Bosch Hot Water Heater Fault or Error Code E03 Troubleshooting Guide

Bosch are one of Australia’s leading manufacturers in hot water heating and it’s easy to see why. A Bosch hot water heater is long lasting, reliable and built for the ever changing Australian climate.

Bosch hot water system

Bosch hot water systems are built smart with most hot water units featuring a self-diagnostic tool should any faults occur within the appliance.

Should a fault with your Bosch hot water heater occur a Bosch error code will display (if you have the hot water temperature controller installed). This fault code allows you to quickly see exactly what is wrong with the hot water heater allowing for a fast repair.

One of the Bosch error codes that could display on your hot water heater is the fault code E03.

What does the Bosch error code E03 display mean?

If you have a Bosch Compress 3000 heat pump installed at your property and a Bosch fault code E03 displays on the system this is an indication that there is a fault in relation to the temperature sensor at the air inlet. This temperature sensor measures the temperature of the air entering the unit and if there is a fault with this part you may experience no hot water or water that is too hot.
