Do I really need to descale my Tassimo machine?

All coffee machines will build up lime scale over time, which if left, will damage your Tassimo machine. Descaling regularly (depending on hardness of water) is required to prolong the life of your machine and importantly ensuring your drinks taste great every time!

You should aim to descale your machine every three months (max) but as mentioned above, it will depend on your water hardness, if you have hard water you will need to do this more often.  The great thing about your Tassimo machine is that it likes you and wants you to clean it so it tells you when it needs descaling when the red descale light comes on, so no guess work required on your part.  Helpful!

What is Limescale and Where does it come from?

Limescale is a layer of crystallized lime on the top of many surfaces. It usually comes from water when it is heated and the lime left in the water sits on the surface.

Usually seen in the boiling containers and hot-water pipes of heating systems, limescale can be a difficult problem to deal with.

Hard or soft water

Lime usually is formed through two kinds of waters and has different contents.

Hard water soft water limescaleSoft water limescale, usually formed in kettles, coffee makers and hot water boilers, is the one that contains calcium carbonate. It is formed when the water in the boiling container heats and precipitates the compound. When the water is heated, the whole processes cause the water to become hard temporarily. This causes the elements in the water to become insoluble and will settle down at the bottom of heating containers such as heating systems, cylinders and kettles.

The other type of limescale is formed when the water is hard. This kind of water usually runs in pipes and heating systems. So, the limescale, consisting of calcium, magnesium and other carbonates is found in the inner surface of pipes. This will cause the evaporated water to form limescale deposits both in the pipes and heating elements of your Tassimo coffee machine.  Which in turn make the heating of water more inefficient and also lead to valves, filters and pipes becoming clogged, which essentially stops your coffee machine from brewing your drinks.

Calcium carbonate limescale is found in hot water as it is not soluble in cold water. Other limescales are usually formed in cold water and are soluble.

How to remove limescale

There are two simple methods to deal with all the limescale deposits.

Method 1

As prevention is always better than cure, limescale deposits are easier to stop from forming, rather than trying to remove them. The easiest method is to make the water soft, so as to prevent it from forming limescale deposits in the first place. To make the water soft, ion exchangers are used which replace the calcium ions that are the cause of the deposits and form sodium ions. This way the water becomes soft but the whole process is expensive and has the tendency to cause corrosion in the fittings.

Method 2

The second method is to remove the deposits that have already been formed and are causing the appliances to work inefficiently, this is essentially what we do when we descale our Tassimo coffee machines with descaling tablets or other descaling solutions.

Home Remedies for Removing Limescale

For the removal, there are many techniques available. There are simple home remedies that have the acidic effect and work on the deposits to remove them.

Acid Cleaning

These include vinegar and lemon. The acids need to remain in contact with the deposits for some time to clean them from the surface.

Abrasive Cleaning

Other than acids, scrapers and abrasive can also be used to physically remove the deposits by rubbing them from the surface. However, with this kind of metals and abrasives, there’s always the danger of scratching and damaging the surface, so we absolutely would not recommend doing that!

Commercial Products

There are commercial products available in the market, which contain chemicals, that can easily and efficiently remove limescale deposits and will work well on the surface without damaging it.

bosch tassimo descaling tabletsThe two main ways to descale your coffee machine is to either use household items to remove the various forms of limescale or you can always try the commercial products available in the stores. In house remedies, which include lemon juice and vinegar, are both effective for removing the limescale deposits. The acidic nature of these items can be quite effective and easy to use.

However, it’s not the acid availability usually but the problem of keep it soaked with the deposits to remove them. So, in that case commercial products may be more effective when it comes to stubborn deposits.

  1. Firstly unplug your machine from the electric socket.
  2. The water tank can be removed.  This is either located at the back or side of your Tassimo.
  3. Filter assembly.  There should be a filter assembly attached to the water tank which can also be removed for cleaning.

  5. Brew head.  The brew head can be removed by pulling carefully to lift and unhook the clips at the back of the brew head.  The brew head should then lift out ready for cleaning.

There are many products available in stores that can easily remove all kinds of limescale problems, without damaging the components of your coffee machine. But, given how cheap tassimo descaling tablets are, we would recommend simply buying these from your local store or online, and descaling your Tassimo machine regularly.
