Question about Bosch Benvenuto B30 Espresso/Coffee Maker

2 Answers

Hi...i have a Siemens s40 surpresso which i believe is identical to the Bosch B30 machine. ive had it for years now and about to his 9000 brews! But the problem is that the water pressure is decreasing now and im told that there could be a problem with the pressure valve?? at times it pumps, little coffey comes out of the spouint and most goes inside into the dregs / water tray, so somewhere the pressure is causing water to pump elsewhere. The pipes are not blocked... im writing as this machine does not have service centre where i live... Thanks In advance...

Lovejoyone--Neither of the sites referenced in your post ships outside the EU. I own the Bosch B30 (5 years/10,000+ brews) which is in need of some rebuilding. I can't find ANYWHERE where I can get parts for this unit. Any suggestions?

You have to either get a new drainage valve or buy a "DIY" set
or the big set - you can just as well change all o-rings while you are at it.

I would also change the grinding stones (or whatever it is called in english...)

Alternatively buy the stuff at http://www.juraprofi.de/ - Komtra does not provide creditcard payment option.

Have a look at their forum - it is in german - but you will find an answer to all your issues with this machine.

    Well - if you cant get the parts you can try to clean and descale the drainage valve inner parts and put silicone grease (food grade...) on the old o-rings (and other rubber rings inside the valve - not sure of the name in english....) This could solve the problem - it is worth a try. Did you ask Jura Profi if they could send to non-eu countries?

    I do not know where to buy parts apart from the sites I mentioned. But try to google.

Bosch benvenuto b30 had for years and loved. Now when use beans the coffee/espresso is too watery and pucks are like sludge after. Works good when use preground coffee .


You have accidentally turned down the brew strength selector, on front of unit just above "clean" and "descale" buttons. Dial it the the maximum. Will grind longer, make more grounds, larger puck, stronger coffee. Or this dial is broken/ wire broken etc. u can disassemble per some other posts on here and check wire connections. I did all that then realized someone had just turned it down. So I turned it to maximum strength and problem fixed.

We have a Siemens Surpresso S40, giving 'error 8'


Error 8 indicates a technical fault. Try switching off the main switch for about 1 minute and then start it up again. If the error message persists, you will have to have the machine serviced. The most common fault would be that the machine is blocked.
