[TedElectro59]

I have an Electrolux EPIC 6000 doesn't run , the ? light flashes ?
I don't have a hose for it , is that why ?
What could be the problem ?

im not an expert on these newer Electrolux machines, but im pretty sure it won’t start if there’s no bag. Ones fitted right? This might help,

be better with a hose yes but hsould run with a bag in it as mentioned try that if it still wont go might be the sensor gone bad
