What is a relay in a coffee machine

A relay is an electronic switching component that, on command from the control board, turns the power to the coffee machine's power components on and off, most often the boiler heating element or the pump. It acts as a reliable switch that can withstand the frequent and rapid switching needed to maintain a stable temperature without wearing out mechanical contacts.

Signs of wear or failure

• The coffee machine does not reach or hold the set temperature
• Heating switches on and off irregularly or not at all
• The display shows an error related to heating or the pump
• You can hear clicking, or notice a burnt smell from the electronics

When it's time for a replacement

A damaged relay can cause the heating to stay permanently on or, conversely, switch off completely, leading to poor coffee quality, longer brewing times, or in the worst case, damage to other components of the coffee machine. Timely replacement prevents higher repair costs for the electronics.

Relays differ in type, switched voltage, and mounting method, so before buying, check compatibility with your specific coffee machine model in the product table.
