    I have the same problem. I've rinsed using the suggested method approximately 8 times now and that has not solved the problem.

    I just received my new machine today, followed all the "first time use" instructions and it still keeps blinking. I have gone through the flushing sequence about 5-6 times now and still, not fixed.

  • Needcafenow Jun 15, 2008

    Same problem. Flushed it - and still happens.

  • kenneys Sep 26, 2008

    New machine same issues.  Have run the flush process several times to no avail.  Will try checking the float etc.  Have emailed their customer service as well but no word back as of yet.  May just need to exchange the machine as it seems to be a quality control problem (and at the cost of the machines shouldn't exist!)

My husband found in ours that the little float was stuck over the sensor (the little patch) down in the reservoir. The float could not rise with the water, thus, the machine did not know that there was enough water available and it would not stop blinking. He took the dry reservoir out, turned it upside down and shook it! This worked for him, as it unstuck the float. He said that if that doesn't work, the thing is really stuck and you might as well return it.

Hello everyone

Check the little float in the water reservoir. It might be sticking. This is a safety devise so the unit doesn't continue to run with no water. Use a long, narrow flat head screwdriver and place it between the float and the front wall of the water reservoir. Then immerse the corner of the reservoir in boiling water for about a minute. After a minute run the reservoir under cold water. Make sure the screwdriver is in place the whole time. Once the reservoir is cooled down, remove the screwdriver. This will reform the wall of the reservoir adjacent to the float and hopefully allow the float to move freely. If this doesn't work, you may need to buy a new reservoir.

    This worked well. I didn't have a long flat screwdriver, but a letter opened worked fine. It appears I caused the problem when I cleaned the tank with boiling water. Apparently the plastic shrank and locked the magnet float. Thank you very much.

    Hi, This was my problem too. The float was stuck, I released it and it worked. Excellent solution to a frustrating problem.

  • Anonymous Nov 18, 2017

    While doing this with the boiling water I noticed continuous bubbles coming from the black float. This obviously meant the float was filling with water, and indeed after the procedure it could move freely but would not float.
    I decided to remove the metal retaining clip and take out the float to study it. What do you know? The plastic was irreparably cracked at the top, due to oxidizing metal inside (a magnet?). I gave the now useless container an honorable burial in the plastics bin.
    No coffee tomorrow morning :-(

Mine does it when there's not enough water in the reservoir. There's a floater and the spout at the bottom. Make sure both are working.

I don't think the Best Solution #1 writer read the problems. We have all done that several times but it will not register that the FLUSH was done hence machine will not start making coffee. The mandatory flush cycle was a BAD idea. This thing will probably go back, poor quality-

Fill your reservoir with cold water, put a bowl under the spout, turn it on, and press the one and two cup buttons at the same time. This will flush the machine, and your blinking will stop and you should be able to make coffee.

I guess it's the metal part in the water tank that makes contact with the machine when the water runs out. When you take the water tank off the Senseo it's in the bottom right corner. If you can't repair it, a spare water tank isn't that expensive.

Descaling problems

Don't run the clean operation. Just put white vinegar/ water, half and half and run as if making coffee. Let it cool and run through about 3 times and this will remove all scaling/buildup.The rune through plain water.

The machine locks up and then when it heats up the water does not flow from the spout

Not sure what you mean by 'locks up', but if the slow flash changes into a steady light in the power button, 2 situations can occur in your case:
  • when nothing happens at all when you press one of the buttons: the button or the PCB inside the Senseo have failed.
  • when the power light starts slow flashing again: the pump motor has most likely died.
Either case requires contact with a repair shop . .

Light keeps flashing and water will not heat

there is a float at the side of the machine by the water level, if the float gets stuck the red light will continue to flash even though water is present. Use a magnet on the outside of the machine by the water and float level and raise the float when connected to the magnet and the light will stop flashing red rapidly

Senseo 7814 does not heat water and red light keeps flashing

is the red light flashing as though not enough water, if so use a magnet to connect to the valve inside the machine, the valve can be found along the water level where the float is. what is happening is that the float is stuck. by connecting the magnet to the valve and very slowly moving the magnet along the water level, upwards the valve will follow and the water will begin to heat as the light changes to a slow flash, if it doesn't work try again as you have not connected to the magnet

Decreased output from Senseo

I'm thinking it needs to be "Descaled" Heres info from

Does my Senseo® appliance need to be descaled? Yes. Descaling is an important element in Senseo maintenance. It should be done at least once every three months, up to six times a year!

Keeping your Senseo free of scale will:
  • Ensure you have maximum cup volume
  • Ensure you have maximum coffee temperature
  • Make your Senseo produce less sound while brewing
  • Prevent your Senseo from malfunctioning
  • Prolong your Senseo's life.
The descaling process takes about one hour and should not be interrupted. Only a descaling agent based on citric acid can be used safely in the Senseo. Other agents, including vinegar, may damage your appliance or not remove the scale entirely. If the procedure is not performed correctly, scale residue may remain in the machine. This causes scale to build up more quickly and may cause permanent and irreparable damage to the machine.

For the right procedure to descale your type of Senseo, see attached document.
