A note to Reassembly- be very careful that the 3 wires coming out by the right wheel are tucked into the protective guide hole on the wand end.(1/2" circular hole with slit for wires) Then when you seat the assembly in the body they're not pinching and still in the guide hole.
I had to do a repair because I had previously not paid attention to the wires and the power wire pinched apart when I replaced the hose.
