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!

Re: "water pipe empty" icon will not disappear from...

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.

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.

Leaks at the hot water spout during coffee brew

I had the same problem. I ended up taking the coffee machine apart and found that the reason coffee trickles out around the hot water spout is that the two coffee nozzles were partially plugged. Since I Had parts of the coffee machine apart I was able to clean it easily. It may also be possible to clean the assembly using a pick of some sort and clean out the holes of the two normal coffee spouts. Inside it is just a open cavity so gentle poking around and using some steaming hot water may do the trick.
If you want to take the machine apart you need to do the following: 1) take of the warmer plate on the top - 2 storz screws but an allen key works as well 2) take off the top plate of the machine - another 4 or 5 screws - make sure you empty the beans first otherwise you will have a mess 3) remove one screw from the right hand side of the removable coffee ground tray. Once this screw is removed the front panel is free to swing open except for the pipes connecting the front 4) unclip the steam assembly - there are a couple of plastic catches on the top. this will free the steam assembly from the front panel and also free a pipe connections. The steam dispenser pipe will also come free from the steam assembly. 5) remove the coffee pipes from the up and down sliding coffee dispenser. This is a small whitish color clip with 2 pipes connecting into it. The white clip has a little plastic catch on the top that frees it. The front panel should now swing open freely. 6) remove the sliding coffee dispenser from the front door. There are 4 plastic catches, 2 on either side. the whole front sliding coffee displenser now comes free 7) Take the sliding dispenser apart by release the 4 plastic catches on the front curved planel. 8) Inside the sliding dispenser is a white plastic piece that connected to the piping released in step 5. There is a small plastic catch that needs to be pressed while pulling fairly hard on the plastic piece and bending the whole piece. 9) You will now see the plugged spouts. It goes back together really easily.

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!
