Question about Bosch Benvenuto B20 Espresso & Coffee Maker

2 Answers

"water pipe empty" icon will not disappear from display screen 3, cannot brew coffee, first use - second machine to have this problem

For some reason, the people at the Bosch hotline have not been able to help at all with this problem. This is the second of 2 B20s that we have purchased, after having to return the first one because of the same problem getting it to brew coffee even one time. The instructions are so simple as far as setting the machine up. We are using bottled water, so I was told no filter was necessary. Water is in the tank (below the "max" fill line, but above the minimum necessary to float the magnet), water hardness selected (1), beans are in the hopper, all the dials on the front are in the proper position to brew a cup of coffee, the voltage requirements have been met, machine is plugged in and turned on using the power switch on the back. The machine shows an illuminated ring around button 4 and nothing else. Then, when button 4, the power button is pressed, the machine sounds like it is gearing up, and the "water pipe needs to be refilled" icon (also called the "rinse" icon in the manual) appears in display screen 3, along with a blinking ring around the "cafe" button 5 (around button 4 remains an illuminated ring). According to the manual, to resolve this problem, one is supposed to press button 5 ("cafe" button) and the pipe is supposed to refill. There is supposed to be a coffee cup icon that appears in display screen 3 indicating that the machine is ready to brew coffee. AT NO TIME DOES THE COFFEE CUP ICON APPEAR IN SCREEN 3, nor does the "water pipe refill" icon ever leave screen 3 (unless the machine is put into standby mode). When "Cafe" button 5 is pressed, the illuminated ring around button 5 turns off, and the illuminated ring around button 4 (power/standby) button begins blinking. The "water pipe needs to be refilled" icon remains in screen 3. If nothing is done at this point, after a couple of minutes, the machine reverts to illuminating a solid ring around button 4 (power/stand-by button) and a blinking ring around "cafe" button 5. I had thought perhaps someone had been inserting the magnet in the water tank backwards during assembly, causing the machine to be unable to detect the water in the tank. So, I ordered another water tank for the machine to test this theory. This tank produced the exact same result. Additionally, this is the SECOND machine we have tried this on - BOTH machines producing an identical result. Perhaps it is the sensor on the inside of the machine sensing the magnet- who knows? Please help. This will be the second one to be returned, and the people at Bosch can only troubleshoot things that are indicated in the manual (basically read the manual to me). THANK YOU!

    Thank you so much for posting a similar problem with this thing. I was starting to think maybe I had gotten the only 2 machines that this was happening with. The people on the hotline repeatedly insisted that "they are very easy to use" and "no one ever calls about them" - which is why, I suppose, they didn't know much about them. I spoke to that same "expert" and nada. All he did was run me through the same explanation in the manual. I returned the thing, and got a DeLonghi. I totally recommend this one. Thanks again for letting me know mine weren't the only ones. :)

    Well, these posts are dated mid 2007; it's now almost June 2008 and I have just received a brand new B30 (this morning) with exactly the same problem. The unit will not start; right out of the box. Exact same error messages and flashing lights. Upon hearing the symptoms, Bosch customer service immediately said that I'd have to ship the unit back "for repair", so this obviously is a design flaw that they've known about for a long time and have failed to address. Now I'll be stuck with a $1,300 machine that required repair before its first use. I recommend that others steer clear of this product.

    I have been using a b60 for about 6 months. 2 days ago it made a huge "Whooosh" sound, the the "Fill UP PIPE-SYS" message appeared. I press "CAFE" and water comes out of the inside into the tray for 6 seconds then stops. The message "FILL UP PIPE-SYS" returns endlessly. Today i scheduled a tech to come repair it. They have no idea why it does this, but after close examination, it appears that either a seal has blown, or a sensor in the boiler has failed.

    Will try to remember to post a follow-up about this once/if resolved.

I have the exact same problem mentioned above with a brand new out of the box Bosch B30. The LCD screen says FILL UP PIPE-SYS / PRESS CAFE. Pressing the CAFE button causes the unit to say PIPE-SYS FILL UP. No noise is made. Then 10 seconds later it goes back to saying FILL UP PIPE-SYS / PRESS CAFE. This repeats forever. I tried calling Bosch customer support and they were clueless. The customer service lady went and asked "the their expert who works on these units" and all he says is "it's defective and shouldn't be doing that." My machine is definitely sensing water in the tank fine. If at anytime I remove the water tank or place an insufficient amount of water in the tank, the LCD screen gets stuck on ADD WATER until more water is added. After that, it goes right back to the FILL-SYS / PRESS CAFE loop.

SOURCE: Beans stick in hopper

The problem is that beans have particles and oil on/in them, jamming the switch which is giving you this message. Invert the unit on a hard surface covered with newspaper and give it a couple of strong taps against that surface. The junk should fall out and get you going again. Clearly, you're missing something when disassembling the unit.

Seems Problem with the bean sensor. you need to get the same replaced. there are no setting that can be done manually for bean sensor.

A Jura Engineer can check the Bean sensor with his computer system and confirm if the bean sensor is faulty.
