Rancilio Popular Questions, Answers, Tips & Manuals

Question edited for clarity. Service manual in the link. Test water temperature and pump pressure. These machines need servicing every 6 to 12 months depending on use. https://www.google.com/search?q=rancilio+class+10+espresso+machine+service+manual ..

Often these temperature differences are solved by descaling. Do never use vinegar. One can buy citric acid crystals or powder (not the same as lemon juice) and dissolve that chemical in water. I buy it in the Chinese Mall. Do not make a too strong acid. Shops sell maintenance powder which is the same but that is quite expensive. Let the acidic water go in and through the coffee maker until it looks clear. Next rinse with water for quite a number of runs. You may see how strong the citric acid that you make is by descaling something else and wait for about an hour. Another acid to be used in coffee makers is lactic acid. Lactic acid is bought as a cleaning agent. Also very strong and to be diluted with water.

Question edited for a lot more clarity. Did you try a Power Reset so that the internal software operating system reloads? Pull the mains plug. Wait 10 minutes. Press and hold the Power button for 2 minutes to dissipate main board power. Plug back in and turn on. If that doesn't work, phone them up. https://www.google.com/search?q=rancilio+classe+10+no+software https://www.manuals.ca/rancilio/classe-10-sde/manual?p=128 ..

Tis Iron sediment keep running water thru it it'll clear up. If there's any way to run some vinagar thru it that would help greatly.

From your description and info replace valve.

My guess is the steam wand is clogged with milk. This is a common problem. Try a pipe cleaner or something similar.

Your pressure steam is more 1.8bar. Either pressustat defective or the safety valve

First, I'm not a Rancilio tech but I have worked on similar models. *** All service should be performed by a qualified technician. The following is for information only *** * Usually one gets less water out of the portafilter rather than more (or faster). Check the amount of water on an empty shot. It should be between 1-1/2 oz to 3 oz (depending on your shot size) If this is a manual on/off shot then disreguard. * Fast pour is directly related to the pressure setting (usually 9 bar), Coffee amount, Grind size, and Tamp (or compression). You can check most of it by following the many examples given on you tube. Water pressure is a bit harder as you will need a pressure guage portafilter. * If your still having problems with fast shots then have your service vendor check and adjust the bar if needed. Aloha, ukeboy57 P.S. Check if your using the right portafilter, There are many types used for different purposes; Pod, Capsule, Single, Double, Tripple, Drip coffee (Americano), Back pressure adjustable, ect.

"leaks noisily from what appears to be the contact between the grouphead and portafilter" * Leaks from top of portafilter and group head are caused by poor sealing at head gasket. * wipe top lip of portafilter before inserting into group. * check if group is clear of coffee grounds, paper bits, tissue, dry crud. Use a head cleaning brush (tooth brush works) and wipe group clean (do not use screwdriver to scrape!) * Make sure when inserting portafilter it is seated properly. (check your manual for procedure) Note the position of the portafilter handle if it's in the right position AFTER you tighten it. Is it far to the left? or stuck and barely hangs on to group? * Barely hanging on to group? Check if pod is too big. Note; you can't double shot or use 2 pods in a single pod basket! Make two separate shots for a double. * Handle tightens but slips off group or still leaks when pulling shot? Worn out or missing gasket. Gaskets are made of rubber and can crack, drop out, or pit. You will need to have the gasket replaced. Check with vendor or MFR for service/parts. * Make sure you have the correct portafilter. Many look the same and may even fit but when making fine adjustments or critical shots they don't work right. Check manual or vendor for confirmation. * Make sure you have the correct basket. The portafilters may have different baskets or cups that can be inserted. Many have special uses that can affect the pull of a shot. Fewer holes causes slower flow and longer brew time. Many holes gives a weaker shot but smoother less bitter taste. There is a blank basket that has no holes which is used for backflushing and cleaning of the group. Check your manual or vendor for which basket you should be using. Odds are that you have a standard basket ment for ground coffee and not pods. (you can remove the coffee from the pod but it will be messy.) Ask for the optional 'POD' basket insert. * Finally if everything checks out and your still having leaks then your machine needs service as the group head or valve needs replacement. Call your vendor or MFR direct. Aloha! ukeboy57 (youtube) P.S. Looking back at my service with pod conversions, I've found that most if not all pro-machines don't really like the pod adapters. Sure it will work but shots are weak and poor. Pods really like a very tight fit with a very small portafilter basket(chamber) I mean like the size of a soup spoon! They like very slow and very hot water pumped with a vibration type pump to extract all the essence from the paper filtered coffee. Illy is an excellent coffee pod with a very rich aroma and good creme. The best for them (pods) are the dedicated pod machines (won't do ground coffee, only pods). If you must use a pro semi-automatic machine then I would suggest adding a port constrictor to the portafilter output. There may be a third party supplier that has a compatible adapter for your brand. I've come across some of these very extreme tools for the elites coffee affectionato. It restricts the flow at the output thus causing the hot water to brew longer and at a higher pressure to force the hot water and steam into each coffee grain. (think pressure cooker) Some of the better ones are adjustable. But note that these will need daily or cleaning after each use as these restrictors have very tiny holes which clog unless flushed after each use. Good luck 9on your pursuit of the perfect cup!)

Hi Ewah, If you are getting steam from the group and no water when you turn on the water button - then you may have a group blockage. The fix depends on the type of machine you have. If it is a commercial type - then call in a qualified coffee technician. If it is a domestic type like rancilio sylvia, the you could try to descale - maybe too late, but worth a go.JURA descaling tablets If when descaling, no water is coming from the group try leaving the steam tap open when asking for water.That way you may get the descaler liquid moving inside the boiler and it may clear the solenoid valve blockage. If no joy with that you may need to replace solenoid valve. 230V 9W PARKER SOLENOID Domestic machines need regular descaling to avoid group blockages.

Have you tried to hoover up the grinds from time to time, from the grinder blades. The coffee beans and ground can gather under the blades from over time. It should not be a problem though. For better crema you may want to replace the blades.You should replace every 3-6 years. Rancilio Rocky Grinder Flat blades

Hi Daren, You could replace the whole steam valve wand but you don't need to. The rubber grommet inside the steam valve is worn out and the tap wont close properly - that is why the steam is coming out. You will find these parts with a commercial rancilio supplier.

You need to contact a coffee technician that deals with Rancilio commercial machines.They would be able to trouble shoot. But it would involve a call out to investigate the problem.

Rinse the machine with Baking Soda solution (2 to 4 quarts). Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edward_bbd2c7ff4ee1828a

Heating element is possible damaged causing grounding. Remove top panel and using ohms meter check resistance.

It is possible that the grind you are using is too fine and causing so much back pressure that the portafilter is moving, also possible that the group gasket installed need to be replaced, I have also seen this happen with damaged screens.

the tank is rusting

Honestly, no idea, bu you can check user's manual http://expert-cm.ru/images/stories/shemy_tehnich/tech_silvia.pdf and watch this tutorial video How to make cappuccino on the Rancilio Silvia Espresso Machine Might give you some clue? Alos, have some interesting information about your machins ' CoffeeGeek Rancilio Silvia Espresso Machine

Some GFI use spark detection and if you have one of those, you need a new gfi. IF not then you have current leakage in the grinder and it is dangerous to use and should be replaced.
