Wet spots around the espresso machine do not always mean a serious fault. Sometimes it is enough to put a drip tray or water tank. However, there are situations when leaking signals a more serious problem. We suggest what to look for.
Basic control – start with the simplest things
When you see the water under the espresso machine Check the drip tray first. The machine during rinsing and cleaning uses a lot of water, which must flow somewhere. If you do not empty the trays regularly, the water will begin to overflow. The same applies to coffee grounds – when it is not properly inserted, the water can get out sideways. Also check the water tank – sometimes just remove it and put it back, pressing to the end.
Valves and seals are a common source of problems
Troubles often start with valves. In machines with a removable water tank, the valve can be used or not closed correctly by stone settlement. Check if dirt or stone remains are collected there. Similarly, the water flow controls can wear out, causing uncontrolled leaks.
Water tank – check its condition
The tank itself can also be a source of the problem. Plastic containers are exposed to cracks, Especially when we often take them out or accidentally tap them on the countertop. Even a small damage can lead to leakage. Check carefully if the tank has cracks or cavities.
Stone
Stone is the most common cause of leakage of machines. It not only clogs the wires, but also destroys seals and valves. Check the water hardness in your home regularly – special test strips are used for this. On this basis, set the appropriate hardness level in the espresso machine and follow the dates of descaling. Ignoring messages about the need to descend is a simple way to a serious failure.
Problems with pump and water system
An incorrectly working water pump can disturb the pressure throughout the entire system. When the pump does not maintain the proper pressure, the water may get out in unforeseen places. A similarly clogged brewer and dirty strainer can lead to leaks – coffee grounds can effectively block the correct water flow. What you can do in this case is in -depth cleaning of all places you have access to. Sometimes the problem is loose or cracked hoses, which you can try to press or replace.
Too finely ground coffee can hurt
Hardly anyone realizes that Too finely ground coffee can damage the coffee machine. When the coffee is ground to dust, the pump must use more pressure to push the water. This can lead to the unsealing of the system and in consequence – to leaks. If the coffee machine is leaking due to too finely ground coffee, it is worth trying to set the grinding to slightly thicker
