My machine shows message: Clean/Ready. I followed all the steps in the operating instructions. Machine was on, water tank full, pushed Rinse button, display showed Empty Tray. Removed tray & emptied it. Put it back. Pressed Rinse. Display showed Cleaning BUT NEVER SHOWED ADD TABLET. Next display showed Ready, so I was never instructed to add tablet therefore never went through cleaning cycle. HELP!

Over time, the continuous heating up of the water used to make the coffee leads to lime scale building up in
the inner circuits of the appliance.
When the appliance displays the message:
DESCALE
you should perform the descale cycle.
Proceed as follows:
• make sure the appliance is ready.
• press the button (the light over the button comes on) then press the button repeatedly until
the appliance displays:
DESCALE No
• Press and the appliance displays the message:
DESCALE Yes
• Press the button to start the descale programme.
• Empty the water tank and add the contents of one bottle (125 ml) of DURGOL descaler plus
one litre of water. For subsequent descaling, use descaler of the same type and brand as supplied
(available from technical service centres authorised by the manufacturer).
• attach the water spout to the nozzle;
• place a container with a minimum capacity of 1.5 litres under the hot water spout (Fig. 3);
• press the button. Descaler runs off from the hot water spout into the container below. The appliance
displays:

• the descale programme automatically performs a series of run offs and pauses to remove lime scale
deposits from inside the coffee maker.
• After about 30 minutes, the appliance displays:
RINSING FILL TANK
The appliance must now be rinsed through to eliminate residues of descaling solution from inside the appliance.
Proceed as follows:
• empty the water tank, rinse and fill with clean water.
• Reposition the tank.
• Empty the full container and then put it back under the hot water spout.
• Press the OK button. Hot water is run off from the spout into the container below and the appliance displays:

• The descale programme is now terminated and the appliance is ready to make coffee again.
NOTE: if the descaling cycle is interrupted before completion, the appliance continues to display the descale
message and the programme must be started again from the beginning. Empty the water tank, rinse, fill with
clean water and run off a cup of hot water.

Try doing another rinse cycle until water tank empties. I had to do that a couple of times, then the red exclamation mark came on. Then I turned knob to off position, refilled water tank, pressed the descale button for 6 seconds, green light came back on and it did its priming.

Have you had the same message for a while, but were able to make coffee? When was the last time you decalcified the machine? Your Syncrony probably needs to be decalcified. But do not use the descalers you usually find in the grocery stores, which are for drip coffee makers. Durgol is one of the best ones and the advantage is that it comes as a liquid (on the powder descalers you have to make sure they dissolve completely before you use them and that you measure the correct amount of water). You can find it online or the only store I could find that carries it is Bed, Bath and Beyond. Turn the machine off and let it cool off. When you are ready, take the water tank off and add the decalcifying solution mixed according to the instructions on the package. If you are using a powder, mix it in a different container. And never pour the solution in the tank while this is on the machine (also, make sure the coffee beans container has the cover on - you don't want any liquid making it into the grinder, as it will damage it). Put the water tank with the descaling solution back and turn the machine on. You will then have to press and hold the button that looks like the number 8 on the side (or the infinity symbol in math) and the machine will start the descaling process. Follow the instructions on the display. Put a large container under the steam wand and turn the knob (the same knob you turn for steam and hot water). Be sure to watch for when descaling is done (you will have a message on the display indicating that). Close the knob, rinse the water tank well, fill it with fresh water and put it back on the machine, which will now need to be rinsed. Place an empty container under the steam wand and push the same (8 on the side) button once, turn the knob. The machine will start the rinsing process. You might have to refill the water tank once or twice before it is finished. Once rinsing is done, your machine will be ready for use or it will ask you to ventilate. To do that, fill the water tank with fresh water, place an empty container under the steam wand, push the hot water button and turn the knob. Let the machine circulate water through. Once the ventilate message is gone you're done.

Hi
Your showing a different machine than a Royal and that one is different, but if yours is a Royal, this is how.

Auto descale: To automatically descale your machine, press the scoop or menu button and hold it down until you enter the menu. Use the arrow buttons to scroll up until you come to Descale. Press enter button and the machine will enter the mode to descale your machine. The process takes about 45 minutes. You don't have to do a thing except mix a full water tank with descaling solution and have a container under the steam wand when your start. If you have a cappuccinonatori on your machine you will need two containers. To start the descaling process, simply turn the steam knob. When the process is over your machine will say "Descale finished". Remove your water tank and rinse it out. Refill it with fresh water. Replace on the machine and start the descaling process over again to rinse your machine. Go back into your menu and scroll up or down 1 to signal descale and enter. Choose "Yes" and push enter so the machine will tell you when you need to descale again.
Manual descale: To decalcify your boiler, remove your water tank and fill it with hot water (100 to 120 degrees). Open a pack of decalcifier and mix into the water tank. Place the tank back on the machine, then turn the machine on.

1. If you have a non-rapid steam machine, just open the steam knob and run approximately eight ounces of solution into a spare container. Turn the machine off and let set about 10 to 15 minutes. It is very important that the machine does not remain on to heat the boiler anymore than necessary.
2. If you have a rapid steam machine, turn on the machine and then push the hot water button. This turns off the rapid steam and allows you to run hot water/solution through the steam wand. Just open the steam valve and run approximately eight ounces of solution into a spare container. Turn the machine off and let set about 10 to 15 minutes.
3. Repeat step #2 for your type of machine. Do this until you have used the entire water tank of solution (approximately four to five cycles). Remove the water tank and rinse it with fresh water.
4. Refill the water tank with fresh water and place it back on the machine.
5. Repeat step #2 to rinse the machine, only this time use the entire water tank at one time, and there is not need to let it set.
6. Your machine has been decalcified. You may still have scale in your boiler, but not as much as you had before. To reset your descale light, hold down on the steam button for at least five seconds. You are ready to brew, once your boiler has heated up.

To clear the descale message, push and hold the steam button for 5 to 10 seconds. It will clear.

Hi
Go to your menu in the machine. Use your up arrow to go to decalcify and push enter. Have your solution for decalcifing the machine mixed in your water tank. Have a large container under the steam wand and cappuccinator on the left. Then open the knob for steam. Machine will say "Machine descaling". It has to finish the whole tank before it says "descale finished". Now rinse the water tank and put fresh water in it and put back on machine. Now close knob and then reopen it. Machine will say "Rinsing" When that tank is gone, it will say finished. Put water in tank and then go back to your menu and go down 1 to reset descale. push enter and chose "Yes" and hit enter to lock it. Now go down to water hardness and hit enter. Cahnge the # to 4 and hit enter. Push the escape button 2 times and your back. and ready to go.

You need to descale the machine with descaling solution.
