How to Fix Your Senseo Machine

Left Back to Blog

Senseo makes a great coffee brewer. The machine makes fresh and flavorful coffee every time, but as with most any device, problems can occur, so it's good to know how to fix them. That's why we've put together a list of five common issues people have with their Senseo machine along with some quick and simple solutions. Don't waste your time and energy on easily remedied problems.

1. Light Blinks On and Off

Solution: Use a magnet to connect to the valve from the outside of the machine. Slide the magnet slowly upwards along the water level. This should stop the constant flashing and the water level should start to heat again.

2. Coffee Comes Out Watery

Solution: Add more coffee to your brew. It's really that simple! The machine is made to make a great cup of coffee, but a certain amount is needed to make a strong, flavorful, brew.

3. The Machine Will Not Heat Water

Solution: Unplug the machine and move the water reservoir out of the tray. Then pop the cover off the back of the machine. Chances are one of your heating wires have come loose, so you need to identify which ones. By looking into the back of your unit, you'll see four wires. These wires should be covered in a plastic wrap. If you don't see a plastic covering on the wire, you need to pinch it together with pliers then wrap it with electrical tape. This will allow the wire to once again conduct the flow of electricity.

4. How to Descale Your Senseo Machine

Solution: Fill the unit with white vinegar then put a pot or bowl underneath the spout. Next, press both the cup and two cup buttons at the same time. Run the vinegar through the system as if you were making a regular brew. Finally, run water through the system twice to clean out any lingering taste.

5. My Senseo Won't Complete Its Initial Flush

Solution: This issue may be fixed by simply making sure you've sealed the machine properly. Run a test by pushing the pin at the bottom of the reservoir and see if water comes out. If that's the case, then it's most likely an internal problem and you may want to contact Senseo customer service for additional troubleshooting help, or entertain the thought of a new machine.

  • Bought Senseo Type 6563 from Carrefour in Calais, a few months back, having tried one (in a BnB in north France), where the coffee impressed! The unit has been fine, but called for a descale thisa weekend. So we mixed-up the desaler fluid and followed the online instructions, which was not to interrupt the machines process, once the descaling was initiated. The machine pumped the tank of the fluid through itself and kept making the “pumping noise”. We did not interrupt it, but it interrupted itself by switching off and now will not swtch on. I have assumed that the unit has indeed failed through running “dry”. Can tyou confirm it there is any way of bringing this back into work please? We were very happy with it.

    Many thanks.

  • The Senseo user manual specifically says to only use citric acid based solutions, and to not use vinegar or any other cleaner based on mineral acids, e.g., sulphuric acid, sulphamic acid, hydrochloric acid, acetic acid (vinegar). Using any of these can cause damage to the Senseo. Either get some citric acid and mix it with water, or just use diluted pulp-free lemon juice.

  • re Top will not release. I left it a day (as suggested in another post) but it was still stuck. I used the back of a sturdy knife blade lengythwise to jemmy the lid open whilst holding the top to make sure it didn’t crack/split the plastic (also had it ‘unlocked’)
