UDM breaks in the middle of a detail

So I was working on a client's car when I noticed a burning smell coming from the UDM. Immediately I turn off the UDM and as I lifted it off the car, I find that the pad was still sitting on the car. After further inspection, I find out that the whole counterweight assembly has been seperated from the UDM. Looks like it melted right off. Here are pics of the destroyed UDM. Fortunately, I have the PC to finish off the job.







I purchased the UDM from Autogeek. Is there any warranty on this item?

Fortunately, the pad and the counterweight assembly was sitting on top of the hood as I lifted up the UDM. I did notice that the motor was losing power. Weird, because I've put more pressure on the udm in the past and the motor was fine.
