<!-- from fixya rte -->Pump not working after descaling - Nespresso Essenza C100 Espresso Machine/Coffee Maker

Yes it sounds like the pump is clogged with scale.

Syntia and Brera machines are made by Saeco. Brera is marketed under the brand name Gaggia (owned by Saeco).
The causes for this malfunction can be due to following in order as stated:
1- The machine was not descaled or it was descaled using products. that are labeled as descaler but they are not. After extended period of not descaling, one may have to use more than one cycle of descaling to remove accumulated depsits of Calcium in the water system.
2- The grind setting of coffee is too fine. Make it coarser by one notch toward coarser setting at a time.
3- The pump is losing its pumping pressure and not pudhing water through the coffee. Replace ULKA pump with an Invensys pump model CP3.
All fully automatic machines are convenient and make classic shots of espresso from bean to the cup at the push of a button. With this simplicity, owners forget its maintenance until machine stops working. Please pay attention to descaling every three months. No excuse is good enough.

Hi
Yes it may need descaling - deposits like calcium etc from 'clean' town water will build up in the machines boilers and tubes over time - that's why we descale them regularly - even if they don't get a lot of use.
Suggest you get some proper descaling liquid, not vinegar or CLR, read the manual on how to do it (download it off the net if you don't have it). ( it takes a little while as the descaler has to eat away those deposits and the machine will pump a little water out, then wait for a while, pump a little more etc until its finished the process)
Make sure your filter in the coffee dispenser handle is clean as coffee itself will build up and block those tiny holes if the machine is not porperly cleaned each day when used.

I suggest you try cleaning/descaling again. Possibly the scale that was loosened did clog the coffee maker up.

If you can hear the pump running, I would say you have some blockage in the line

Hi
To descale your Magic Comfort +, enter the menu and scroll to descale. Push the menu button to descale. Mix your solution in your water tank. Use warm to hot water and dissolve all the solution. Place the water tank on your machine. With a container under the steam wand that is large enough to catch all the water in the tank, you are ready to begin. To start the descaling process, open the steam knob. The machine will automatically start the descaling process and when it is finished, it will shut off and tell you that it needs to be rinsed. Remove the water tank and rinse with fresh water. Refill the water tank and place it on the machine. Turn off the machine, wait a moment, and then turn it back on. Press the hot water button to start pumping fresh water through the boiler. Pump out about 16 oz. of water and then turn off the hot water button and open the steam knob to rinse the steam boiler. When it starts to go to steam, turn off and turn on the hot water button again. Pump out another 16 oz. Repeat this process with the steam knob until you have emptied the water tank. Descaling is complete. Go to your menu and scroll to "reset descale", push the enter button and chose "Yes" and push the enter button. Now it will tell you we next to be descaled.

pump keeps running - again this is indicative of a dirty / scaled saniflo. You need to clean / descale the saniflo. if this does not work then an outlet pipe blockage (22mm) may have occurred (unlikely if the unit is operating ok). Saniflo sell their own cleaner, which can be introduced via the wc bowl. If this does not work, then its time for a proper clean ( remove unit, jet clean, acid descale, wash, replace). Obviously not everyones cuppa tea.

Hi
Have you tried to descale your machine. Remember to use the correct descaling powder and make sure that it is totally dissolved before running the descale program. In the menu, make sure that your water hardness is set on 4. descale more often than not enough.

Try descaling the machine. Saeco has a suitable solution, although the user manual says 'you may use any commercially available non-toxic descaling agent.' The instructions are set out in the user manual, and are usually on the descaling agent label. It is important to descale regularly, at least every 4-6 months.
