What is a signal light socket

The signal light socket is a small electrical holder that secures the indicator light on the coffee machine's control panel. It ensures electrical contact between the bulb and the machine's wiring harness and holds the bulb firmly in place in the panel.

When the part stops doing its job

When the socket oxidizes, cracks, or loses contact, the indicator light flickers, glows weakly, or goes out completely, even though the bulb itself is fine. You may also notice the bulb becoming loose in the panel or intermittent contact when touched or when the machine vibrates.

Why you shouldn't put off the replacement

A faulty indicator light makes it harder to monitor the coffee machine's status, such as power on, water heating, or error messages. Replacing the socket is a simple and inexpensive fix that prevents unnecessary troubleshooting elsewhere in the wiring.

How to choose the right part

• Check compatibility with your specific model in the product table.
