Rocket Espresso User Interface / Switch Failure

The machine does not respond to front panel switches or buttons, but the power light is on.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty brew switch or button, Broken wiring harness to the front panel, Failed low-voltage supply to controls, Stuck microswitch

Safety first: Unplug the machine before removing the front panel or touching internal wiring.

Test individual controls: Try each switch (brew, steam, hot water) to see if any respond. Note which functions are unresponsive.
Inspect wiring: Remove the front panel and check the harness connections to each switch or button. Reseat loose connectors.
Check switches: Use a multimeter to test the continuity of suspect switches when operated. Replace any that do not make reliable contact.
Control voltage: If all switches are unresponsive, the low-voltage supply from the control board may have failed, and the board may require replacement.
