How to fix a heater lock-out on a Webasto Water Heater?
- TTyler JonesAug 13, 2025
If you experience a heater lock-out with your Webasto Water Heater, there are several actions you can take. First, clear the error memory using the "Clear fault memory and heater interlock" command located in the "Error memory" menu. Alternatively, you can delete the heater lock-out by clicking the "Delete heater lock-out" button, also found in the "Error memory" menu. As another option, you can remove fuse F3 for at least 10 seconds and then reinstall it.
