Question about Shop Vac Vacuums
I had a flood in my basement and was using the 16 gallon shop vac 5.0. All of a sudden it started making a loud noise. turned it off. I noticed the water was quite high, so i emptied it. It now continues with the terrible noise, and smells like it is burning. Is it ruined? What to do?
If the ball was stuck and you sucked water into the motor it could cause it to smell like it's burning if it ruined the motor

Hi! Highly unlikely that you need a new motor. Highly likely that you need new carbon brushes. The smell is caused by excessive sparking between the worn brushes and the copper commutator segments. Most carbon brushes (and from memory I suspect this includes Henry's) have a copper wire buried in their last few millimeters, and you really need to change them before that becomes exposed. The longer you run it like this, the more likely you are to damage the commutator, so change them sooner rather than later. When you change the brushes, you can smooth off the commutator with very fine abrasive paper (the objective is to smooth it, not scratch it!), and then blow all the dust away (or **** it away if you have another vac, of course). Incidentally, you don't say if you are using a paper bag in your Henry. Some people, because the top-hat filter is so good, try to manage without a bag. This is false economy! You should always use a bag. I hope this helps! I value feedback, so please remember to rate this response.

SOURCE: vacuum is making a loud noise
Is the smell rubber or electrical. If rubber then the belt is slipping and needs to be replaced, they stretch after awhile. Also is the brush roll turning freely, or is it bound up, it may have to be replaced. If the smell is electrical, then probably the motor is going bad and will have to be replaced.

If you remove the motor, you will see that the wires that go from the switch to the brushes. On one side there is one wire connected directly to the brush. On the other side the wire goes to a plastic plug with a second wire going to the brush. This is probably where the problem is. This is a fusible link and it has most likely melted creating an open in the circuit. I put a piece of solder where the link was and the motor ran BUT the brushed arced like a sparkler. Upon further examination the brushes were crumbling apart. I have been unable to find replacement brushes.
This machine has a five year warranty. I called Shop Vac Customer Service 1-888-822-4644 and they sent me a new motor.
I had a Shop Vac QL50EIC which had exactly the same problem but the warranty was expired so that I had to buy another motor for about $50.

It sounds like the motor has overheated and has now been irrepairable damaged.
The motor has a built in over-current trip to protect itself (and you if it seriously overheated and caught fire). This normally automatically resets itself, however if the motor has just about had it, the moment it is switched on, it just trips again.
The primary cause of motors overheating is that the filters are not cleaned or replaced frequently enough. Dont be fooled by Dyson's "lifetime filters". They need to be regularly cleaned and replaced when necessary.
Replacement motors are avaible on eBay for about £25, however repalcing one requires good DIY skills and tools.
Have a look at www.dysonmedic.com and see if you feel you can tackle it yourself. If not, take it to a repair shop or call the Dyson helpline.

Testimonial: "thanks so much for taking the time to reply...sounds like we need a replacement!!!...will get the dyson ball this time..hope it's good! thanks again!"
Your belt is worn and stretched and so it is slipping on the motor drive shaft. That is why it is noisy and smells like burning rubber. You simply need to replace the belt. You can get replacement belts here:
