Kenmore 700 Series Vacuum Not Suctioning

Quick Answer

The most likely cause is a full bag or a clog in the flexible hose. First, replace the bag and check the small foam filter behind it, then drop a coin through the hose to ensure it is not blocked.

I've been fixing Kenmore canisters for 15 years and honestly, they're built tough. But they absolutely tank in performance when basic maintenance gets ignored. What usually happens is one of three things: the bag's way past full, a filter's completely saturated, or someone vacuumed up something they shouldn't have. Ignore it long enough and you'll cook the motor. Not the end of the world, but way more expensive than a $5 bag.

Kenmore 700 Series Vacuum Not Suctioning

Don't panic and run out to buy a new vacuum just yet. Suction loss is almost never a dead motor. It's basically always a maintenance issue you can fix in 15 minutes with no tools. I've diagnosed hundreds of these calls and 90% of the time it's the bag, the foam filter, or a sock lodged in the hose. Here's how to work through it systematically.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Overfilled or clogged vacuum bag40%
Physical obstruction in the flexible hose or wand30%
Dirty filters (Pre-motor or HEPA)20%
Cracked hose or air leak7%
Motor fan or housing failure3%

Symptoms You May Notice

  • You're going over the same patch of carpet three times and it's still not picking up. The dirt's just sitting there mocking you.
  • There's a high-pitched whine from the motor that wasn't there six months ago. That's the motor straining against a restriction.
  • The Check Bag indicator stays red even right after you put in a brand new bag.
  • The exhaust air blowing out the back feels noticeably hot, almost uncomfortable when you hold your hand near it.
  • You disconnect the hose from the canister, put your palm over the port, and there's barely a pull at all.

Can you reset a Kenmore vacuum to clear the NOT-SUCTIONING code?

If the vacuum shut off completely, the thermal protector tripped. Unplug it first, then fix whatever caused the overload, whether that's a clog, a packed filter, or a jammed brush roll. Let it sit for 30 to 45 minutes so the motor cools all the way down. Once it's cool the protector resets automatically. Plug it back in, switch it on, and it should come right up like nothing happened.

Frequently Asked Questions

Can I wash the HEPA filter on my Kenmore 700 series?
No, and I've seen people ruin perfectly good filters trying this. The EF-9 and 53296 HEPA filters are pleated paper. Water destroys the fibers and you end up with a compressed wet clump that blocks all airflow once it dries. These filters run about $8 to $15 and you should swap them every 6 to 12 months. Got dogs or do heavy cleaning? Probably closer to every 6 months. Just budget it like a furnace filter and don't overthink it.
Why does my vacuum smell like it's burning when I use it?
That burning smell is the motor cooking itself because it's not getting enough air to stay cool. It's like running a car engine without oil, basically. If you've got a clog or a saturated filter, the motor's working way too hard and heat builds up fast. Turn it off immediately, find and clear the restriction, then let it cool for 30 minutes before running it again. If the smell keeps coming back after you've cleared everything, the motor windings might already be heat-damaged and you're looking at a motor replacement or a new machine.
The Check Bag light is green but I have no suction. Why?
That light measures pressure differential inside the bag chamber, not your whole airflow path. If there's a clog in the hose or wand, the pressure inside the bag area can still look normal to the sensor even though zero air is actually making it to the floor. So yeah, you can have a perfectly green light and a completely useless hose. Don't trust the indicator alone. Always do the physical coin-drop test through the hose and the palm test at the canister port. Those two checks tell you way more than any indicator light.
What bags should I use for the 700 series?
Genuine Kenmore Type Q HEPA cloth bags, full stop. I've seen customers try the cheap off-brand paper bags and suction drops noticeably faster because the pores clog quicker. Cloth HEPA bags hold way more fine dust before their fibers saturate, which means you actually get to fill them up before airflow dies. They're a couple bucks more per bag but you'll change them less often and performance stays better between changes. Don't cheap out on the bags and then wonder why suction's always weak.
How often should I clean or replace the foam pre-motor filter?
Wash it every 3 months if you're vacuuming regularly, and replace it outright at least once a year. Most people forget this filter even exists. Seriously, I open these machines up and find foam that's completely grey and compressed like a hockey puck. The good news is they're cheap, usually $5 to $8. When you wash it, make sure it's completely bone dry before putting it back, take at least 24 hours. Running it even slightly damp restricts airflow just as badly as running it packed with dirt.
