Multicooker emits unusual buzzing or humming from inside the base during operation.

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

Loose transformer laminations, Vibrating relay, AC mains noise, Failing power supply components

Safety: Unplug before opening the base.

Identify source: With the bottom cover removed (and extreme caution if testing live, recommended only for professionals), locate the component producing the noise.
Tighten mounting: Ensure the transformer and relays are firmly screwed to the PCB or chassis.

If the noise is accompanied by overheating or unstable operation, the main control PCB should be replaced.
