I'm renovating my kitchen. The old wire to the dishwasher came up from a hole in the floor and was stapled to the floor behind the base cabinets. If course I removed it then ran wire from an outlet 4' off the floor straight down to an electrical box I put in behind the dishwasher. Now I have all this wire coming out of the electrical box ready to connect to the box on the dishwasher front bottom. Should there be some type of cover on the box inside of the wall like with a hole in it or do I just have the wire coming out of the open box then on the floor under the dishwasher.

If I understand what you did, it sounds like you ran a wire from one of the countertop outlet boxes down to the dishwasher. If that outlet is one of your two small appliance branch circuits, the dishwasher should not be connected on that circuit.

You did not need a box in the wall if you were not going to make a splice. I would use a piece if liguidtite coming out of the box. That will give the wires some protection from moving the appliance in and out. Using this method you will want to put a cover on the box, since there will now be a slice in the box. They way you have, no, a cover is not required, and would be difficult to put on one with the way you have done this.

The DW should be a dedicated circuit.

I normally install a GFCI receptacle on the wall. Then use a heavy duty cord with a plug on it wired to the DW. When you need to work on or replace, pull out, unplug do what you need to.

The way I now connect dishwashers and other appliances next to an accessible cabinet is to put a receptacle in the adjacent cabinet then install a cord on the appliance to plug into it. This gives you a convenient way to disconnect if need be.

A receptacle behind the dishwasher should not be a GFCI as it is not readily accessable to reset if need be.

So what was wrong with the first wire you had?

My understanding it is illegal to have wires stapled to the floor? They need to be enclosed inside tubing or in the wall otherwise it needs to be armored?

Besides, mice ate the wire in the walls in the garage and it's winter and I'm not ready to clean the garage and track the wire. Wife needs a dishwasher now thus running the wire from a above the countertop outlet down. With new cabinets in, sheetrock walls, tile backsplash, no one will know.

Why does a dishwasher require a dedicated service?

I can understand a refrigerator requiring a dedicated line.

To secure the wire, I used a wire clamp through a hole in a blank cover.

The manufacturer's instructions call for a dedicated circuit. Also the code says the countertop circuit shall not serve other areas or fixed in place appliances.

Good point, I put them behind the sink base cabinet with a access hole.

Dishwashers contain heating elements to heat the water to a temperature above the incoming hot water temperature. The heating element is also used to dry the dishes when the cycle completes. Many dishwashers can draw 12A at 120V. That's why they should be on a dedicated circuit.
