Your best bet is to give Leviton a call to help them troubleshoot it. The challenge is that I can think of a number of reasons why this may happen.

1) Electrical power issues - some lighting control products can respond poorly to electrical noise (if you turn on a hair dryer or motor, sometimes the electrical noise it generates can travel through the power wires and effect the dimmer's performance). I actually kind of doubt its the case because if the device shuts off and STAYS off, usually the dimmer's power failure memory would kick it back into gear, and it sounds like its not doing that, so...

2) Loose connection in the back. Some of those dimmers have an addition wire (or screw) attached to them to provide multi-location dimming. If that wire/screw is touching another connector (or a grounded backbox), it can fool the dimmer into thinking its supposed to do something (like turn off).

3) Touch panel environmental issues. Some of their digital dimmers are 'touch' dimmers, and they can be impacted by the environment. There are several ways in which the devices work, but generally speaking, when you hit "a button," you are either affecting the enviornment around the dimmer or the dimmer leaks current through your body, and the dimmer uses that change in its environment to detect the button press. Regardless, if this is an a high-humidity area, or if its near an air-condition, or possibly heater, fan, something like that - its possible that something is "fooling" it.

But again, these are all guesses. I would call their tech support center for sure.

    I had a problem with my lights going ON by themselves. Called Leviton, it is due to body oil accumulation on the switch faces (not filth mind you, just oil you can't really see). It fools it into thinking it is being touched. I remembered cleaning it with Clorox Cleanup days before this started after they said that. I cleaned them off with a damp paper towel with a tiny bit of dish detergent on it then they did some odd things for about 5 minutes until they dried and then were fine. Weird, I know.

I am replacing a Lightolier 3-way Dimmer switch with a Leviton IPI06-1LX Dimmer switch. When I install the dimmer switch it works fine. But the on/off regular wall switch won't turn the light on or...

It depends. Some dimmers are considered "smart dimmers," where the control on the other end of the 3-way has to be intelligent enough to send a signal back to the dimmer. If the Lightolier dimmer was a smart dimmer, then chances are that the 3-way control was designed to talk only to that specific dimmer. The Leviton product you replaced it with is a simple, basic dimmer - it should work in conjunction with a simple, basic 3-way switch.

If the 3-way control already IS a simple, basic 3-way switch - then I would simply re-check the wiring of the dimmer you replaced.

The other switch should only be changing from one wire being hot when it is in the up position to a second wire being hot when it is in the down position. Then the new dimmer should be hot on one terminal when the other switch is up and on a different terminal when it is down.
I'm not sure how the Leviton dimmer works, though.

My rotary dimmer doesn't switch 3-ways. I have to push the dimmer button to "on", then I can use the other switch to turn on/off.

You posted under Leviton rotary dimmer.
Lutron and Leviton have many 3-way dimmer styles, and both make 3-way rotary dimmers.

I remember years ago replacing 3-way switches with dimmers and having same experience as you. One dimmer has to be ON for the other dimmer to dim.

Later I learned when you replace both 3-way switches with dimmers, you buy a control-and-companion dimmer set. One dimmer is main, and it lets you dim from both locations. The two dimmers communicate with each other electronically. Buy these dimmers at lighting store that specializes in fixtures and dimmers. Ask for most experienced salesperson.

I checked to see if rotary dimmers are made in the companion set. And neither Leviton or Lutron show 3-way companion set rotary dimmers.

1) Leviton spec sheet on rotary 3-way dimmers does not show companion dimmer. This indicates that Leviton rotary dimmers don't have capability of communicating with each other.

2) Lutron has image of 3-way rotary dimmers.
Image shows single rotary dimmer in 3-way & 4-way circuit.
This tells me that Lutron does not have companion dimmer for 3-way rotary dimmer.

The dimmer switch will turn on and off but wont dim the lights on a chandelier. model 6681-w. tried 2 different ones with the same results.

The Leviton 6681 is a push-button rotary-type incandescent dimmer with 600Watt capacity
If you have incandescent bulbs, the dimmer should work.
If the dimmer has different color wires, try reversing the wires.
If the dimmer replaced a 3-way switch, then this is not the right dimmer.
If you have compact florescent bulbs, you need a dimmer that also dims florescent.
Link shows the Leviton 6673 incandescent and florescent dimmer

But you also need dimmable compact florescent bulbs.

I am trying to replace a two wire light switch(both white) with a leviton photoelectric 3 wire motion activated light control(red, black and green). I am trying to determine which wire goes to which?

one of the white wires has power on it constantly....that wire connects to the black wire of the leviton.......the other white wire which has no power to it is going to whatever needs power so that wire connects to the red wire of the leviton....the green wire connects to the metal box where your mounting the leviton.

Light dimmer issue

the light on the switch does not men it is wired correctly, it only means that you have supplied power at that point. Without knowing more its hard to say, but I'll assume this is a single switch operating a single unit. That being the case, and depending on your fixture, occassionally wires must be grouped together on the switch side. Also quite often these switches are simply defective, and must be returned. If you think you have it correct then its probably a bad switch.
