Причины и профилактика поломок

Засорение гидросистемы происходит при некорректном обслуживании. Например, если не производить регулярную декальцинацию, не очищать детали от остатков кофейного масла, не прочищать диспенсер, кофеводы. Также к засорению ведет применение слишком жесткой воды с массой солевых примесей.

Электронные компоненты чаще всего ломаются при значительных сбоях напряжения. Однако такие коды ошибок можно предупредить, если подключать кофемашину через стабилизатор.

Кофемашина может сломаться как при неверном использовании, так и вследствие производственного брака.

Заварное устройство забивается, если нерегулярно промывать клапан под проточной водой, не удалять остатки кофейного масла с кремоклапана, не смазывать прибор.
