This is a follow-on video for solving F03 errors in Bosch Condensing Dryers. I have a shorter video to solve F03 quickly quickly (15-30 min), but use this video if it comes back or you just want to do it right the first time (30-60 min). I show how to remove the sump pump without removing the side panel, and clean underneath it. You can't see most of the algae beneath unless you remove it. I also clean out the pump itself.
