Dealing with dirt in Krups coffee machines
Let me begin by informing you that in this guide, I will show you how to repair and maintain your Krups superautomatic coffee maker by YOURSELF.
One of the vulnerabilities of Krups superautomatic coffee makers is related to cleanliness. Despite their precision engineering, coffee residue can gradually lead to malfunctions. Therefore, it is crucial to perform periodic cleaning and descaling to ensure the optimal performance of these coffee makers.
➡️ Check out this article about cleaning and descaling Krups superautomatic coffee machines.
Problem with the “clean” light of a Krups coffee maker
When the “clean” light of a Krups super-automatic coffee maker starts to flash, it is synonymous with needing a cleaning cycle. The problem arises when, after cleaning, the button continues to flash.
The first thing to do is to perform another cleaning following the instruction manual of your coffee maker to the letter. If you dislike reading or cannot understand the steps well, visit my article on cleaning and descaling a Krups super automatic.
Fortunately, Krups coffee makers allow us to continue using the coffee maker even though this annoying light is always flashing. Most likely, the coffee maker has been unable to store the last cleaning in its memory, so it is requesting it. Be sure to run a new cleaning cycle, and do not interrupt the process at any time.
⚠️ Note: If the cleaning light keeps flashing even after you’ve run multiple cleaning cycles, it could indicate a problem with one of the sensors (such as the water tank, drip tray, or coffee grounds drawer) or, in the worst-case scenario, a malfunction in the control board. You can try to reset the machine or purchase a new control board.
Problems with the grinder of a Krups coffee maker
It’s essential to regularly clean the grinder, especially if you use oily beans. Over time, oils and coffee grounds can build up on the burrs, creating a layer that hinders the grinder’s performance. This might lead you to believe the grinder is malfunctioning when, in fact, it just needs a good cleaning.
➡️ I’ve covered how to do this in another article on grinder issues. click here.
In theory, adjusting the grind level using the knob inside the hopper should be the only interaction necessary for Krups super-automatic coffee maker users. This allows you to customize the grind thickness to suit different coffee beans and beverage preferences.
However, some users encounter an issue where the grinding process takes too long, resulting in a less-than-optimal coffee experience. Ideally, the grinder should complete the task in 6 to 8 seconds for the best results.
We must access the machine’s service menu to modify this grinding time. As it is difficult, I have prepared an exclusive article to modify the grinder’s time to grind the coffee beans. Also, I included a manual calibration for the Krups EA81 series.
Krups super-automatic, all lights flashing
When all the lights on your Krups coffee maker appear to turn on without any apparent reason, it’s important to ensure you are correct in your assessment. In other words, you need to decode the meaning of the pattern they follow when illuminating. I have created a comprehensive guide for you to assist you with this. Click here to view it.
The illumination of the buttons for no apparent reason on a Krups coffee maker can be indicative of two different types of situations:
- First, we have what we might call a “malfunction.” This refers to when the button lights signal actions such as cleaning or the need to add water but remain on even after the required action has been completed.
This usually happens when a sensor in the brewer does not properly recognize the action performed. For example, if the coffee maker asks you to insert the waste coffee drawer, but it does not fit properly, or if the detection sensor is dirty or damaged, the button lights may remain on.
To solve this problem, there is no other solution than to disassemble the coffee maker and check if a microswitch (grounds drawer/drip tray, among others) or a sensor (flow meter/water tank sensor, among others) is working properly.
➡️ To learn how to evaluate the state of the microswitch, here is a useful video guide:
- Secondly, there is what we might call a “failure.” This occurs when all the button lights flash simultaneously, or the Krups suddenly shuts off.
These situations are more serious and usually indicate a problem that could endanger the user’s safety or the coffee maker’s integrity. These faults are usually related to critical components such as the thermoblock and thermostat. If the temperature rises too high or the coffee maker cannot read it correctly, the machine automatically shuts off for safety reasons.
In this case, it is not advisable to attempt a standard reset, as it is necessary to consider replacing the thermoblock or thermostat (NTC) to solve the failure.
➡️ In this other video, you can see how to fix the NTC sensor contacts:
➡️ 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:
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 coffee pod 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 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 will 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: 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 $15.
The following image shows how the piston is disassembled, and each part is cleaned and reassembled as it was. Pay special attention to the black rubber valve:
If water escapes through the piston, it is either because the O-rings are not sealing properly and, therefore, you should buy new ones (see the purchase link) or because the black rubber valve is clogged and causes the pressure to increase too much in the coffee brewing chamber.
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 via the pipes that circulate water inside the machine or through the flow meter.
All these components are subjected to significant stress due to the continuous circulation of water, combined with the vibrations generated by the coffee maker during the grinding and coffee preparation process. The pipes can often become loose, or the flow meter may open.
To identify the problem, you should disassemble the right side of your coffee maker and observe where the water is dripping:
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 that 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 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.
