You also may want to check the.....
Gary,
You said it comes on after pushing it back and forth a few times, then once it (does) come on it flickers on and off?
Hmmn. Well Fred is quite right about checking the bulb and if it's seated properly ( they have and do get misadjusted). I would just twist the bulb between your thumb and forefinger to make sure it's right you can go either clockwise, or counterclockwise. You can actually feel when it's right on. There is a definite "Stop" when it's right. , and if your facing the rear of the powernozzle, (with the cover off of it), you should also see over on the right hand side towards the corner a small silver "starter". Make sure that has not come loose, as it has happened to powerheads in years past.
If that doesn't correct it, you will need to undo the rest of the nozzle, and personally I wouldn't do that myself if I was not sure of my abilities. It's not pleasant to go any further without a manual, or some experience to go by.
If you wish to contuinue, beneath the plastic cover, you will find the rest of the wiring, which will need to be checked for proper connection, and continuity. I would have a digital "multi-meter" to check for proper continuity between the wires and the junctions.
Taking apart this powernozzle is not fun. It's possibly the most difficult one out on the market. It's not un-doable, but I'm just giveing you a STRONG fairwarning, that you either will give up, and take it to your Miele dealer, curse and swear like you've never before until you get it right, or worse you will break it further.
All of these things have happened in just the last year alone to me here at my store. Becasue customers were trying to save a buck...and fix it themselves.
And you have a Cparicorn? You have a bumper to bumper one year warranty... Just take it in and let someone do it. Why tear out your own hair, when that's unescesary. If it happens to be out of warranty contact Miele directly, and stomp your foot. Many times they will to kepp the peace...help you and maybe pay for parts, and you...just have to foot the labor.
Hey it's that or worse a whole new nozzle @ $250.00
I'm not wanting to scare you, just letting you know that this shouldbe fully thought out before you go "into the valley". If you do i will help you if I can.
You can e-mail me directly if you;'d like.
