Electrolux Cooktop Error Code E30

E30 on an Electrolux cooktop means the 3-cook-zone induction module has detected AC input voltage that is too high for safe operation. The cooktop's protection system triggers this fault to prevent damage to the induction module's internal electronics. The cause may be an actual overvoltage condition from the home electrical supply, a wiring issue at the input connections, or a failed filter board within the module.

Resetting the cooktop by cutting power at the circuit breaker may temporarily clear the E30 code, but the fault will return if the underlying cause has not been resolved. If the supply voltage remains too high, or if the filter board is faulty, the error will reappear as soon as the cooktop is powered back on and the module detects the same condition.

Repair costs vary depending on the root cause. If the issue is simply a loose terminal connection or an incorrectly installed jumper, a service call fee may be the primary expense, typically in the range of $75 to $150. If the filter board in the 3-zone induction module needs replacement, parts and labor combined could range from $150 to $400 or more depending on parts availability and local labor rates.

Some aspects of diagnosing E30 are within reach of a knowledgeable DIYer, such as checking that the cooktop's input terminal screws are tight and that jumpers are correctly installed. However, measuring AC supply voltage and replacing the filter board in the induction module involves working with potentially dangerous line voltage and internal components, so those steps are best handled by a qualified appliance technician.

You should not attempt to use the cooktop while E30 is active. The error indicates the induction module has detected an overvoltage condition and has disabled operation as a protective measure. Continuing to force operation under an overvoltage condition could damage the induction module's power electronics or create a safety hazard.
