Electrolux 5000 light is on where it normally says chande out bag. vacuum still will not run with hose on. with hose off works fine.

I'm assuming this is the Epic 6500 or similar model.
Detach the hose, turn vacuum on. If it runs, place palm of hand against inport hole. If it shuts off the problem is with either the control valve setting or the control valve assembly itself.
For cvs, turn dial on top of vacuum all the way to the largest dot, and try above test again. If that doesn't work, then it's the CVA. It needs to be cleaned or replaced, which is an in shop job. Fro repair, take it to the nearest Aerus Electrolux store. I recommend a full clean and service to remove any dust/dirt from the motor, fan assembly, and other internal parts.

Another problem, which relates to the dial setting, is that fine dust will quickly clog the pores of the bag, resulting in the machine "thinking" the bag is full. Turning the dial to the proper setting helps get the bag fuller. The middle setting is the normal setting, and is for areas without fine dust and sand.

i have 2, 1powers up and all 3 lights flash change hoses from the good one that work fine and it still wont run and the three blue lights continue to flash and wont run

It sounds like the valve assembly (full bag control) is faulty. Threr are two O rings inside of it and the plactic holding the bottom one has broken. You'll have to take it to the shop.

try to go with a smaller size bag

there is a clog somewhere in your hose, wand or head
a plummer snake will get it or even a broom handle

I'm not sure if I understand your problem completely, but if it is your full bag indicator that is coming on, even with a new bag, it's probably your control valve. These can be replaced by your dealer. When working correctly, the control valve should trigger the off switch when the differential pressure gets too great between the front of the bag housing and the area behind the bag. When it goes bad, it will indicate that you need to change your bag, even when you don't. Good Luck!!

Mine is doing the same thing, well it was. I sat it upright and it seems to be working fine... there is no blockage in the hose, the bag is clean... only thing I can't change is the filter. Maybe that is the problem, it doesn't seem really dirty though. I'm thinking perhaps the unit was too hot, hence having to be turned up right... makes it a little harder to move around but it is running at that is all I care. Hope this helps

Either there is something wrong with your switch. Which it doesnt sound like it. Take it to your dealer or call another one it sounds like the control valve needs to be replaced. I am a dealer 1-866-966-9350.

check the hose by putting a penny in one end and see if it comes out the other, you might have a possible clog, lux canisters are designed with a fail safe

Hi,

You have a blockage in the hose,
Use broom handle or cane to remove it.
