Tecnoeka Er1

What does Tecnoeka Er1 mean?

The temperature display shows Er1 when the connection between the cooking cell sensor and the electronic board is deactivated, or when the cooking chamber sensor itself is damaged. The oven reads this as a loss of chamber temperature feedback, so heating is interrupted to protect the appliance until the sensor signal is restored.

Symptoms

• The temperature display shows the message Er1
• Oven heating is interrupted and the cooking cycle does not heat
• No temperature reading or feedback from the cooking chamber
• Cycle cannot complete normally

Common causes

• Cooking cell sensor to electronic board connection deactivated
• Cooking chamber (cooking cell) sensor damaged
• Loose or faulty wiring between the chamber probe and the control board

Diagnostic steps

1. 01

   Stop the cycle and note the message

   Confirm the temperature display is showing Er1 and end the current cooking cycle so heating stays off while you investigate.

2. 02

   Power down before inspection

   Switch off the appliance at the upstream magnetothermal safety switch and let it cool before any internal check, as required for all Tecnoeka maintenance work.

3. 03

   Check the electronic board connection

   Verify the connection between the cooking cell sensor and the electronic board, since a deactivated connection is the manual's first listed cause.

4. 04

   Call a qualified technician

   If the connection is sound, the cooking chamber sensor is likely damaged; have a qualified technician repair or replace the sensor.

When to call a professional

Call a qualified technician if the sensor connection looks intact but Er1 persists, as the manual attributes this alarm to a damaged cooking chamber sensor that requires repair. Any work beyond confirming the message means opening the appliance and handling the control board and probe wiring, which must be done only by a trained service engineer after the oven is isolated and cooled.
