Most likely the hot water temperature is the problem. If you have a separate hot water inlet check that the water temperature is ok. But if you only have a single cold water inlet then the heater inside dishwasher may be faulty. Check if the dishwasher is still cold when you terminate the cycle.
Heater is part 13 in this diagram.
Dishwasher must be connected to a hot water line in order to work properly. Also, it often requires a good deal of time for hot water to make its way from the water heater to the dishwasher. If the dishwasher is located under the kitchen counter, turn on the hot water in the sink until it runs hot, then start the dishwasher.
Many dishwashers have a built in heater, but hot water should be initially fed into the dishwasher through the water inlet in order for it to perform properly.
You are supposed to connect the dishwasher to the HOT water side. Although most dishwashers have a heating element to heat the water, they are normally installed this way to reduce the amount of time the heating element is on. This not only extends the life of the heating element, but also reduces the amount of electricity required to heat the water.
Another helpful hint: Before you run the dishwasher, run the hot water tap until the water runs hot. This will fill the dishwasher with water that is already hot instead of the cold water that normally sits in the line after the hot water has been shut off for a while. If you have questions, please let me know. I hope this helps you.

Try turning on the faucet by the dishwasher and let the water run until it gets hot. Once this is done turn on the dishwasher and see if the water is warm or hot. Most dishwashers do not heat the water (residential dishwasher) they take the hot water from the hot water side of the sink. If the water heater is located a distance from the dishwasher then the cold water fills the dishwasher before the hot water can make it to the unit. This should cure your problem.
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.
HI Nick- the element in the dishwasher dries the dishes and sometimes boosts the heat of the water. Your water should come in already hot, so the problem is either your hot water heater or that the plumbing line was switched to cold by mistake. Or that people are bathing, laundering, etc. and using all available hot water right before you run the dishwasher.
Dishwashers normally are hot or cold feed. My wife runs water at the sink to get it hot going in before turning on the dishwasher. You can use either cold or hot water. We have ours hooked up to the hot water side. They work better hooked up to the hot water.
