Resetting Webasto F12 lock out
Finally figured out how to do the Webasto F12 error reset on a 2019 R-27.
Wow. I finally got it. The reset process is super finicky. here
First, pull all 3 solar panel fuses behind the helm (aces add via the bathroom)
Second, start the Webasto heater
Third, immediately turn off the House batteries
Fourth, immediately pull all three Webasto fuses
Fifth, count to 20 seconds
Sixth, reinsert Webasto fuses
Seventh, turn on house batteries
Eighth, restart Webasto heater here

Have you checked the manual. If you don’t have one you can find it as a download under Ranger Technical Manuals.

To be safe, I would not mind removing all fuses when laying up for the winter (I killed one battery last winter). Is there any concern about doing this? Would this ensure that nothing would be still drawing juice? I know I can remove the terminals, but given the space and design, removing the terminals would be a big PIA. [links]
I've only had the Wallas diesel stove heater and engine heater and have had no experience with the Webasto heater.

1) How quickly does this heater produce useful heat ?
Just following up. I finally found the fuses on our R23! They're in a square hole under all of the control panels at the back of the cave. here
I'm going to contact Steve at Sure Marine for more suggestions and procedures. He also suggested I service the unit by changing out all the gaskets. I bought the kit from him but didn't install. I'll do that next if the resets don't take. At least I got heat for a little while. I'll update what I find. [links]

We're getting the F-01 fault code on our Webasto heater . I understand I need to remove the fuse in order to reset. Can someone tell me where the fuse is located on the R23?
