Can I descale without taking out boiler by pouring in solution from the top of the boiler? Other question - there is a costant leak via the overflow pipe - does this indicate a problem with the 3-way solenoid valve?

Hi I have seen all ways to descale espresso machines on this and other sites and most are wrong! Never leave the machine heating while the descaler is in the boiler. It's OK for a few seconds but never for minutes or hours. It will turn your seals hard as a rock and the machine will start leaking. If your machine is leaking you probably left your machine on while it was descaling. Factory programs, if used do not turn the boilers on in the descale mode for this very reason. If your machine has a factory descale mode, use it. All factory descaling programs use the flow meter to regulate the descaling. The flow meter tells the computer how much water has gone through the boiler. when the machine is out of water the flow meter will stop turning and the computer knows the machine has used up all the descaler, and it will want to be rinsed. Remember the pump has to stop on its own for the computer to know it's done! Again the flow meter will tell the computer it is rinsing and when it is again out of fresh water it will tell the computer it is done rinsing and the descaling message or light will disappear. Remember the pump has to stop on its own for the computer to know it's done! It may say descale on some computers and there is a program for resetting the descale. It's in your menu as "Reset Descale". Choose "Yes" and push the menu button to lock. It's all regulated by your water hardness. I have mine set on 4 and my water is very good. I have over 20,000 drinks, and the original boiler. Saeco(Starbucks) Barista Digital. This method can be used on any espresso machine. 1. Remove the water tank and fill half way with fresh water. 2. Mix your descaling powder (Citric Acid or Durgol Never use Vinegar) in a glass of warm water. When dissolved pour into water tank. 3. Open steam knob. Have a large bowl under the wand to catch the water expelled from wand. 4. Turn on machine (automatics will cycle then start pumping water) Regular espresso machines you will need to turn on the brew button. 5. When the pump has expelled about 8 ozs through the steam wand turn off only the power button. Leave the other buttons and knobs alone. 6. Wait about 10 to 15 minutes for the descaler to work, then turn the power button on and run another 8 ozs through the wand and turn off the power button. 7. Repeat step 6 until the water tank is empty. (machines that have magnets in the water tank will not let you pump the water tank dry but they have programs built in to use that will) 8. Once the tank of descaler is empty, rinse out and fill with fresh water. 9. Open steam knob and run the complete tank of fresh water through the boiler without stopping, and once its complete refill with fresh water and your ready to go.
This means you probably have a leak inside. Usually the seals from not descaling enough. The steam boiler is over the power switch and will short the power switch. You can replace the seals in the steam boiler hoses, or tighten the fittings and probably save the machine, but change the water hardness setting in the menu to 4. This setting has saved many machines, but you mest descale your machine when it tells you. This also saves the machine.
HI Decalcifying your boiler: Your boiler uses water that has dissolved minerals in it. Even if it is filtered, there are minerals. Your boiler needs to be decalcified to prevent mineral deposits from damaging it. Why can this damage your boiler? The boilers within these machines are small and narrow and therefore they heat up quickly. They hold a small amount of water (250 ml). Their heating element is in the boiler housing itself. So when you start to accumulate mineral deposit, you take up space. This lowers efficiency for heating. Also the mineral starts to attack the silicone gasket that seals the boiler and soon you have a leaking boiler. Water hardness is measured in numbers from 1 to 4. Number 1 indicates soft water having a few minerals while Number 4 describes water containing the most minerals. Set your water hardness to 4 is my recommendation to keep your boiler in good working order. Descale more often than not enough! To program the water hardness into your machine, press the scoop coffee button and hold until you get the menu. Scroll through the menu until you come to water hardness. Set your water hardness to the level that your test strip says. Press enter (scoop button). Use the arrows to select the hardness and then press enter. You have programmed your hardness and now the machine will tell you when to descale. 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 down 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.
On your machine, the leakage is the seals on one of your 2 boilers. One can be fixed the other will have to be replaced depending on which one is leaking.
Hi Leaking under the machine usually means 1 of 2 things. You have a ruptured hose or your boiler is leaking. Both are repairable. There are 2 types of boilers in the Saeco machines depending on its age. The newer machines have a stainless coiled tube in an aluminum heater. This would probably be a hose. The older boilers were a 2 piece with a gasket that will leak if not taken care of by descaling on a regular basis and done correctly. No excessive heat when descaling. Turn the machine on, then run descaler through the wand by opening the knob for water. Run 8 nozs through the wand then turn the machine off and let it set. Do this until the descaler is gone. The rinse with a tank of fresh water.
Hi More than likely the boiler is leaking from improper descaling. Seals do not dry out but they will become hard and brittle if you descale while the machine is hot. I would say you need your boiler replaced. Another thing that will make your boiler leak is not descaling it on a regular basis.
Hi Boilers leaking are usually a sign of not descaling enough. It is not recommended to take apart your machine unless you have knowledge in electronic repair. There are a lot of wires and hoses. Once the boiler starts leaking it needs to be replaced. email me for directions since it won't fit on this page.
I had the same problem with a Saeco Royal Digital. I ran the decalcifying liquid through the machine with the automatic descaling program as per the instructions on the bottle and the DECALCIFY message stayed up.
I solved it by going to the menu and selecting "Signal Descal." and toggling it from No to Yes. I escaped back to the menu and git the usual "Select Product".
Hope this helps.
