Why Is My Krups Coffee Machine Leaking – A Step-By-Step Troubleshooting Guide

A coffee machine is an excellent choice for brewing a mug of your favorite coffee for that stimulant kick every morning. However, repeated use, accidents, or sheer bad luck may damage your Krups coffee machine, causing a leak at the bottom.

If the capsule holder is dripping and pools of water materialize under the machine after every use, your machine is probably damaged. The financially stable often solves the problem by replacing the dysfunctional Krups coffee brewer with a new one. However, most issues, including leaking at the bottom, can be easily fixed without breaking the bank if you know how to go about it.

In this article, we are going to list a step-by-step guide on how to troubleshoot a leaking Krups coffee machine and offer some tips on how to fix the problem. Tag along.

Troubleshooting a Leaking Krups Coffee Making Machine

The main indicator of a leaking coffee brewer is water loss that ends up at the bottom. Immediately after use, lift the machine and inspect the surface below. You will see droplets or the formation of pools of water on the countertop below. The water loss may be pronounced or diminished depending on the severity of the issue.

If the first method doesn’t work, try the second one. Put a dry paper towel under the coffee maker and inspect it immediately after brewing your favorite coffee. A leaking machine will make the paper towel wet, while a good one will leave the paper dry. If any of the above is happening on your Krups machine, it is mainly because of the following reasons;

  1. Blocked nozzles
  2. Filter basket overflow
  3. A cracked or damaged water tank
  4. Thermoblock overheating the internal piping
  5. Loose plumbing and seals

Let’s dive right into how to troubleshoot a leaking Krups coffee machine and how to repair the individual components;

1. Blocked Nozzles

While you make a cup of coffee, most of the liquid empties into your cup, while some liquid is left behind. Continued use causes a gradual build-up of residue, which is bad news. After some time, the gunk and slime clog up the Krups coffee machine plumbing creating leaks. This is because the machine was manufactured to perform optimally under specific water flow and water pressure. Clogged pipes generate more pressure, which loosens the nozzles and water leaks during operation.

2. Filter Basket Overflow

Krups brand produces different coffee makers that use different types of coffee. Some have a single filter while others have a double filter, and using the wrong kind of coffee can lead to blockages and subsequent overflow. For example, drip coffee makers work with a different coffee grade than espresso makers.

Troubleshooting blocked filters require you to discover whether there are any coffee particles trapped between the filter basket and the filter paper. People sometimes forget and insert two filters into the filter holder instead of one. Double filters create a double thickness that slows the water flow rate from the filter to the spout.

Other times, you may have used a single filter, but gunk may have accumulated over time. Descaling your Krups coffee machine can make a whole lot of difference in coffee taste and brew time.

Be sure to dry the puddles on your kitchen counter before beginning the troubleshooting process for safety purposes. Move the circuit breaker to the off position before the clean-up process to avoid the danger of electrocution.

3. The Water Tank

Next, carefully disengage the water tank and inspect for any cracks or other signs of damage. Check the water tank’s plumbing to the rest of the machine to ensure the pipes and their rubbers seals are watertight and not leaking.

Another clever hack is placing a paper towel under the tank. A wet paper towel is an indicator of a leaking reservoir. Fill the tank with water, place it on the towel and leave the set up for some time.

If you detect the cause of the problem as leaking valves or piping, you can replace them to restore the full function of your Krups coffee machine. You can order brand new repair parts, including a replacement water tank from Krups, or try your luck in recycling centers or second-hand shops if you are on a tight budget.

You can also contact Krups customer support for inquiries on how to seal a problematic water tank or leaking valve.

4. Dysfunctional Thermoblock or Internal Pipework

A dysfunctional thermoblock or broken internal pipework is easy to detect when you know your way around the coffee machine’s internal system. Unscrew the back screws to expose the inner components. But avoid doing it if a year hasn’t elapsed since you bought the machine to avoid voiding the warranty.

For best results, disassemble the Krups machine and run it without the outer casing while attempting to detect water loss channels. This method is more effective since you can see all the processes at work, including the leakages, in real-time.

Be warned that water is a good conductor of electricity. Operating the machine without the outer shells makes you prone to electrocution!

To ascertain the source of leaking, carefully remove the outlet casing, starting with the back screws, followed by the rear panels to expose the inner parts. Ensure that the machine’s warranty time is over before attempting this method of detecting water leaks.

Never disassemble any electronic appliance if the power plug is still plugged into the socket. The risk is even greater with coffee machines because they contain water, creating room for short circuits and electrical shocks.

A thermoblock is a boiler, the heating component of your Krups coffee machine. Excessive heat from the heating element can negatively affect the internal plumbing, including the seals and pipework. When making coffee, the plumbing heats up, expands, and eventually contracts when the machine cools off after use.

A good sign of broken and leaking pipework is a darkish pigment on the boiler created by the continuous dropping of boiling water on the heating element.

5. The Pump and the Connected Pipes

Accidents are inevitable, and the Krups coffee machine is not indestructible. Excessive force and shock applied to the machine can drastically reduce its shelf life, either intentionally or accidentally. Knocking the machine on other surfaces may cause the valves and other water circuit connections to come loose, creating leaks.

Troubleshooting a leaking pump will require you to disassemble the coffee maker to access the pipework. Always use the correct tools for this purpose as listed in the manufacturer’s instructions. Always unplug the power cable from the power socket because water and electricity aren’t the best of buddies.

How to Solve Some of the Issues

After carefully identifying the cause of the problem, it’s time to fix it.

For coffee makers, it’s much easier and safer to replace the affected parts instead of trying to fix them.

Replacement parts for most coffee maker brands are available in repair centers or local service centers near you. After purchase, you can choose to make it a do-it-yourself project or hire a qualified service technician to complete the job for you.

While you can fix some of the damaged components, always remember that a new genuine replacement part will serve you better and for longer than an old patched-up one. For gaps in the water circuits, you can fix them using a special heat-resistant adhesive.

Other problems can be fixed at home without hiring an expensive serviceman. You can manually connect disconnected pipework and secure it firmly to prevent further leaking. Always ensure that the coffee maker is switched off and unplugged when conducting repair operations.

The drip tray can fill up and overflow for homeowners who don’t carry out regular maintenance. The water runs on other inner components before finally showing up under the coffee maker. Fixing a leaking drip tray is simple. Just empty the tray, and the leak will be as good as settled.
