How do I remove the algae that is inside the floating magnet box within the water tank? It gets stuck and keeps telling me to "fill the water tank"

SOURCE: Float in the water reservoir

I poured vinegar in the reservoir and it dislodged the float. I then was able to fill the system by pushing the steam button. THen I ran the vinegar through the system. Saved me $220. Yippie!

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.
