Bosch Error Code F9

Error Code F9 Troubleshooting Guide

Most Bosch hot water systems are equipped with technology that detects faults. These faults are displayed as error codes on the system’s water temperature controller. One error code you may encounter is error code F9. Systems known to show this code include:

  • Optiflow
  • Optiflow Professional Internal
  • Optiflow Professional External

What Does The Bosch Hot Water System Error Code F9 Mean?

The Bosch error code F9 indicates that your system’s safety solenoid valve has been disconnected. This valve is important as it controls the flow of gas or liquid within the hot water unit. Usually, your water system will cease to operate in the event of a Bosch error code F9 display until the F9 fault has been rectified and cleared.

To make sure the error code isn’t simply a glitch, you can try the following steps:

  • Press the ‘off’ button on the water temperature controller
  • Leave the system for 20 seconds
  • Press the ‘on’ button on the water temperature controller

If error code F9 persists, you will need to call a qualified plumber to address the problem. It is important to note that you should not attempt to handle or fix the safety solenoid valve yourself. Doing so can cause greater damage, and will void any warranty you have on the water heater.

So quick!

Jayden was sent to fix my washing machine taps. He was polite and friendly, and explained what needed to be done. It was a bit more expensive than I expected, but from my call for service to the job being completed was only two hours. I would definitely recommend!
