Wall-mounted boilers are a popular choice for providing heat and hot water efficiently in many households. However, like any other appliance, they can sometimes develop faults. One common issue is the appearance of the "Er wrench" symbol on the boiler's display. This article aims to explain the meaning of this symbol, how to troubleshoot and fix the problem, and provide contact information for assistance if needed.

Understanding the "Er wrench" symbol

When you see the "Er wrench" symbol on your Bosch wall-mounted boiler, it indicates that there is a malfunction within the system. The exact cause can vary, but it typically implies an issue with one of the boiler's components or sensors. While specific error codes may differ between models, the general message remains the same: there is a problem that requires attention.

Troubleshooting and fixing the issue

Before reaching out for professional help, there are a few steps you can take to troubleshoot and fix the "Er wrench" error on your own:
