Dishwasher running on cold water

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.

The usual discrepancies with run times is due to water heating time.
For example, your dishwasher may be estimating run time + time to heat the water from cold.
If your dishwasher is connected to hot water instead of cold, it will skip the majority of the heat cycle and adjust the time accordingly.
On the other hand for other people, their dishwasher brands may say "50 minute wash" but this does not take into account heating time, so wash can be anything up to around 70-80 minutes.

This is an error code.

The error indicates that your dishwasher is failing to heat the water in an allotted time. The error can be caused by numerous issues but the first thing you want to do is reset the control board.

-To reset the control board press: high temp wash, heated dry, High temp wash, heated dry, high temp wash, heated dry, high temp wash, heated dry, high temp wash. If you don't have a "heated dry" button, use the "air dry" or "energy saver dry" button instead.
-All the lights will go solid at which point you press cancel to reset the board.
-If the control board doesn't reset, it's likely that you've just got a faulty control board and the control board will need to be ordered and replaced.
The next step in this process is to start a new cycle and see what happens. If the error code returns, then you'll want to reset the board again and check several things. The most common reasons for this error is because the water coming from your household is just too cold. The dishwasher is expecting 110 degree water to enter your dishwasher, so if your pipes are cold, the water may only come in luke warm. To correct this issue, just run your faucet next to the dishwasher until the water coming out is hot. On another note, make sure the dishwasher is washing with good water pressure. You can put a cup in the upper rack facing upwards and run a cycle to see if it will fill within 10 minutes of starting the cycle. If it doesn't fill with water then you know that the dishwasher isn't producing enough pressure which, in turn, will cause the water to not heat. You'd want to take your pump and motor assembly apart to clean inside if you had a loss of pressure.
You could also have a failed component including a faulty heater, control board, or high limit thermostat. You'd need to uninstall your dishwasher, disconnect power and lay it on it's back to check the resistance of the heater as well as the resistance of the high limit thermostat to confirm if they were bad or good. You should get tangible reading of between 5 and 30 ohms on the heater if it's good and less than one ohm on the high limit thermostat. If both of those devices check good, then replace the control board because that's the one device you cannot test.

the dishwasher might accept cold water but must heat the water up during the cycle. If it does not then check the heater circuit......element...thermos NTC, with a meter for electrical continuity....some dishwashers stop mid cycle if the re is no heat but some go right through on cold depending on the make.. good luck

Hi there,

Unfortunately, it seems that the heating element has failed. The dishwasher uses steam to heat the tub to dry the dishes. I suspect your dishes are also being washed in cold water.

To check this, please run a regular full wash cycle. Allow the washer to fill with water and run for about 10 minutes, then open the door and feel the water temperature in the bottom of the washer. If the water is cold, it's more than likely the heating element has failed.

There are other possible faults which would cause the element not to heat, but these often prevent the dishwasher from completing the cycle. If the water is cold but the dishwasher still drains the water at the end - and completes the cycle - the heating element has probably failed.

Please try this simple test for water temperature and let me know if you need further assistance.

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.

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.

indicates that the heating element in the unit is non operational ( not connected or burnt out )

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!

This is either a bad timer or a bad heat sensor. On most cycles that call for the water to be heated it will pause the timer and continue washing/heating until the sensor is satisfied the water is hot enough. Try selecting a quick, delicate, or china cycle without heated rinse or dry. If it works this way the timer is fine but the sensor is bad. Sometimes cold water to the machine will cause this problem because the machine is not capable of totallly heating cold water. It is only designed to boost the temp. Make sure you run hot water at the sink before you start the machine.
