No power getting through

The part of the hose that attaches to the vacuum should push on the switch on the front of the vacuum so it won't come on without the nozzle or hose attached. Inspect the hose to see if that part may be broken or not making good contact to activate the switch,

The brushroll is held onto that baseplate by the metal brackets on either end of it. You have to slightly bend them outward to remove the brushroll.

It may have something caught in the roller mechanism if not the belt that drives the roller may have broken or slipped off. If the problem is neither of these then the motor that drives the belt to drive the roller may have failed, Please take to an authorized service centre and have it repaired or replaced if it does not cost more than a new vacuum if it is going to cost more than a new vacuum then discard that machine and purchase a new one. I hope this helps.

Most likely the belt needs replaced. See the Changing the Belt clip on the following site.

The Heritage II Legend...First you make sure that the machine is unplugged from any outlet,. Now, raise your height adjust to the highest level. Next you will need to turn your belt lifter on the front of the nozzel to the right as far as you can. Now flip the hinged light cover up, and turn the latch that holds down the head to the left. Your nozzle is now released. Now take the hose and roll it on to the bar from the front to the back, make sure it is aligned and then turn the latch to the right locking the hose, and you are ready to kirby it up! Hope this fixesya! Let me know, Thanks, Rene (the Vacuum Doctor)

the power light is a 2 stepswitch make sure when u put yhe power head back on it is locking all the way back if so and not working the switch may have failed

remove power head turn knob on front counter clockwise look in hole on back of powerhead make sure belt is on the hook install powerhead back on motor turn knob clockwise

there are screws on the ends. I got it fixed.

Just got done fixing our Heritage II model 2HD, it had a dirty safety switch. Both the hose attachment and the roller housing depress a plunger to close the switch, thus sending AC to the motor brushes. You might want to try pushing this in and out repeatedly with your thumb, power removed of course, in an attempt to make better contact. If this works to restore power to the motor, it'll be just a short time before the problem repeats itself. You'll have to remove the switch to give it a thorough cleaning. I didn't have any contact cleaner handy, so I wound up using WD40. Hope this helps. Kevin H.

Here is a online guide....it's for the G series Kirbys. They're similar enough that it should help. Pay special attention to the belt lifting process...it's exactly the same as for the Heritage II, and it's also where I think your problem lies. I have a Heritage II manual available too! Hope I have helped...
