Jura Espresso Machine How-to & Troubleshooting Guide

Jura Espresso Machine How-to & Troubleshooting Guide

Jura is a Swiss company that makes luxury coffee and espresso machines famous for their fully automatic systems and consistent brews. Jura engineers have made their coffee makers premium quality with a unique sleek design and easy-access touch screens to give you the best coffee-making experience. But, unfortunately, these automatic coffee machines are not without fault.

Like other coffee machines in the market, Juro coffee machines will present issues such as over-dilute coffee, failing grinders, coffee dispensing problems, frother issues, among others. This article will tackle some of the most common issues associated with the most popular Jura coffee maker models to help you troubleshoot them.

How do I reset my Jura coffee maker?

Resetting the Jura coffee maker will delete all previously saved settings, and all settings will go back to default. Follow the steps below to perform a hard reset.

  • Press “P” on the coffee machine screen.
  • Click the “machine setting” symbol.
  • Press and hold the “>” button until you see the “factory setting” option.
  • Click on “factory setting.”
  • A “reset the machine to factory setting” prompt message will appear on the screen, and click the “yes” option to confirm.
  • A “saved” message will appear on the screen to mean a successful hard reset.

Why is my Jura making watery coffee?

Most times, when the Jura coffee maker produces a weak or watery pour, the coffee grind could be too fine, or the water flow and grinder settings are wrong. Here are all the possible ways to fix your watery brew.

  • Check the grind setting and change it to a coarser grind. If you’re using ground coffee, make sure to use a coarse grind. Very finely ground coffee will block the system, making very little coffee to get to the brewing chamber. To avoid clogging your machine, you should use coffee beans. If you suspect your device is already blocked, you should unclog it before using it.
  • Low-quality coffee beans will produce very mild coffee even when brewed correctly. Make sure your coffee beans are well roasted and untreated.
  • Add more coffee to the machine will produce stronger coffee regardless of grind size or roast intensity; however, you should not add too much that it clogged the machine. When you use insufficient ground coffee, the Jura coffee maker will give a “Not enough ground coffee” alert on the screen.

How long should a Jura coffee machine last?

The average lifespan of a Jura coffee machine is about ten years. Though wear and tear will occur over time, they can last longer with proper use and maintenance. You can increase its lifespan by focusing on regular cleaning and descaling, mainly if you use the machine every day.

Jura coffee machine won’t turn on.

The most likely reason for a Jura coffee machine not turning on is either a burnt power switch or a blown-out fuse in the CPU board.

  • First, check to see if it has plugged into power and if it is, disconnect the coffee machine, plug it back in and press the power button.
  • If the machine still does not operate, ensure the power outlet is passing current. You can connect another appliance to the same power outlet to confirm if it is working. If it is not, check the circuit breaker for any tripped switches and reset them. If resetting does not work, look for burnt fuses in the power outlet. You should then replace any burnt fuses or the entire power outlet.
  • Check the coffee machine power cord and look for cuts or damages and replace it if necessary.
  • Check if the exterior power switch is damaged or stuck. A stuck or damaged button will not engage properly, therefore, preventing the machine from turning on. Unplug the machine and check for dirt between the button and the machine body. Use a toothbrush to remove dirt that may be causing the switch to get stuck. If the power switch has a short circuit, you need to replace it.
  • The thermal fuse in your coffee machine can engage and stop the flow of power if the machine becomes too hot. Check if the fuse has burnt out and replace it if necessary.

Jura empty drip tray error

If the “Empty drip tray” error does not clear after emptying the drip tray, the metal contacts on the drip tray are wet or dirty. Remove the drip tray, wipe the contacts to remove any stuck dirt and dry them thoroughly and then reinsert the drip tray into the machine.

Jura coffee machine; no coffee coming out

When there is no coffee coming out of the Jura coffee machine or dispensing coffee slowly, the system has clogged with fine ground coffee or limescale. Here is how to troubleshoot this problem and get your Jura coffee machine working.

  • Check the grind setting and adjust it to a coarser grind.
  • Check the water hardness setting and adjust accordingly. If the water hardness is s 10 °dH or more, you should use the Clearyl Blue filter cartridge that doesn’t require the descaling of your coffee machine. Use the Aquadue test strip to determine the water hardness level and then adjust it in our coffee machine settings.
  • Check the water filter in the coffee machine. If the filter has not been correctly installed or is clogged, it can limit water flow through the coffee grounds. Reseat the filter properly or replace it if you haven’t in a long time.
  • Check the coffee spout for clogging. The coffee residue will accumulate inside the coffee spout with use, especially if you do not rinse the machine after every use. Run a few cleaning cycles with the Jura cleaning tablets to clear out the obstruction. If the clogging is excessive, you need to clean the spout manually using a thin needle.

  • Power-cycle the coffee machine. Turn off the coffee machine, unplug it from power and allow it to cool off. After a few hours, plug it back in and try removing the coffee grounds container.
  • If that solution doesn’t work, then you should descale your coffee machine using three Jura descaling tablets.

  • Press the “<” or “>” buttons to adjust the switch-off time.
  • Tap “Save” to save the settings and then “L” to exit the programming mode.

How to descale a Jura coffee maker

Limescale mineral deposits from the water supply will accumulate in the coffee machine over time, and the device will automatically prompt you when it requires descaling. Descaling is the removal of hard water minerals.

  • Press the “P” button.
  • Click the “Start” button.
  • Press the “Next” button.
  • Pour out the drip tray and coffee grounds container contents and replace them in the coffee machine.

  • Once the tablets dissolve completely, insert the water reservoir with the solution into the coffee machine.
  • Place a mug under the foam frother and press the “Next” button.
  • Water will flow out from the frother while the machine is descaling.
  • The process will pause, and an “empty drip tray’ message will appear.
  • Remove the drip tray and coffee ground container, empty them and return them to the machine.
  • Remove the water reservoir, empty it and rinse it thoroughly to remove any residue.
  • Fill the water reservoir with clean cold water and reinsert it into the machine.
  • Place a mug under the coffee spout and another under the foam frother.
  • Press the “Next” button, and the clean water will rinse out the system.
  • Empty the drip tray and coffee ground container again, replace them, and complete the descaling process.
  • If the descaling process stops mid-operation, rinse the water tank thoroughly.

Can you use ground coffee in a Jura?

It is best to use roasted, untreated coffee beans in the bean container. Using finely ground coffee, instant coffee, or chocolate mix with the Jura coffee machines will damage the functioning of the brewing chamber. If you want to use pre-ground coffee, you should not use very fine coffee grounds, do not use more than two level measuring spoons of ground coffee, and they should go into the filler funnel instead of the bean container.

To prepare one cup of coffee using ground coffee;

  • Place a mug under the coffee spout.
  • Open the filler funnel cover for ground coffee, pour in one level measuring spoon of ground coffee into the filler funnel, and close the lid.
  • Press the “Espresso” button, and the coffee preparation will start and stop automatically when complete.
