A Klasse Windshield Washer Heater Problem

I had a similar problem with my A Klasse last winter, where the washer fluid wouldn't spray when it was freezing. I didn't get an error message, though. Have you checked the fuse for the washer heater? Also, are you using winter washer fluid?

Thanks for the reply. Do you know the specific location of the fuse? I couldn't find it in the manual. I am using winter fluid rated to -20°C. The error message points to a heating element circuit malfunction.

About the fuse location, I don't recall exactly which one it was. I found it using a fuse tester. Since you're getting an error about the heating element and are using the correct fluid, it's likely the heater or wiring. Given the error, a workshop visit might be best. The 95€ estimate sounds reasonable for the repair.

Thank you for sharing your experience. I'll take it to a workshop for diagnosis and repair. The 95€ estimate matches my expectations, so hopefully, that will fix it. Thanks again for the help.
