ER31 Error on Teka Induction Hobs

What the ER31 error indicates on a Teka induction hob

The ER31 error on a Teka induction hob is usually associated with a configuration fault or an incompatibility detected in the electronic system. The hob detects an abnormal condition during start-up or operation and blocks use to prevent damage.

This error is not directly related to everyday use, but rather to the electrical environment or internal configuration.

Situations in which ER31 commonly appears include:

• Incorrect or incomplete electrical installations.
• Incorrect voltage configuration (230 V / 400 V).
• Desynchronization after a prolonged power outage.
• Initialization failures in the electronics.

In practical terms, ER31 indicates that the hob does not detect safe conditions to start.

What to do to fix the ER31 error

This error requires a more technical approach than other codes, although some steps can be performed without dismantling the hob.

1. Switch the hob off completely
   • Disconnect the hob at the electrical panel.
   • Wait at least 5 minutes.
2. Check the electrical installation
   • Confirm that the supply voltage is correct for the model.
   • Check that the terminal block links/jumpers are correctly positioned.
   • Make sure the terminals are firmly tightened.
3. Avoid repeated resets
   • Do not try switching it on and off repeatedly.
   • This can prevent the electronics from reinitializing correctly.
4. Check whether the error always appears when cold
   • If ER31 appears as soon as power is supplied, it points to a configuration issue.
   • If it appears after running for a while, there may be an internal fault.
5. When it is essential to call a technician
   • The ER31 error persists after checking the installation.
   • The hob does not allow any type of power-on.
   • The code appears after a recent replacement of the appliance.

   In these cases, it is often necessary to reconfigure or replace the electronic control board.

6. How to prevent it from happening again
   • Always follow the manufacturer’s electrical specifications.
   • Avoid temporary or improvised connections.
   • If there is electrical instability, use appropriate protection at the breaker panel.

The ER31 error does not usually resolve on its own. Detecting it early and checking the installation helps prevent more serious damage to the hob’s electronics.
