Trying to FIX: Karcher Dirt Blaster Lance NOT Spinning

Hi, this 'trying to fix' videos shows my brother Paul and I attempting to repair a faulty Karcher pressure washer lance. This lance is called a Dirt Blaster and it has stopped spinning, it also causes the pressure washer to cut in and out.
Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things.
I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series.
Many thanks, Vince.
