Bosch Hot Water Heater Fault or Error Code A9 Troubleshooting Guide

Is a Bosch error code A9 blinking on the digital monitor of your temperature controller for your continuous flow hot water heater? This fault code A9 signifies that the hot water outlet temperature sensor is not fitted correctly within the unit.

When the Bosch error code A9 is displayed you may also experience no hot water or fluctuating hot water temperatures.

The water temperature sensors fitted within the Bosch tankless range of gas hot water heaters are an important safety device. They are used to monitor the hot and cold water flow settings to provide you with your pre-set water temperature when the water reaches your tap.

Another reason that may cause an A9 error code on your Bosch hot water system is a low incoming gas pressure.

You can attempt to clear the error code A9 display yourself by turning the power off to the appliance, turning on your hot water tap and then turning the appliance power back on. You can also check your gas supply pressure by turning on your gas stove.  If the flame seems lower than usual check that your gas valve is open.

If the A9 fault code remains then you will need to call in a qualified technician to provide a repair.
