Troubleshooting guide for Krups coffee makers

The Krups brand is known worldwide and is one of the most prestigious in the coffee maker sector, which has been manufactured for more than 40 years. Mainly we can find Krups pod, super-automatic, drip, and espresso coffee makers.

If you have arrived here looking for a solution to a problem with your capsule coffee maker, visit the guide that corresponds to your type of coffee maker, but if you want to know all the problems and solutions of your Krups over the rest of the coffee makers, read on.

Useful information on Krups coffee makers breakdowns

I remind you that if your Krups coffee machine is new, and it is less than 30 days since you bought it, you can contact the seller and request an exchange or a refund. For this you will need the purchase receipt.

If the first 30 days have passed, if your Krups is less than two years old, you can still make a claim to the manufacturer through the guarantee terms and conditions (different for the United States).

Here are the main contact details for Krups worldwide:

Troubleshooting for Krups superautomatic coffee makers

Krups superautomatic coffee makers, also known as Bean to Cup, are a benchmark in this type of coffee maker. All Krups superautomatic models are high-quality coffee makers for their materials, efficiency, and technology. However, despite this, they can also present faults from time to time.

One of the weak points of Krups superautomatic coffee makers is related to cleaning, which despite being very precise machines, coffee residues will eventually cause failures. This is why regular cleaning and descaling are so important in this coffee maker.

Problem with the “cleaning” light of a Krups coffee maker

When the “cleaning” button of a Krups super-automatic coffee maker starts to blink, it is synonymous that the coffee maker needs a cleaning cycle. The problem arises when, after cleaning, the button continues to blink.

The first thing to do is to perform another cleaning following the instruction manual of your coffee maker to the letter. If you do not like to read or cannot understand the steps well, visit my article on how to clean and descale a Krups super automatic.

Fortunately, Krups coffee makers allow us to continue using the coffee maker even though this annoying light is always blinking.

Most likely, the coffee maker has not been able to store the last cleaning in its memory, which is why it is requesting it. Be sure to run a new cleaning cycle, and do not interrupt the process at any time. You can also perform a descaling and see if the blinking light disappears.

In this video, we see an explanation of how to perform the cleaning process correctly in a Krups EA8081:

Note: If, after performing multiple cleaning/descaling cycles and cleaning the machine inside and out, the light is still blinking, there may be a problem with the control board. This can only be solved by purchasing a new one.

Problems with the grinder of a Krups coffee maker

In theory, the interaction that a user of a Krups super-automatic coffee maker has with the grinder consists of adjusting the degree of grinding through the knob located inside the hopper.

If all goes well with your Krups, this should be enough to modify the grind’s thickness and adapt it to the different coffee beans you use or the beverages you prepare.

However, this is not always so simple, and a common problem encountered by many users is that the grinding time is too long, preventing them from preparing quality coffees. The grinder should take between 6 and 8 seconds during grinding; anything longer than this time will not give good results.

To modify this grinding time, we have to access the service menu of the machine, and as it is not an easy task, I have prepared an exclusive article to modify the grinder’s time to grind the coffee beans.

Krups super-automatic, all lights flashing

One of the worst situations with a Krups super automatic is when all the lights (or some of them) start blinking for no apparent reason. In most cases, the coffee maker will be blocked and will not allow us to perform any operation.

It does not matter how often you take out and put it in the grounds container, water tank, or drip tray. The lights keep blinking despite checking everything or turning the machine on and off.

If you have checked all the sensors and the Krups are clean, there is a problem with the control board. And the problems related to these boards usually have no solution, so I suggest two things:

  1. Perform a reset within the service menu of the coffee maker.
  2. Replace the control board. This should not cost you more than $30.

The Krups coffee maker leaks water

As we said in the introduction to this article, Krups manufactures coffee makers for Nespresso and Dolce Gusto but also has a line of super-automatic coffee makers. Therefore in this section, we will deal with the water loss of the super-automatic machines, and we leave you the links for the capsule coffee machines here:

Water leakage through the coffee brewing unit piston

The most common place where a Krups super-automatic coffee maker loses water is through the piston of the brew unit (water with coffee) since this is a moving part continuously surrounded by coffee and water at high temperatures.

In the following image, we can see where it is located in a Krups EA model. To get to it we are going to disassemble only the upper part of the housing of the coffee maker, for which you will need a Torx 15 screwdriver.

Once you access the piston, you have two options; on the one hand, you can disassemble it and clean it well, or on the other hand, you can replace it with a new one that will cost you only 10 Euros. In the following image, you can see the difference between an old one and a new one:

Water loss through the flow meter or pipes

The second most common point through which a Krups super-automatic coffee maker can lose water is through pipes through which the water circulates inside the machine or through the flow meter.

All these components are subject to a lot of stress due to the continuous circulation of water, added to the coffee maker’s vibrations while it grinds and prepares the coffee. The pipes can often come loose, or the flow meter can open. To delimit the problem, you should disassemble the right side of your coffee maker and observe where the water drips:

Water leakage from the thermoblock or pump

Two of the most important elements of the Krups super automatic could be damaged; we are talking about the thermoblock and the pump. Both elements are in continuous contact with water and, therefore, susceptible to leakage.

The thermoblock can sometimes crack, so we would see clean, hot water dripping from the base of the coffee maker. If the water pump has a damaged internal O-ring, we would see water in the base of the coffee maker, but this would be cold.

You must almost disassemble your Krups super-automatic coffee maker to locate this type of leak. Once the casings are removed, prepare a coffee and see if the culprits are the pump or the water heater. If these components are the culprits, it is best to replace them.
