What the E.24 error code actually means

Your Ariston cooktop has detected a fault with the temperature sensor that monitors the heat level of the internal power supply component for one of the cooking zones. The sensor is sending a signal that the cooktop's electronics cannot interpret correctly, so the cooktop has shut down to protect itself. A technician will need to test the sensor and its wiring to find and fix the problem.

Questions people ask about E.24

What does E.24 mean on a Ariston cooktop?
The E.24 code means the dissipator temperature sensor for the supplying generator has been detected in a short circuit condition. The dissipator sensor monitors the heat sink of the induction power electronics, and when the control board reads a resistance value consistent with a short circuit, it shuts the cooktop down to prevent damage. The fault points to either the sensor itself, the wiring harness, the connectors, or the control board.
Is it safe to use my Ariston cooktop while E.24 is displayed?
No, you should not attempt to use the cooktop while E.24 is active. The error indicates the thermal protection sensor for the power supply generator is not functioning correctly, meaning the cooktop cannot reliably protect itself from overheating. Continuing to operate it could risk damage to the internal electronics or create a safety hazard.
How much does it cost to repair an E.24 error on an Ariston cooktop?
Repair costs vary depending on which component has failed. Sensor replacement tends to be a lower-cost repair, generally in the range of $80 to $200 including parts and labor. If the control board requires replacement, costs can rise to the $200 to $500 range or higher. Getting a diagnostic assessment from a qualified technician is the best way to estimate the repair cost for your specific situation.
Can I fix the E.24 error myself?
Some basic checks, such as inspecting the wiring harness for visible damage or cleaning corroded connector pins, can be done by a confident DIYer after unplugging the cooktop. However, replacing the dissipator temperature sensor or the control board requires disassembling the cooktop and working with internal electronics, which is typically best left to a qualified technician. Always disconnect power completely before inspecting any internal components.
Will resetting the cooktop clear the E.24 error?
A power reset by switching off the cooktop at the circuit breaker and restoring power may temporarily clear the fault display, but if the underlying short circuit condition in the sensor or wiring remains, the E.24 error will return as soon as the cooktop attempts to operate. A reset does not repair the faulty component and is not a substitute for proper diagnosis.
