De'Longhi Power Supply Instability Under Load

Display and lights flicker or reset when heating starts; cooker may shut off unexpectedly.

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

Weak mains supply or overloaded circuit, Loose power cord connection, Failing internal power supply on PCB, Intermittent thermal fuse or relay

Safety first: Avoid using the cooker on the same circuit as high-power appliances (kettle, microwave) if flickering occurs.

Try a different outlet: Plug the cooker into a dedicated wall socket with no extension cord.
Inspect cord and plug: Ensure the plug fits tightly and the cord is not damaged.
Observe pattern: Note if resets occur only when heating starts or randomly; this helps diagnose whether it's load-related.

If flickering persists on a good outlet, the internal power supply or relay may be failing and should be checked by a technician.
