I'm a plumbing contractor that is in the process of figuring out what kind of water heater I need to supply hot water to a #AM15-1 dishwasher. Will this dishwasher work off of 140 degree water, or does it have to have a booster heater to boost the temperature to 180?

The unit should be hooked up to the hot side of the supply. A lot of dishwashers have heaters, but using hot water saves them the time to heat the water to the prescribed temperature, around 140 degrees.

a dishwaher needs hot water to work properly a mixer i believe works so you do not get burned by hot water i believe correct me if i am wrong with a normal tap all you need is a special fitting for your portable and they usually are supplied with a new one or are cheap to purchase from a plumbing supply or loewes or home depot.check with where you want to purchase washer and ask if they work with a tap mixer
Generally speaking, dishwashers don't heat cold water on their own. Be sure the dishwasher is connected to a hot water supply and that hot water is available to the dishwasher at the START of the cycle.
Often it takes hot water several seconds for house plumbing to deliver hot water to an outlet. If the dishwasher is connected to the kitchen hot water supply, run the water in the sink until the water runs hot before you start the dishwasher.
Dishwashers often have heaters to heat the water even hotter than most home water heaters, but they are not intended to heat cool or cold water. You MUST furnish hot water to the dishwasher from the time the cycle is started.
I've seen houses that take so long for hot water to reach a faucet, the dishwasher is already full (of cold water) before the first drop of hot water reaches it.
If this dishwasher is a residential dishwasher the water that is supplied to the unit is from the hot water side of the sink supply. The dishwasher does not heat the water it uses water from the water heater that is connected to the house. It sounds as if the dishwasher is hooked up to the cold water supply instead of the hot water supply. The heating element you see in the dishwasher is for drying purposes and not for heating water. I would check the hot water supply for your dishwasher to see if that could be the problem. Also remember unless you have a recirculating pump on the hot water there will be an amount of water in the pipe from the water heater and the dishwasher that has sat and cooled down over a period of time therefore when you turn on the dishwasher you will not get hot water immediately due to the distance the dishwasher is from the water heater. You will notice when you turn on the hot water to thew sink you do not get hot water right away you let it run for a minute before it gets hot since the dishwasher is connected to the same valve as your hot water to the sink it acts the same way.
Good luck on your repairs hope this helped.
sounds as if the water supplied to your dishwater is on the cold side supply. Dish washers do not heat water themselves they have the hot water supplied to them from the hot side of the water supply to the house. Very few dishwashers have a water heater hook up built into them.. I would check the water supply to the dishwasher I think there is where your trouble is. Good Luck
Do you have it hooked up to hot or cold water supply? Most residential dishwashers don't come equipped with a booster heater. If it's connected to the cold side, you'll have to replace the angle stop with a single outlet stop and replace the hot angle stop with a double outlet stop. This should help out, if not, make sure you have hot water in the faucet before starting the dishwasher. Most dishwashers need at least 120 degree hot water supply.
