Speaking from experience, had a similar issue. Dial was messing up (no drainage ditch involved in this fairy tale) and I gave FJ customer service a holler. They told me a few options. I could send them back and they can give them a look (for warrantee issues, etc...) or I could try and fix it myself. My handy-man skills stop after Lego construction and replacing a light bulb so I decided to send them back. Got them back repaired and they work perfectly ever since!
