From the information here, it sounds like you do not have any suction. If this happened at the same time you replaced the bag, I'm guessing that the unit did not seal when you put it back together. Make sure the bag is seated like it should be and the cover that you removed to replace the bag is sealed and locked into place. An easy way to check this would be to remove the inlet side tubing from the machine and check the suction there. If the unit has a utility valve, be sure that it is closed. You should have good suction there unless the bag cover part of the canister is not sealing onto the rest of the unit, or the fan assembly is damaged. The latter of which is pretty rare, and it would probably make a good bit of noise. If you have good suction at the unit, then you either have a clog or an open pipe somewhere. I hope this helps. Please comment with more details if it doesn't. Good Luck!

How do I remove and replace the inverted bag filter?


Inverted filter bags can be tough to remove. The best way is to grab the bag closest to the top portion where it attaches to the canister. The bag is locked in place by a metal rings that presses out. You want to grab a portion of the bag (some bags have a holder tab) and pull towards the center. The goal is to make a C shape of the ring that is holding the bag in place. Once the bag collapse into a C shape, the bag can be removed and cleaned or replaced. The same technique is best for re-installing the new or cleaned bag.

How do I clean out nutone cv556 filter bag?


There are 3 options: 1) Use another vacuum like a shop vac to clean the filter bag while in place. 2) Wrap a trash bag around the bottom of the canister with the dirt can removed. Tighten the trash bag around the metal can and smack or shake the filter bag. This will prevent dust from escaping into the air and on you. 3) Grab the filter bag towards the top where it locks into the can. Pull the filter bag towards the center of the can to fold it into a C-shape. This can be hard to do, so do not be afraid to pull. Once folded into the C-shape, the bag should come out easily. Take the bag outside to shake off any debris. To put back in place, use the C-shape method again, and fold out to form a full circle. DO NOT wash the bags out with water.

Some of these units have had trouble with the motors and this is what causes them to shut off. NuTone has been pretty good about replacing them under warranty. 1-888-336-6151.

Nutone central vac shuts down after a few minutes of use


this is a very common problem.

If the unit is less than 5 years old and you have your bill of sale it will be covered by warranty. Although one of my customers said that there is a recall on the motor in this unit. That is totally unverified. However, if it is still under warranty, contacting broan/nutone will give you the closest warranty depot, or they may just deal with you directly.

I do recommend that both the motor and the PC board inside be changed.

Good luck,
Mark

You need to change the belt. When it does that it means it is worn. You can get replacement belts for it here:

I am unable to open the canister to remove the old bag, unclipping the 2 clips on the side does not release the canister. What am I doing wrong?


Overtime the dirt canister can get somewhat stuck. Once you unclip it, you will need to apply some force and pull down. The dirt canister should release.

If the top comes off, it will be by the motor and exhaust. Just replace it with the new one, make sure you don't mix up any wires. Also unplug it from the AC first.
