Tecnogas induction cooktop shows Er03 and the touch controls do not respond.

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

Child lock function enabled, Liquid on touch surface, Faulty touch sensor PCB

Steps:

Disable child lock: Press and hold the key-lock symbol (or the designated combination) for 3–5 seconds until the lock indicator turns off.
Clean the glass: Wipe the control area with a dry, soft cloth to remove spills or condensation that may be triggering the sensors.
Power reset: Turn off the breaker for 1–2 minutes, then restore power and test.

If Er03 persists with a clean, dry surface and lock disabled, the touch control PCB may be defective.
