Why do the main burners go out during hot water use in my Bosch GWH-425-EF-N?

If the main burners on your Bosch Water Heater go out during hot water use, it could be due to several reasons. One potential cause is deficient exhaustion of flue gases. Another is a flow rate that has diminished below the activation rate; ensure that the water flow meets the required amount to activate the heater. Unbalanced pressure in waterlines, which can be resolved by ensuring faucet aerators or shower heads are free of minerals, can also cause this issue. The ECO (overheat sensor) might have tripped due to overheating, or the minimum inlet pressure on your well pressure tank might be inadequate, so check the inlet water pressure.
