Senseo won't fill itself on initial flush

allow tank to fill a little more by adjusting fill valve. When there's not enough water flowing from tank the stopper can over-power the water flow and cause the flush to stop by re-sealing.

No need to see what is in the manual.
But what I type here, you also have to read.
The manual gives pictures. I'm not.
Remove the transparent back of the machine and fill it with water. a few centimetres under the top, you fine the line for max fill.
Then replace the transparent back on the machine. Then plug in the power cord and press the power on button. (once is enough) a light comes on and flashes, when the mains plug has power.
Then wait till the light stops flashing. In the mean time put a coffee pad in the top and close the top all as described in the manual.
Place one or two cups under the nozzles and press the button with the one or two cups. (two cups gives twice as much water, so place two cups.

That is all.

Hi Have you tried to clean and de-scale it, limescale can really play havoc with these sort of devices. If you still have the instruction book give it a read and follow instructions for de-scaleing. Also there is a cleaning cycle on some of the models which just flushes the senseo through to clear it out again it is in the book but if I remember rightly you fill up the resoviour then turn it on and put a large bowl under the spout and press both the one and two cup buttons at once. But I would do a descale phillips say it should be done about every 3 months this should also clean out any other muck that has built up, they also say to clean out the pod holder including the little hole. The Phillips website has help if you have lost the booklet.

Check the power source to toilet and all wiring conversed.

If the tank is filling with water to the line level, and the flapper raises, and stays raised until tank is almost empty, when flushed then it must be a clogged line. Try a plunger (toilet snake) and/or call a plumber.

flapper needs to be adjusted or replaced

Flush it with a citric acid suspension:

• Fill the reservoir with the suspension,
• Place a large bowl under the spout,
• Press and hold the 2 small buttons, and
• Briefly press the Power button.

To stop the rinse, press the Power button again. I suggest you repeat the procedure a few times, remember to swap the pad holders somewhere in between.

Then repeat the procedure a few times with fresh water to get rid of the citric acid.

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

Yes, it is called descaling. Use a descaling solution, or vinegar and water, and follow the procedure for flushing your machine. After that, re flush it with plain water- nothing worse than vinegary coffee!

Try flushing the machine by filling the water tank with water and then pressing both the one cup and the two cup buttons at the same time (make sure to put a big enough bowl under the spout). If this doesn't work, give Senseo a call: 1-866-4SENSEO. They should be able to help! Good luck!
