Bosch hot water system

You can trust that you are receiving a high quality appliance when you choose a Bosch hot water system.

The Bosch 4000S External and 4000S Internal range of gas continuous flow hot water heaters come with an optional hot water temperature controller.

These water temperature controllers allow you to pre-set your preferred hot water temperatures for different areas within your home.

All you need to do is set your desired temperature, turn on the hot tap, and once the temperature is reached that is where it will stay until you turn the tap off again.

You no longer have to constantly turn the hot and cold taps to find that perfect medium, meaning convenience at your fingertips!

Another handy feature of the Bosch hot water temperature controllers is that they are able to determine exactly what is wrong should a fault occur within your hot water unit.

Once a fault is detected an error code will flash on the digital monitor of the controller.

This self-diagnostic feature allows for a fast and affordable hot water heater repair as the issue with the hot water heater can be seen at a glance, rather than having to pull apart the system to locate the source of the problem.

One of the error codes that may display in relation to the Bosch 4000S Internal or External hot water heater is the Bosch fault code A0.

What does a Bosch fault code A0 signify?

If error code A0 is flashing on the digital monitor of your Bosch 4000S gas hot water heater’s temperature controller this indicates that there is damage in relation to the cold and hot water temperature sensor.

How do you clear a Bosch hot water error code A0

You can attempt to clear the Bosch fault code A0 by turning the unit off at the main power, turning on the hot water tap, and then turning the power back on. If error code A0 remains then you will need to call a qualified technician to investigate and repair or replace the temperature sensor.
