Impressa S8 problem - Jura Capresso Impressa S9 Coffee Maker/Espresso Machine

Put your finger on and take it off.

This error is because:
1- Flow meter is blocked & not sending signal of water flow.

2- Entire hydraulic system is filled with Calcium deposits and slowed down flow of water.
Solution:
1- Open the machine and manually clean flow meter. It is located between the water tank & the pump.
2- Follow this by manually descaling the machine. Seelink. Do not use automatic descaling method suggested by Jura.
Stop using Filter cartridges as the machine reminders for descaling are silenced by use of filters. Services Unlimited Inc Parts Guru Since 1988

You can check the water valve, it may become clogged. But you should not disassemble machine if you are not specialist. Contact Jura service center if your machine still under warranty.

Hi, I made a video how to fix your Jura step by step, good luck... http://fixandparts.wix.com/nicknicoloudis#!jura-coffee-machine/c15gy

I had the same problem and had success with cleaning the contacts in the back of the machine with a small nail file/emery board. I found that the contacts that are inside the machine had a little calisification on them. Once they were cleaned up no problem.

Look for answers here.

SENT IT TO FACTORY FOR REPAIR.

Most likely problem is over temp cut out switch. Small diode attached to the boiler to prevent damage during boil dry, or fault in the heating element itself. Difficult machines to repair and best handled by a service technician.

We have the S8 here at our office. Ran the cleaning cycle and "Clean Now" message was still on and beeping afterwards. Read the Feb 28 comment and carefully cleaned everything that had grounds stuck to it. Ran the cycle again and it worked. Thanks all.
