Basic Maintenance

Over time coffee makers tend to buildup residuals that start clog the passages and at some point, it becomes too much for the machine to work with. Water passages get blocked and problems start to occur such as overflowing or leakage of coffee or water. These problems tend to make a huge mess. A coffee maker can be easily cleaned using white vinegar. This is a technique that is widely used for almost every coffee maker out there in the market. White Vinegar and warm water mixture to clean the clogged passages inside of the coffee machine is an old trick of the trade that is widely used. If you have a 12-cup coffee maker, use 8 cups of water and 4 cups of vinegar. Pour this solution into the coffee maker and start brewing. After that brew with only water to wash away the lingering white vinegar taste. This will help clean the blocked pumps and passages inside the machine that were causing the coffee maker to leak.

Damaged or Loose Water Hose

This is a problem many of us face and the cause of this happening is very usual. After a year or two of continuous usage, the seals of the water hoses can melt from the heat of the machine.

Inside the coffee machine, the water needs to be heated and that heat over time can cause damage to the water hoses. Corrosion can also happen to the metal clamps holding the water hoses in place. If you find it damaged or broken it can be easily replaced with a new one and your problem is solved.

Clean or Replace Pump valve

Pump valves in your coffee machines get clogged over time due to minerals and coffee grounds. This clogging prevents the machine to pass water through which in turn results in leaking. You can either clean this pump valve yourself or call a repairer. If the pump valve is damaged then you will have to replace it.

Water Reservoir

Mistakenly overfilling the water reservoir is an issue way too common. People dunk water in without measuring and often crossing the limits written on the machine. So, after the machine is turned on the extra water leaks. The water reservoir could also sustain damages over time on the seals and water lines. Which is also very seen happening often.

Fractured Glass and Lid

If you see that your coffee carafe is leaking it could be one of two things. Either the glass has cracked and caused the leak or the lid has been damaged.

Broken or Damaged Tube Connectors

The connectors get damaged and can be fixed very easily at home. After you see leakage, you have to look where it is coming from find the leak. If it’s a connector that’s gotten loose tighten it up.
