There’s no doubt that Jura coffee machines have now become an indispensable kitchen staple, without which we could become stuck in a sluggish world.

But just like your Jura machine gives you delectable cups of coffee, you too need to put in some effort to ensure its smooth functioning.

Since coffee is primarily composed of water (loaded with minerals like calcium, magnesium, and sulfites), you should consider regularly descaling your coffee maker to prevent any mineral buildup.

Today we will be reviewing Jura descaling tablets which are made for this sole purpose. Let’s get started!

Jura Descaling Tablets, 36 Pack

Your Jura coffee machines boiler is often left vulnerable to mineral scale buildup, which may affect your coffee in any of the following ways:

  • Mineral scale buildup may eventually lead to clogging. In some cases, the Jura machine may stop working altogether
  • The temperature of your coffee won’t be ideal for consumption

Jura has specially curated these 2 phase descaling tablets for their automatic coffee machines to overcome these problems.

They are made from a mixture of various organic and inorganic acids, which aid in the removal of calcium deposits and debris.

Aside from carrying out highly effective descaling, these descaling tablets also extend the service life of your coffee machine. They are square to facilitate an even dislocation in water and come in a color combination of blue and white.

They are easily soluble in water and contain extracts of sodium bicarbonate and maleic acid. Their dissolution time is roughly around 3-5 minutes, depending on the temperature of the water.

You can use them in other areas where you want to get rid of calcium deposits, such as kettles and boilers.

On top of this, Jura also offers a 30-day satisfaction guarantee and claims that only nine descaling tablets are enough for descaling Jura coffee machines up to 3 times.

Jura 66281 Decalcifying / Descaling Tablet (9 tablets)

This 9-pack of decalcifying tablets helps fight limescale. Even though calcium carbonate adds to the flavor of the coffee to some extent, an excess amount leads to an undesirable aftertaste in water. It doesn’t allow the coffee aromas to develop ultimately.

Limescale also narrows down the pipes of your coffee machines as it gets deposited on the inner walls prohibiting the heating process and increasing power consumption.

You should carry out the descaling operation in two phases:

  • Phase 1: Eject all of the scale residues out of the coffee machine.

While some individuals lean towards using citric acid for descaling, many have also reported that Oust works just fine and is a cheaper alternative.

You can also backflush by adding a fragment of a dishwasher tablet now and then. 

That said, the chance of wrecking Jura automatic coffee machines also increases as you start to use non-proprietary descales with it. 

Therefore, we advise you to always stick to the Jura descaling tablets as they were designed to work with Jura automatic machines. 


Can I use Jura cleaning tablets for descaling?

Can I use Jura cleaning tablets for descaling

No. The Jura cleaning tablets typically go in the brewing unit, whereas the descaling tablet is carried out by decalcifying tablets that come along with every Jura coffee machine. The cleaning tablets are also smaller in comparison and are used when the Jura machine shows an alert. 

The usual frequency varies from 2-3 months, depending on the user.

Both of these tablets have different functions and are aimed at cleaning other components. Cleaning is always to be carried out after using a descaling tablet.

The whole process significantly improves the coffee taste if done regularly.

How do you use Jura descaling tablets?

How do you use Jura descaling tablets

Take three descaling tablets and pour them in around 500ml of lukewarm water. While the beans dissolve, remove the filter from your coffee machine if it has one. 

Now tap on the maintenance button of your Jura coffee machine and navigate to ‘filter,’ and change the setting to ‘no.’ This will activate the decalcifying program. Make sure that your grounds are empty and there’s no water in the tank. 

Now start the program by adding your solution into the tank and press start. Place two jugs beneath the outlets and simply wait till the timer ticks off. The descaling process is now complete.

The recommended frequency is around once every month if you want your coffee machine to stay in a pristine condition. Another way to see this is by the volume of water used, i.e., 50 liters. 

Once your Jura machine hits this mark, you should conduct the descaling process to avoid scale residue buildup. If you happen to have an inbuilt filter, then you can go without descaling for 2-3 months.
