How do I turn on an lg direct drive dishwasher?

Other have noted it. There could be a number of reasons.

First things first, safety is always first so put on gloves, eye protection, etc. but most importantly turnoff the breaker that supplies power to the dishwasher, you'll find this in your home's main breaker box/fuse panel. Verify it's off by attempting to power the dishwasher on after turning off power at the breaker! Now, remove it from underneath your countertop or wherever it is, carefully unhook all electrical connections and hoses, swap out the pump, it's simple, accessing it is more troublesome than actually doing it!

I believe the time displays based on your selection. If you don't see any change when changing selection it may be a faulty touch panel.
Assuming you tried resetting the whole unit. Sounds like program error in the main board.

When you open the door, it should be on the right side of the door.

just turn power off and back on hit start it will drain first b4 new cycle starts

Have you checked whether the filter screen under the bottom panel is not clogged with food and debris?

Hi there,

An F1 usually means a communication error between the control board/touchpad and the motor/pump assy. Could you please supply the full model # for your unit?

The packets usually have detergent and rinse aid together, built in. If you also have liquid rinse aid in the automatic dispenser, you are getting a double dose, and that is causing the film. Use standard dishwasher detergent until the automatic rinse aid dispenser is empty, or at least turn the pointer indicator (located by the rinse agent filler) to the lowest setting possible to help somewhat.
