Bosch Error Code A7

What Is Error Code A7?

Is your Bosch hot water system not function correctly? Is it displaying Error Code A7? Do you want to know how to fix this problem? Jim’s Plumbing gives you all the answers below.

If your hot water system is not working or is experiencing fluctuations in temperature, you may see error code A7.

When your Bosch hot water system displays fault code A7 on its temperature control monitor, it indicates that you have a faulty hot water outlet temperature sensor.

Bosch continuous flow hot water units are all fitted with an inlet and outlet sensor. These sensors measure incoming and outgoing hot water and ensure that your unit is delivering the correct temperature water to your property.

When an error code A7 occurs, it means that there is a fault in one of these sensors. A faulty sensor will result in fluctuating hot water temperatures because your unit is unable to analyse and control outgoing water temperatures.

Solving Error Code A7

To make sure that your A7 error code is correct, follow the below steps;

  • Turn off hot water heater’s power supply
  • Fully turn on a hot water tap somewhere in your house
  • While keeping the water flowing, turn the power to your heaters unit back on
  • If the error code A7 continues to be displayed, it will require the services of a professional to fix
