Bosch Error Code 90

Bosch Hot Water System Fault or Error Code 90 Troubleshooting Guide

Bosch gas hot water systems have an error code feature. If there is a fault, an error code is displayed on the system or temperature controller.

If you have a Bosch system, an error code you may come across is error code 90.

What Does The Bosch Hot Water System Fault Code 90 Indicate?

An error code 90 on your Bosch gas hot water system indicates that there is a problem in relation to abnormal combustion, or a low gas supply pressure.

You can try troubleshooting the problem by following these steps:

  • Pressing the ‘off’ button on the water temperature controller
  • Turning on a hot water tap
  • Pressing the ‘on’ button on the water temperature controller

If error code 90 remains then you will need to call a qualified plumber to assist.
