Any more back ground to what may have caused this short circuit? Water, hit something, overheated,

Ouch… few yrs later… Initiate lift away, lift it away and Take apart entire head until you have full brush roll access. Take apart the white mounting part as well. A few difficult moves coming up once you have wires free. Be careful with separating clipped tubes from each other. Dont want to break them. If you fail 3 attempts stop and get some towels/ large rubber anything material to gain grip with one hand, straddle the pieces with legs, pin it down, phone a friend, sos someone special. Once its separated you can GINGERLY cut out the entire thing or just a small section depending on how Old/damaged the tube is. After that i recommend specialty epoxy since we want this to last for a hot minute or ten. I used jb weld plastics but I also sprayed a plastic protection/flexi-cover all over and inside the tube since it takes so much punishment. Walaa
