The loss of water from a coffee maker is one of the most common problems, especially in coffee makers who work with high pressure. The ones that happen the most are espresso machines and capsule machines due to their technology and extraction methodology. Drip coffee makers or Italian or best pour over coffee makers suffer less from these types of failures.
Causes of water leakage underneath
When the coffee maker is started, it is immediately observed that a small well of water begins to form under it. This is possibly due to a broken component or a seal that has expired or lost its original position. To find out, the first thing you should do is disassemble the coffee maker to verify where the leak is occurring.
To disassemble it, it is necessary to have the appropriate tools such as screwdrivers and thus remove the rear and upper panels. Of course, this depends on the model of coffee maker you have. They are reminded that this process should only be carried out if the guarantee has already expired; otherwise, it is better to take it to the brand’s technical service.
The components commonly susceptible to water leakage are the boiler through which the water passes for heating or the water tank. To check the water tank, remove it and check that it is not broken anywhere. You can also check if the connections to the body of the coffee maker are in perfect condition.
The most common problem is the rubber gasket that joins the tank and the coffee maker because it loses its physical properties over time. If it is damaged, it should be replaced by one in perfect condition with the right diameter to make the correct seal.
If the leak is from the boiler, it may be caused by the seal that joins the thermal resistance with the pot itself. If it is damaged, it will let water escape generating a dark stain on the boiler walls, generating dripping at the bottom.
Another common cause of water leakage in coffee makers is that some element is loose or out of its initial position without any component being damaged. It is only sufficient to relocate the loose element to its initial position and make the corresponding adjustments in these cases.
Once the repair is complete, it is advisable to clean the coffee maker thoroughly. The calcium residues and dirt cause the water to be diverted from the places where it must pass, generating possible leaks reflected in the lower part of the coffee maker.
