A new battery might solve it

Dyson DC31... | Answered on Sep 23, 2018

If the odor is more organic, you may need to change the bag. If the smell is like burning hair or rubber then the power brush needs to be removed and cleaned. A common problem is human hair which gets wrapped around the power brush. Over time it builds up and restricts the brush from spinning freely.

Hi. The hollow noise and lack of suction suggests there is still air flow restriction. Start from the furthest point and work back towards the motor. Pull the hose off at the machine. Has high suction returned to normal? If not, open the canister and expose the filter bag. Remove the filter bag and check for a blockage or is the bag full? If the bag is not full and there is no blockage inside the inlet tube. Leave the hose and the filter bag removed, close up the canister vacuum and turn it on. Has high suction returned to normal? If not, there is probably a secondary filter or HEPA filter that needs to be replaced. I hope this helps. Please let me know what you found. Good Luck.

Check the battery.

If there is a lot of sparking, it's likely the armature is gone, especially if arcing across from one brush to the other, the motors can be bought for 15 to 20 from eBay.

The fuse in the plug is in under a small piece of plastic which sits in between the earth pin (longer of the three) and the other two shorter pins, a small screwdriver needs pushed in to lever this piece out to reveal the fuse.
