Try it, You'll Like It.

Your dishwasher uses your hot water to wash the dishes.
Attach your hot water to both the sink and dishwasher at that (hot water) inlet.
Run the hot water in your sink until it is very hot, then turn on your dishwasher.

You should always turn the hot water faucet at the kitchen sink first before starting dishwasher. If you don't your entire wash is cold water. This will also cause the water temp mode to take forever to heat the water to the 140 that is factory set. Hope this helps.

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.

hello. I can help you. Make sure your dishwasher is empty. Then pour two cups of vinegar into the dishwasher. Next run the hot water into your kitchen sink until it is as hot as it gets and start your machine. Run it on the longest and hottest cycle you have..

This will clean your machine. Repeat the process with more vinegar if you need to.

Once your machine is clean, be sure to always run your sink water until it is hot before turning on the dishwasher and also rinse your dishes. good luck with it.

Are you using the high wash temp setting? I was having the same problem with my dishwasher while using that setting. Apparently, it will run until the temp gets to its required number. And my hot water heater was set to not go that far. So my dishwasher would run and run. I fixed it by not using that setting any more.
