After I got so much help from this list on repairing my 400, I got up the courage to see if I could fix my old Dirt Dog. The Dirt Dog is still covered by Hammacher
Schlemmer but I hate to return it because I liked it so well before it died. Anyway, when I got through diagnostics past the test 9, I was feeling pretty good. But then at test ten, it made a sickly toned noise and none of the tests past that seem to do much of anything at all.
When I try to use it , it moves a little as if it is in molasses, and attempts to circle and wall follow but just can't seem to do it. The front wheel does move freely and the wheel holder is clean. Manual rotation shows no change from the solid red light.
I imagine my advise will be to send it back, but having just learned how to use the diagnostic tests, I really wanted to try to see if it could be repaired first.
What do ya think?
