Question about Jura Capresso Impressa E8 Espresso/Coffee Maker
Checked tank water flowes from it just fine, float is moving fine, screen on E-8 inlet looks clear, water is flowing through the system very well. Have E-8 unplugged for 15 min to see if it will reset and it did not.
If it is the flow sensor that is not working one solution as mentioned above is to take the device apart and clean the flow sensor. However it is also possible to clean the flow sensor without taking the unit apart. (if you are a bit lucky):
Fill the water tank with HOT water with descaler (about 0,7 liter)
switch the unit on. the display will say: open tap, close tap, open tap close tap, etc. Do open and close it, as the hot water with descaler will pass through the system. Since the unit does not heat when the open tap close tap loop is entered you need the hot water to effectively dissolve the chalc. Collect the water with descaler from under the tap, and re-heat it in the microwave and put back into the water tank. Do this many times, as the hot water with descaler will slowly heat up the piping and flow sensor, and dissolve dust such as chalc. It took me 25 minutes of continuously opening and closing the tap and reheating of the descaler-water in the microwave. Then suddenly the flow sensor was clean enough and started to register waterflow again. The unit entered into Spooling (and heating) mode and was 'Ready'. Clean the unit and flush it a long time with fresh water. Now it is OK again.

The Open Tap/ Close tap loop is entered because the machine doesn't see any or not enough water flow when the pump is on. If you see that water is flowing out of the tap when open, then the flow sensor most likely is stuck. It's a round white plastic assembly with two water hoses an an electrical connection. It sits under the water tank and can be taken apart to clean it.. Make sure that the paddle wheel spins freely when blowing into the inlet after cleaning.See elsewhere on how to take the machine apart.

Open the tap with frother spout off. This happened to mine and I took the frother tip off and opened tap with tip off. Water filled and I closed tap...Machine returned "Ready". I heated water in microwave for three minutes- placed frother tip in hot water and all kinds of gunk came out. Lesson learned- Do a thorough cleaning of frother by immersing it in very hot water at least once monthly- even if you don't use it

SOURCE: My E-8 seems stuck
Check the water valve and water inlet nozzle.If the valve is not working or the nozzle is blocked then it will not let the water to run.Also see the water passing tube,if its blocked same problem can arise.:--- Disassemble the unit and check the internal parts:-- You will need about 4 different torx; hexagonal and possibly unique screwdriver bits to remove all screws. A plastic pry tool (used for mobile phones) will help where plastic lugs hold on the side and top panel. Empty beans; water store and remove the waste tray. You'll be able to remove the top panel after using a pry tool to disconnect two lugs at the front edge. Four screws hold the central back panel. Slide out a white key underneath the machine The side panels are removed by using a pry tool to release lugs all down the edge where these panels meet the front. Work slowly to take the side panels off. If you simply want to clean the brewing unit externally then just remove the panel on the water side. Find the water inlet just where the water tank sits. A screw here allows you to remove a plastic piece - but take a photo of how it slots in. This gives access to the lower end of the brewing unit. If the plastic piece is still it the way, you can ease off the water pipe from the water inlet and put it aside. You might just need to clear the inner chamber and path for two plungers with two large O-rings. You can see the water inlet nozzle with its o-ring which can perish and cause coffee or water to go to waste. The nylon water pipes - These pipes are held in place with a wire clip (remove with a flat head screwdriver). Ease the nylon pipe with its brass collar out of its socket. The pipe goes into an O-ring in the pipe's socket - this might fall out.The brewing unit is removed by undoing two obscure screws from the coffee grinder side. On the electronic side there's an optosensor (encoder) unit held in place with a steel clip. You might remove this to access one of the two screws. At the bottom of the brewing unit, the water inlet valve is fixed to the machine with a single screw. Next, on the water tank side, you'll see two lines of screws that hold the assembly in place. The middle screws of the screws allow you to separate the unit from the gears. The top two holes don't have screws. Now clean the water pipe,the water valve the nozzles.Also check O-rings the seal to O-rings.If there are loose,just apply car sealant to the side of seal.Then refit all parts and check. ----------------- For more help.Click this link directly to see disassembly instructions with pictures.Its not exactly same as your model,but its jura E series coffee maker only.So this will help.Click the link below:-- http://www.buessert.de/Technik/Jura-IMPRESSA-S95/Reinigungsanleitung.htm ---------------- This will help.Thanks.Helpmech.
