Machine will not stop descaling process, over & over.

Try disconnecting the power overnight to try and reset.

You need to enter service mode and reset the descale - to enter you press the hot water and power button at the same time and releasing - then press hot water five times and hold - there you can reset the descale

Hi,
Fill it up the tank with descaler and start the machine on descaling. Leave it to trow all the liquid and must finish to the bottom,leave the machine to get AIR when descaler finished.Then the machine will stop and will tell you to put fresh water to clean . Fill the water tank to the MAX level and continue with the program. When the water is on minimum ,machine will stop,and the descaling process must be finished.
Good luck

Hi,
been talking to Gaggia (Philips) and they told me that with the newer Breras, you need to ill the water tank, put the machine into standby, then press the long and short cup buttons together for 6 seconds. This will start an auto descale programme (that they didn't mention in my manual!). A small amount of water will be dispensed through the coffee nozzles, then it will stop and the warning triangle and the prime warning light will come on. Place a large container under the panarello, then turn the knob to the right to dispense water. It will dispense about 50 - 100 mls (cold) water, then stop for about a minute. Just leave it and eventually it will empty the tank. Refill it and start again, but it will stop after a few seconds. Turn the knob back to central position, then it will dispense another small amount of water from the coffee nozzles, then stop with warning lights again. Turn the knob back right to dispense water, if it stops because of empty tank, just refill it. Eventually, the machine will stop and go to standby. Turn the knob back to the centre, refill tank yet again and the machine will start normally WITHOUT that descale warning light. HOORAY !!

I have the same problem with my Delonghi Magnifica, so maybe there is a glitch in the machine..

Hi Auto descale: To automatically descale your machine, press the scoop button and hold it down until you enter the menu. Use the arrows on the left to scroll up until you come to Descale. Press enter 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.
