The performance indicator came on and when I changed the dirt bag and turned it back on the indicator light was still on and the vacuum doesn't suck - this is a Kenmore Elegance vaccum with hepa filter.
Hi Deb
If you check towards the lower rear of the machine there should be a small grill if you unclip it behind is a filter,i'm sure cleaning this will resolve your problem,unless you have hoovered up over a wet carpet. neil
