Rebuilt DC 25 but now low suction and wand does not work.
« on: December 26, 2014, 07:23:57 PM »
First - I noticed that I must have thrown away the pre filter. Opps. Could that be causing the low suction?

A while back I was drowsy from being away for more than 30 hours (work) and just after I went to sleep, my wife woke me up to show me what my daughter did. Daughter took a job of OJ and play tea party with it. It was everywhere.

My groggy nature allowed me to use my DC25 to pick up the OJ. Bad move as there was mold throughout the DC25.

I order a new cleaner head, yolk, and the other part that connects to the main housing. I ended up with leftover screws - 5 silver ones, one black, and one round cup for use with black screw.

The DC25 runs correctly but the suction is low. Nothing is blocked. What could the cause be?

What's the suction like via the hose and the suction at the button without the electrical brush head? Same or different?
Also check the the seal at the bottom of the cyclone is intact as this may cause the bin to not be closed properly, so the cyclone bin will not seal to the machine. This happened to my dc25 the other day because the dirt bin was a little too full :/
DC14s are tanks, just need a slightly longer motor life. Do plastic parts often break on DC14s? Nope. DC41- Sexy looking futuristic and powerful machine. Just needs a better designed cleaner head wheel and cyclone clip along with a dense metal rod in the chassis.

I think the flow is the same from the head to the hose but I dont have an air flow meter.

The seal at the bottom of the cyclone looks to be sealing. I cleaned that part and I see no signs of air leakage.

OK, the pre motor filter missing wont reduce suction as it does not seal the cyclone lid lip.
I assume the suction is good from the hose and bottom? If so then the cleaner head might have a missing seal where it connects
