly. Then check if the coffee machine functions properly, i.e. if the light ring starts to flash slowly.
3) Did the float in the water tank get stuck?
Empty the water tank and shake it a few times to release the float. Clean the water tank with hot water and some washing-up liquid.
4) Did you place the Coffee machine in a room where the temperature is below 10 degrees Celsius?
Please note that the Coffee machine does not work in rooms with a temperature below 10 degrees Celsius. Check whether the Coffee machine functions normally when it is used in a room with a temperature above 10 degrees Celsius, please let the appliance accommodate for 1 or 2 hours before retrying.
