Many people register complaints about leaking Coffee machines to the manufacturers, although its reasons vary and most importantly you will not see this matter with every machine.

Keep in mind that java machines are too much used in homes and offices. Not everyone gives attention to its continuous cleaning and descaling or protecting it from other external or internal damages. So, in my opinion, people’s carelessness may be the first reason for leakage.

What Causes A Coffee Maker To Leak (Just 2 Steps Guidance)

As I have mentioned earlier, there are several causes of water leaking from bottom of coffee maker, and now it’s time to discuss in detail.

Broken or Poor Seal

One of the main reasons for leakage is some broken component inside your machine or if it’s poorly sealed. You can yourself do this checking, i.e., what part causes the problem.

The process is simple, and you need only a screwdriver or a little knowledge regarding such tasks. So, take your brewer, unplug it, remove its water tank, check and ensure the brew basket is empty. Remove the brewer’s back panel, check each part, and find out the problem.

Keep in mind that sometimes the problem may occur on the inner side of the machine. So, check it as the procedure is similar, put your machine upside down, remove the cover and check the machine.


The most crucial point here is that if you are struggling with the leaking coffee maker problem right after buying it, use the warranty to replace any part instead of opening it yourself.

Water Tank And Boiler

Another reason for leakage is any issue in the water tank and boiler. So, to check the former, remove it from the machine and check if there is any physical damage to it. Also, check the points where the reservoir joins the machine.

Another main problem is the deterioration of the gasket that seals the joint between the machine body and the water tank. This problem has a solution, but you have to go to a market, find a hardware store, and buy a gasket that is entirely compatible with your machine in shape and diameter.

If you are bound to use hard water as there is no bottled or filtered water available, your delicate java machine water tank and boiler may damage easily. To avoid this situation, buy the best coffee maker for hard water.

How To Fix Leaking Coffee Maker (Step By Step Guide)

How To Fix Leaking Coffee Maker

After discussing the causes now it’s time to fix leaking coffee maker problem. Let’s discuss them one by one. 

Clean Your Machine

If your coffee maker appears to be blocked, use a solution of white vinegar and water to clean it. You can do it simply by adding one-half white vinegar and one-half water into the water reservoir of your java maker.  Turn on the machine and allow the solution to go through a brewing cycle as if you were creating a pot of java. Thus, you will be able to dissolve any build-up in your machine. This process may remove the clog and stop the leakage if it is due to a blocked pump.

The machine needs cleaning often, and if you haven’t cleaned it for long, you may need to run the vinegar through many cleaning cycles to dissolve all of the build-ups. After removing the solution, rinse your java maker by continuously brewing simple water 3 to 4 times.

Examine The Pump Valve

Remove the java machine from the outlet and inspect the pump valve. If you find out that the water will not be able to rise and flow through the fill tube, check the pump valve because it is either due to any damage to it or of clog.

When you switch on the machine, the water has to go somewhere. If it does not find a way to flow through the fill tube, you will find it out onto the tabletop. If the problem is in the pump, you’ll have to replace it entirely. Otherwise, double-check your machine to ensure that there are no coffee grounds or mineral deposits that cause blockage.

Check The Brewing Switch

There may be an issue with a brewing switch from time to time. It’s near the bottom of the base plate, on the inside. To disconnect the base plate, you’ll need a screwdriver. Remove the bottom plate and find the brewing switch. If there is any problem with it, it causes water or coffee to overflow.

To check the working of the brewing switch, you need a volt-ohmmeter. So, touch the RX1 scale with the tester. If the value is 0 ohm, you can confidently say that your brewing switch is in good working order.

If the reading is in number above zero, the switch is faulty, and it’s time to replace it with a new one. You can not perform this task yourself; thus, you have to contact the company’s repair service in this case.

Take a Look at The Tube Connectors

Another issue that causes your java machine to leak and overflow is a damaged tube connector. While checking if you find the elbow of the tube connector broken and causing leakage immediately, swap out the old elbow for a new one.

If the tube connector leaks, you should replace both the tube and the elbow to ensure that the components correctly fit together. Remember, cleaning the surface thoroughly is also necessary to correctly install the new tube connection and elbow. If you ignore these defective tuber connections, the leak will likely persist for an extended time.
