Ikea Supply Voltage Too High

Induction cooktop shows E3 and shuts down during use

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

Line voltage above specification, Incorrect wiring (e.g., 400 V 3-phase miswired), Power surges

Safety first: Only a qualified electrician should measure and correct mains voltage issues.

Measure voltage: Have an electrician verify the supply voltage at the cooktop terminal block matches the rating plate (typically 220–240 V AC).
Correct wiring: Ensure the cooktop is wired according to the Ikea installation diagram for your region (single-phase or two-phase as specified).
Surge protection: Consider installing surge protection if voltage spikes are common.
