My water heater COB 10 turns off after 3 or 4 minutes of use. It takes 2 to 3 minutes to turn it back on. What is happening? Is it in safety mode? Thank you for your answer. Regards, Yvan Dubreu.

Based on the information in the manual for the Cointra Optima COB-10 b water heater, the safety element called T.T.B. is responsible for ensuring the proper evacuation of combustion products. If there are disturbances in the evacuation, the T.T.B. device will interrupt the gas supply to the burner. To address the issue of the water heaters not firing up, you can follow these steps: 1. Check the evacuation of combustion products by examining the burnt gas outlet. 2. If the T.T.B. device is activated when you turn on the water heater, it indicates a problem with the evacuation. In such cases, it is recommended to revise the evacuation system and ensure it is functioning properly. 3. If there is damage to the T.T.B. device, it is important to use only original spare parts for replacement to ensure proper functioning. 4. If necessary, the T.T.B. device should be replaced by experts. Please note that these instructions are general and may vary depending on the specific model of the water heater. If you have any further questions or need assistance, please let me know.
