Attention Jura Automatic Coffee Machine Owners
  • When making a cup of coffee, espresso or cappuccino, does your Jura machine seem to run longer than normal?
  • When making a cup of coffee, espresso or cappuccino, does the water pump sound really loud?
  • Does your Coffee creme taste weak?
  • Do you get a "Fill System" error, when your water tank is full?
  • After making a cup of coffee, espresso or cappuccino, do you notice a puddle of water at the bottom of your Jura machine, or puddle of water on your countertop? 
Well... It sounds like your Membrane Pressure Regulator is faulty or worn out.

No worries, with a new Membrane Pressure Regulator you will regain your delicious cup of Jura Coffee Creme!

The membrane pressure regulator regulates the water pressure flow within the Jura machines.  Without this pressure regulator, the pump will be a lot noisier and will not regulate the required operating pressure.   In addition, this part leaks frequently and therefore is the most frequently replaced mechanical component in Jura machines.

This membrane regulator connects/screws to the Invensys ARS CP3 110V water pump, then connects to the hair pin lock connection to the high pressure Teflon/PTFE tube.

The membrane regulator comes with the following:

  • One OEM membrane pressure regulator
  • One O-ring for pump outlet connection (Larger O-ring, Black)
  • One O-ring for PTFE tube hairpin lock connection (Smaller O-ring, Red)
  • Note: Lubricate the O-rings before installation using only the NSF approved food grade lube for smooth insertion and proper sealing to avoid any leakage.
