Question about Bosch Benvenuto B20 Espresso & Coffee Maker

"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.

Cant start the coffee

VPS/VPR (VP17-3 are the same except it has 3 lower warmers) are pour over brewers. Like the 12 cup brewers you find at home, they need to be filled with 12 cups of water (a full pot), heated and then peculated over the coffee grounds and collected in a decanter.
BUT there is one main difference! The VPR and similar COMMERCIAL coffee machines are quick brewers. They usually have a pre-heated pot of water stored inside the machine.
* VPR's and similar machines REQUIRE a pre-fill and heating period prior to brewing. This means it's sitting on a level table and filled with water until water sprays from the brew head. At this point the unit is plugged in and the heater is turned on (there may be some water discharge from brew head as the water expands). Ready light will come on in about 15 mins.
* To Brew; Place coffee grounds in filter, place in funnel and brew head, clean empty decanter under funnel, slowly pour one full decanter of water (cold or hot) into brew tray. Do not overflow tray. Allow water level to sink before adding more water. Only fill with one pot as an equal amount will come out the brew head and funnel.
* Make sure the decanters are all the same size. do not mix a 12 cup pot with a 10 cup pot. One will over fill and the other will under fill. Make sure they match (in cup volume) FYI; Thermo Air pump pots are usually bigger than one pot. Typical filling only to 3/4th of the container. (I think most are in 2.5 to 3 liter sizes)
* If your not getting a full pot then the brewer was partially empty. The second brew (if done within the next hour) should come out full.
* If your still not getting a full pot then the water is leaking or is boiling off. Does it always steam from the top? Thermostat is shorted. Unplug the brewer and call vendor for service.
* Final; If your unplugging when not in use. Then follow the Pre-heat instructions mentioned above prior to plugging the brewer back in. If the tank has been emptied at night or dried up after an idle week. Then there is a chance you may over heat and blow the thermal fuse. Or at best have a half pot short brew as the water dried up.
* Note leaving the brewer plugged in without brewing daily is not a good idea. The water evaporates and eventually drys out the pot. Takes about 1-2 weeks but it does blow the fuse(s) and the unit will need service.
* Final; Follow the Bunn set up and care instructions (manuals from for down loading. *FREE*)

Doesn't always brew all the water, stops early

All coffee makers do this over time from calcium, lime, and mineral deposits building up inside the tubes and heating coil. Fill the reservoir with a 50/50 mixture of water and white vinegar and run a normal brew cycle, turning it off and on if necessary to completely empty the reservoir. Repeat this 2 or 3 times with fresh mixture of vinegar and water until it brews the reservoir empty without the need to cycle the power. Follow this procedure with plain water 2 or 3 times to clean the vinegar out. This should get it working like new again. It's best to use distilled water for brewing coffee as distilled water does not have the minerals that regular tap water has and therefore will not clog up the machine.

Keurig B60 is real slow , displays brewing for 30 sec.

mcdevito75 here, It may need to be cleaned, water used to brew coffee leaves deposits in the brewing holes and must be cleaned every once in a while. Refer to the owners manual on cleaning the coffee maker.

Our Rancilio Silvia is producing really bad tasting coffee of husband thinks that it is old water but I think it may have something to do with the fact that it has been leaking from the steam...

More than likely its you brew head screen. Coffee will build up on the top surface and turn rancid after awhile. Remove the screen(its either a screw or bolt that holds it on). I like to remove everything and turn the machine upside down on a towel. That way I can see what I am doing. Clean everything even around the brew head gasket. This gasket needs to changed every year for best sealing of the portafilter. Buy 2 because they always fail on Friday when you have a party on Saturday.
Soak you brew head screen in hot water with a pinch of automatic dish washing detergent or espresso machine cleaner. Use a tooth brush to remove the crusty burnt on coffee residue or just buy a new screen. Clean this screen every 6 months because they should last the life of the machine.

Reads decalcify, brew unit missing- and wont make coffee!

Open you door on the right. Push on the upper left side of your brew unit and see if it will click. You have to push fairly hard towards the center of the machine. If it clicks the outlet pipe needs to be lubricated. The outlet pipe is the angled pipe on the top left side of the brew unit in the back. Lube the end of the pipe with food grade not food based lube.

Cuisinart grind and brew

This happens when the machine needs cleaned. Fill coffee maker with white vineger instead of water. Turn grind off, make sure empty pot is in place. Brew a pot of hot vineger. Repeat. Brew a pot of hot water. Repeat. This process removes mineral buildups inside machine. If you have access to filtered water, start using that to brew your coffee. I do and probably do this process 1 per 6 weeks.

3-Pot coffee Maker instructions

The first time you use the machine you need to make sure it is full of water - before you plug it in and turn it on. Put an empty coffee pot under the brew basket and fill another empty pot with clean cold water.

Pour the water into the coffee maker. If water comes out then you can plug it in and turn it on. The water heating tank holds about 2-1/2 pots of water so if your machine is empty you will need to keep adding water before you turn it on otherwise you may burn up the heating element.

After the green light comes on - indicating that the tank is hot you can brew a pot of coffee. This machine is meant to be left on all of the time so it is always ready to brew. If you choose to turn it off when not in use, you will need to give it about 10 minutes to fully heat up the water before you brew.

Trying to ventilate and hot water not flushing through on button 26

Before you press water button to vent you need to restore to factory settings.

First press menu (far right button) then toggle to restore factory settings (using far left button), press menu button then far right again until yes comes up, then press menu button. Press esc button (3rd from left), machine should now be back to normal. Then press water button (3rd from right) and turn steam knob to vent until free water is coming through.

This is the only way I could get mine to work!
