Last Updated on September 23, 2023 by Timothy Byron Smith

There is no doubt that Jura coffee machines are wonderful and reliable products. However, even the most rigorously thought-out designs can have flaws, that is why your Jura is probably troubling you a bit. But don’t worry, some Jura coffee machines common problems can be easily solved.

Here are all the common issues (and their solutions) that might arise for Jura coffee machine users. We are sure you’ll find the problem troubling you here too and you’ll be able to fix it in a jiffy!

Jura Coffee Machines Common Problems

Jura is a swiss coffee machine brand that has thrived since its launch in 1931. It has quickly become a fan favorite and many coffee lovers have a trusting bond with Jura coffee machines. However, some users have also struggled a little with some technical problems.

Let’s find out the problem preventing your Jura coffee maker from brewing magic so you can fix it and get your dose of caffeine ASAP!

Coffee Losing Heat

Although Jura coffee makers are designed to brew the ideal cup of coffee at optimal temperature, there are often complaints about the coffee not being hot enough. Of course, if your favorite beverage isn’t hot enough how can you ever enjoy it?

Firstly, this isn’t necessarily a defect in your coffee machine. Automatic espresso machines are programmed to regulate the temperature to burn the coffee. So, while the beverage is optimal, it is not as hot as when poured directly from the kettle. But that doesn’t mean you give up!

There are a few hacks you can try to get your caffeine beverage burning hot just as you like it.


  • Increase the delivery time of the milk froth. Plus, pinching the milk tube a little as the milk froth is flowing from it can also help.
  • Preheating your cup/mug can also make a big difference to your coffee temperature. If your coffee machine doesn’t have a heating tray, add boiling water to the cup. Throw the water and immediately place it on the drip tray to fill with coffee.

Jura Machine isn’t Frothing Properly

Frothing issues can really put a damper on your mood for a specialty coffee. Most frequently this problem occurs due to an unclean milk system. So, the first step is to perform a thorough cleaning routine.

If the problem persists it can be because of a few other reasons. For instance, bad quality of milk, the inconsistent flow of milk, or a crooked pipe.


  • Thoroughly clean the milk pipe.
  • Froth again using a different kind of milk.
  • Examine the milk pipe for dents or damages. If the pipe is badly damaged, replace it with a better one.
  • Thoroughly clean the steam wand.

Grinder Malfunctioning

Suddenly, your coffee grinder isn’t properly dispensing coffee grounds. This can be a very frustrating time especially when you’re in a dire need of caffeine.

Before jumping to the worst conclusion that your grinder is gone for good, there are other fix-able issues you can ponder. A malfunctioning grinder can be the result of clogging. Coffee residues frequently accumulate in the grinder’s upper and lower burrs. Clogging it and reducing its performance.


  • Thoroughly clean the grinder.
  • Reduce your usage of oily coffee beans in the grinder.
  • Replacing the grinder blades can do wonders.

Jura Coffee Machine Common Water Reservoir Issues

In this section, we’ll delve into common water tank errors and how to address them effectively.

1. Water Leaking from Water Tank

One of the most frustrating issues you might face with your Jura coffee machine is water leaking from the tank. This problem not only creates a mess but also affects the overall functionality of your machine. Let’s explore the causes and solutions for this issue.


  • A cracked water reservoir.
  • Defective O-rings.
  • Damaged or leaking steam wand.


  • Examine the water tank for visible signs of leakage.
  • Fill the water tank completely with water and observe if it starts dripping or flowing from its surface.
  • Clean any limescale buildup from the joint and pipes at the bottom of the machine.
  • Disassemble the steam wand stopper and check for any components that might be leaking.
  • Descaling the steam wand can often help resolve leakage issues.
  • If possible, replace any damaged O-rings for a more secure seal.

2. Fill Water Tank Message

Another water-related error message you might encounter is the “Fill Water Tank” message. While this message is usually a prompt to add water, it can sometimes appear erroneously. Let’s understand why this happens and what you can do about it.


  • The magnetic float inside the water tank may get stuck due to sediment buildup, preventing it from making proper contact with the internal water level sensor.
  • In some newer Jura models, this error can occur due to a malfunction in the Water Level CPU.


  • Unplug the power cord from the socket and securely plug it back in, ensuring it’s properly seated.
  • On your Jura machine, press the filter option and switch from “yes” to “no.” This substitution should replace the filter option with a descaling one on the maintenance menu.
  • Press the descaling option, and your machine should automatically initiate the descaling process.

If these steps don’t work, consider powering down your machine and restarting it after a brief interval. This often restores the descaling option on your machine.

3. Water Filter Not Tight

A loose water filter may not seem like a significant issue, but it can lead to problems in your Jura coffee machine’s water circuit. Understanding why this occurs and how to ensure a tight water filter is crucial.


  • Air may enter the water circuit, potentially damaging components, especially the Water Pump.


  • Inspect the Water Filter Bracket to ensure it’s not broken and can securely hold the water filter.
  • Check the bottom of the water tank where the water filter is inserted for any signs of damage.
  • If the water filter isn’t properly secured, take steps to tighten it, ensuring no air can enter the water circuit.

Coffee Tasting Weak/Bitter

What makes a bad day worse? Bad coffee. A bad-tasting coffee is not always because of a bad batch of coffee beans or a cheap coffee brand. Sometimes it can be the doing of your coffee machine.

If your Jura coffee machine is brewing bad or weak coffee it is likely due to over-extraction or poor maintenance of the machine.


  • Change grinding settings. Switch them to the ‘coarse grind’ option.
  • Change the water filter.
  • Clean your water reservoir and fill it with filtered water.
  • Thoroughly clean the milk system.
  • Decrease the Jura coffee machine brewing time.
  • Descale the coffee machine.
  • Balance your coffee to water ratio.

Jura Error in the Descaling Option

Descaling is the most important feature of not just the Jura machines but any other coffee machine too. Although descaling isn’t done every day, it is important to be done as frequently as possible.

You just need a little bit of know-how and explore your machine a little to figure out the descaling procedure and options. The most common cause of the descale option not working or showing is a power supply failure.


  • Unplug the power cord from the socket and carefully plug it back. Make sure it is properly secured in place.
  • Press the filter option on your Jura and scroll from yes to no. This will substitute the filter option for a descaling one on the maintenance menu.
  • Press down the descaling option. Your machine will automatically start the descaling process.
  • If this doesn’t work then power down your machine and power it back up after a while. This will restore the descaling option on your machine.

Jura Coffee Machines Common Coffee Dispensing Errors

In this section, we’ll delve into common coffee dispensing errors and provide insights into diagnosing and resolving them.

1. Coffee Dispensing Slowly

If your Jura coffee machine is dispensing your beloved brew at a snail’s pace, it can be quite frustrating. Slow coffee dispensing can have several underlying causes that need to be addressed.


  • The grinder is set to grind coffee beans too finely, leading to blockages within the machine.
  • Water hardness settings may not be optimized, affecting the flow of water through the coffee grounds.


  • Adjust the grinder settings to a coarser grind. Ensure you vacuum out the grinder before making this adjustment.
  • Manage the water hardness settings on your machine to ensure an optimal flow.

2. Coffee Dispensing Unevenly

Uneven coffee dispensing can ruin the perfection of your cup. When coffee pours inconsistently, it’s essential to understand the potential reasons behind this issue and how to rectify it.


  • Partial clogging of coffee dispensing spouts can lead to uneven flow.


  • Run a cleaning cycle to temporarily address the issue. However, manual cleaning of the spouts may be necessary for a more permanent solution.

3. Coffee Leaking Behind Spout

Finding coffee leaking behind the spout is not an ideal situation. Understanding why this happens and taking the right steps can help mitigate this problem.


  • Incorrect water hardness settings can result in water bypassing the coffee grounds and leaking behind the spout.
  • The water filter may not be properly installed or may require replacement.


  • Check and adjust the water hardness settings on your machine to ensure proper water flow through the coffee grounds.
  • Inspect the water filter’s installation and consider replacing it if it’s old or damaged.

Jura Coffee Machine Not Producing Crema

Crema is the beautiful golden crown on top of your coffee that traps all the aromas and intensity of the coffee. If you’re noticing that your Jura machine isn’t producing as good a crema as it used to, it’s time to make some adjustments.

One and the most likely problem could be with your coffee beans.


  • Reconsider the kind of coffee beans you are using. Flavored coffee beans or dark roast beans produce more oils that clog the machine.
  • Unclog and clean the machine to remove obstructions.

Common Drip Tray Error Messages

In this section, we will explore some of the common error messages related to the drip tray and provide guidance on resolving them.

1. Empty Tray

One of the frustrating messages you may encounter with your Jura coffee machine is the “Empty Tray” warning. This error message is your machine’s way of letting you know that it’s time to attend to the drip tray. But why does it appear, and how can you troubleshoot it?


  • The drip tray has reached its maximum capacity, and the water level has risen to the point where it’s contacting internal metal contacts.
  • Accumulated wet coffee grounds in the vicinity of the metal contacts can lead to a false reading.


  • Before considering part replacement, try gently removing the metal contacts from the drip tray. Clean both the contacts and the drip tray where they connect with soap and water.
  • Inspect the internal contacts within the machine, and clean them with a slightly moistened cotton swab using a mild cleaning agent for metal.
  • If contacts are dulled or corroded, they may need replacement.

2. Tray Missing

Another error message you might encounter is “Tray Missing.” This message indicates that the machine doesn’t detect the presence of the drip tray. It’s essential to understand why this message occurs and how to troubleshoot it.


  • The drip tray has not been inserted correctly or is not making proper contact with the machine’s sensors.


  • Ensure that the drip tray is correctly placed within the machine, making secure contact with the sensors.
    If the problem persists, inspect the machine’s sensors and ensure they are functioning correctly.
  • In some cases, the machine may have a micro-switch activated by the drip tray or grounds container tray. If this lever is broken, jammed, or corroded, it can lead to the “Tray Missing” message. Replacement of the micro-switch may be necessary.

3. Drawer Missing

When your Jura coffee machine displays a “Drawer Missing” message, it signals an issue related to the coffee grounds drawer. Understanding the implications of this message and how to tackle it is crucial.


The machine doesn’t recognize the presence of the coffee grounds drawer, hindering the brewing process.


  • First, ensure that the coffee grounds drawer is properly inserted.
  • If the message persists, examine the coffee grounds drawer for any signs of damage, particularly on the rear tabs.
  • In some cases, the tabs on the coffee grounds container tray may be broken, causing the machine to register an “Empty Grounds” message even when the container is empty. Replacement of the coffee grounds container tray may be required.

These insights into common drip tray error messages and their troubleshooting should help you address these issues effectively, ensuring your Jura coffee machine continues to brew your favorite beverages seamlessly.
