Why is my Bosch Water Heater giving me only cold water when the neon light is on?

If your Bosch Water Heater is producing only cold water, but the neon light is on, it could be due to these reasons: * The water flow rate is too high: Adjust the flow rate using the hot water outlet service valve. * The flow rate is correct: Adjust the temperature dial on the front of the cover. * The inlet water temperature has dropped: Adjust the flow rate with hot water outlet service valve.
