Bialetti Thermal Cutoff or Auto-Off Circuit Malfunction

Electric Bialetti coffee maker auto-shuts off too quickly or will not stay on long enough to brew a full pot.

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

Overly sensitive thermostat, Faulty auto-off timer circuit, Poor contact in on/off switch, Overheating due to scale

Safety first: Unplug the machine before opening any covers.

Descale: Scale on the heater can cause localized overheating and early thermal cutoff. Run a full descaling cycle.
Check switch: Ensure the on/off switch clicks positively and does not spring back. Replace if it feels loose or intermittent.
Observe behavior: Time how long the machine stays on. If it shuts off within seconds, suspect a faulty thermostat or control board.

Replacing thermostats or modifying auto-off circuits should be done by a qualified technician.
