The indicator light of my SENSEO® coffee machine flashes

If the indicator light of your coffee machine is flashing rapidly, check the following solutions:

Too little water
Make sure that the water in the tank is filled above the minimum level

Water reservoir is not place correctly
Check the positioning of the water reservoir to make sure that it is attached correctly to the coffee machine. Refer to your user manual for further instructions. 

Float fell in the water
Check whether the float is stuck in the water reservoir. Empty the water reservoir and shake it a few times to release the float (see image for an example of the water reservoir float).

Water reservoir is dirty
Clean the water reservoir with hot water and some washing-up liquid.

Room temperature is too low
Make sure that you place your SENSEO® in a room where the temperature is above 10°C. Let the coffee machine adjust for 1 or 2 hours and then try again.

If the above suggestions did not help to solve your problem, please contact us.

A slowly flashing indicator light means that your SENSEO® coffee machine is still heating up. Please contact us if the indicator light continues flashing slowly for more than 90 seconds.
