My dishwasher has always washed in cold water never had any hot water why is that

Some dishwashers can run for 4 hours or more normally depending on the options you choose. What do you mean by it runs through cycles is it always changing cycles by itself or is it just the cycle you pick just keeps on going, have you tried a quick wash or 1 hour wash does it do it then? is you hot water hot enough? if not it makes the unit run longer because it has to heat the water up. always run the hot water at the sink to bring hot water up from the water heater to the sing so the dishwasher fills with hot water and not cold.

Always to the HOT WATER supply... If you want a proper dish-washing; you can connect it to the COLD WATER supply but in the end your dishes will look just a little bit less dirty than when you have inserted them into the slots...

No, you do want to make sure that your water heater is set to 125 to get the best wash

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.

the supply to the d/w should be at least 120degrees.the p2 error is a bad booster probe. always use hot water feed

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.

Good luck. Hope this helps.

most diswashers only hook from the left side under the sink which is hot, some dishwashers on hot make the water extra hot with the bottom element for pots and pans, sounds like your dishwasher is working properly, you need hot water to sterilize. Rob

has it always been connected to cold water??? cant see how that would getanything clean designe dfor how water.

It is very common that high eficiency, low water using dishwashers take longer to finish all cycles. The best way to "hurry" the washing is to make sure that the water heater is providing hot water of at least 120 degrees. But no hotter then 140 degrees.
If the dishwasher runs even longer, check to see is the dishwasher is actually connected to the cold water line. This dishwasher can be run from cold water but the water heating phase in the cycles will add much time ti the entire cycle.

This unit has a sensor that detects the detects the water clarity towards the end of the wash cycle. Rinsing the dishes may speed the load a little, but encourage not to go crazy on the rinsing because the dishwasher actually counts on the food particles to help clean the dishes.
Also, note that the final (third) blinking light means drying. You can simply open the door anytime after the final draining and power off the dishwasher, allowing the hot dishes to air dry.
Hope this helps. Please resply with your findings. Thanks!

Dishwashers are suppose to be hooked up to hot water. If you had hotter water it would clean just fine. 120 deg or more!
