dishwasher installation/wireing

I plan on installing a built in dishwasher it will be on the right of the sink and the outlet is on the left above the counter so i have to add another outlet do I need to take any special precautions?does the wire gauge change?

You are not allowed by code to connect the dishwasher to a circuit serving a kitchen counter receptacle.

Was this house ever wired for a dishwasher? Or perhaps for a garbage disposal? If so, you can tap into either of those circuits. If not, you should install a new circuit. Some dishwashers require a 20-amp circuit, some can run on a 15-amp circuit. If you have both the disposal and dishwasher on the same circuit (not the best idea, but workable), then it should be a 20-amp circuit.

Wire gauge always matters. Use either 12 or 14 on a 15-amp circuit, and use 12 only on a 20-amp circuit. It's a good idea to use 12 on both.

The water heater circuit is not going to satisfy this need. Almost all water heaters are 240-volt, and almost all dishwashers are 120-volt. Furthermore, the water heater circuit was sized for the water heater alone.

You're going to need a new circuit for your dishwasher.

The two most common things in a house to run off a 30-amp 240-volt circuit are an electric water heater and an electric clothes dryer. 30-amp 120-volt circuits are not common.

I commend you for doing the research to identify exactly what is controlled by what breaker. This will come in useful over and over again.
