ER22 Error on Teka Induction Hobs

What the ER22 error means on a Teka induction hob

The ER22 error on a Teka induction hob indicates, in most models, a communication or reading issue in the touch control system. The electronics detect inconsistent values coming from the control panel and, for safety, the hob locks operation.

This code often appears when the hob interprets that the touch keypad is not responding reliably, which can happen even when there is no serious fault.

The most common situations in which ER22 appears are:

• Presence of persistent moisture under the glass.
• Dirt or grease residues interfering with the touch panel.
• Prolonged use with high temperatures near the controls.
• Electronic desynchronization after power outages or micro power cuts.

In short, ER22 usually means the hob cannot correctly interpret the user’s commands, so it protects itself by blocking interaction.

How to clear the ER22 error step by step

Before considering a repair, it is recommended to follow this ordered process to rule out the most common causes.

1. Turn off the hob and carefully clean the control panel
   • Turn off all cooking zones.
   • Clean the glass with a soft, slightly damp cloth.
   • Dry the control area completely.
2. Let the hob rest
   • Keep the hob off for 5–10 minutes.
   • This allows the sensors and electronics to stabilize.
3. Perform a full electrical reset
   • Switch off the circuit breaker for the hob’s circuit.
   • Wait 2–3 minutes before turning it back on.
4. Avoid accidental contact
   • Do not place cloths, lids, or containers on the control panel.
   • Do not keep your fingers on the controls unnecessarily.
5. Check whether the error always comes back
   • If ER22 appears immediately upon switching on, there may be an internal fault.
   • If it appears only occasionally, it is usually an environmental issue.
6. When to contact technical service
   • The ER22 error does not disappear after cleaning and resetting.
   • The panel responds erratically or stops responding.
   • The code appears even when the hob is cold.

   In these cases, it may be necessary to inspect the touch keypad or the control electronic board.

When ER22 appears only occasionally, it is usually resolved with cleaning and a reset. If it becomes recurring, it is advisable to act before the panel becomes unusable.
