quick tips

  • Clean the milk system every day

    The ENA 8 uses Jura's HP1 fine foam milk system. Clean the milk system daily after preparing milk drinks to maintain hygiene and consistently smooth milk foam.

  • Replace the milk hose regularly

    Jura recommends replacing the milk pipe approximately every three months. A worn hose can reduce milk flow, introduce air leaks and affect foam quality.

  • Use a CLARIS Smart or Smart Mini filter

    The ENA 8 automatically detects genuine RFID-enabled CLARIS Smart filters. Using one reduces limescale build-up and means the machine will only request filter replacement rather than regular descaling.

  • Adjust the grinder only while grinding

    If you need to change the grind setting, always do so while the grinder is operating. Adjusting it while stationary can damage the grinder mechanism.

  • Run the cleaning programme when prompted

    The ENA 8 will request a cleaning cycle after approximately 160 coffee preparations or 80 switch-on rinses. Complete the programme using genuine Jura cleaning tablets to protect the brewing unit.

  • Empty the coffee grounds container while the machine is switched on

    The ENA 8 only resets the coffee grounds counter when the container is emptied with the machine powered on. Emptying it while switched off may cause repeated "Empty grounds container" messages.

FAQ's

  • Why is my Jura ENA 8 producing poor milk foam?

    Poor milk foam is usually caused by dried milk inside the HP1 frother or worn milk tubing. Run the automatic milk cleaning programme, dismantle and rinse the frother, and replace the milk hose if necessary.

  • Why does coffee only drip slowly from my Jura ENA 8?

    Slow coffee flow is commonly caused by an excessively fine grinder setting or limescale restricting water flow. Adjust the grinder one or two settings coarser and descale the machine if you are not using a CLARIS Smart filter.

  • Does the Jura ENA 8 need descaling when using a CLARIS Smart filter?

    Normally no. When a genuine CLARIS Smart or Smart Mini filter is installed and activated, the ENA 8 manages water quality through filtration and will instead prompt you to replace the filter when required.
