Schaerer Coffee Makers & Espresso Machines - Recent Questions, Troubleshooting & Support

Is stuck in a Spanish mode and it says soon to be clean but it won't go back into regular mode

The water flow error and ST-Boiler error on your Schaerer Coffee Soul 10 may be caused by a variety of issues related to the machine's water flow system or electronics. One possibility is a blockage or restriction in the machine's water line. The water line can become clogged with debris, which can restrict the flow of water and cause the water flow error. You mentioned that you cleaned the blockage where the water line connects to the machine, but it's possible that there may be additional blockages further in the water line or in the machine's internal components. Another potential cause of the error is a malfunctioning level probe in the steam boiler. The level probe is responsible for measuring the water level in the boiler and controlling the heating element. If the probe is malfunctioning or the connection is loose, it can cause the ST-Boiler error and the water flow error. The level probe and its connections should be checked to ensure that they are securely attached and functioning properly. Other possible causes of the issue could include a malfunctioning solenoid valve, a defective flow meter, or a damaged pressure switch. These components all play a role in the machine's water flow system and can cause the water flow error if they are not functioning properly. It's recommended to contact a qualified technician to diagnose and repair the issue if you are unable to identify the source of the problem or if the issue persists after troubleshooting. They can use specialized tools and knowledge to diagnose and repair the issue to get your machine back up and running properly.

Question edited to throw in a few capital letters for 'proper names'. There is either a leak in the water inlet valve, plus worn o-rings in the brew head. These machines require a lot of ongoing maintenance. It isn't a machine I know, I have have used many commercially, but there is help here. https://www.google.com/search?q=Schaerer+Coffee+Art+Plus+leaking ..

Maybe studying "Communicating" would help

See if this manual for your maker helps:

Sounds like the machine is being starved of water. Is this machine fed to a water tank or plumbed direct to a mains water? When descaling a plumbed schaerer machine, you will need to remove the screw plug located where the tank inserts into the body of the machine, otherwise the descaling solution has no way to flow to the boilers to descale them. This is usually a flat head screw that sits in the center of the brass plug inserting into the back of the water tank. Photo below. This is quite common. I hope this helps.

Sounds like the overheat stats on the boiler are burning out. Check the Klixons and replace, also the wiring connections to the boiler can sometimes get burnt out and require recrimping.

Defective Software revision. Needs to be updated to the latest release

Machine Needs a software update. You can reset the machine by rebooting from the main power supply and if this doesnt release it. Try hold down the cleaning button for 10-15 seconds. Would need to know the software Rev and have a technician update it to the latest.

This is quite common on steam boiler when the level probe is not reached within a specific period of time. Reason is due to limescale buildup which restricts water flow... You need to remove and descale the fill pipe to the steam boiler. If its very badly blocked, you can drill out the blockage with a 7/8mm drill bit and then leave it soak in descaling solution until its clear and you can blow through it. Also you will find a small restrictor between fittings somewhere back from the fill pipe (between the fill pipe and the fill valve). This is a small disc shape with a 0.8mm bore in the centre, you'll need to check that this is clear also, they are notorious for blocking up due to small size. You can clear this using some very fine wire or if you have the Schaerer expander baffle pen. Be careful not to lose this restrictor when loosening the brass fittings as it is extremely difficult to find if you drop it into the machine. Good luck
