My electrolux SB915WJ dishwasher doesn't heat water anymore. Ican't find any details on this model.

Error code C13 on an Electrolux dishwasher model EHT8ILG8 indicates a problem with the water supply to the dishwasher. The code specifically refers to a problem with the water pressure, which could be caused by a clogged water inlet filter, a malfunctioning water inlet valve, or a problem with the water supply hose.
To troubleshoot this issue, first check the water supply hose to ensure that it is not kinked or clogged. Then, clean the water inlet filter and make sure that the water supply to the dishwasher is not restricted in any way. If the problem persists, it may be necessary to call a professional technician to diagnose and repair the dishwasher.
Please keep in mind that this is based on general information, the error code meaning may vary depending on the model and brand. It's recommended to check the dishwasher manual or contact the manufacturer's customer service for more specific information.

Hello Kevin, thank you for your post!
From my understanding your Electrolux dishwasher is not fully dissolving the detergent tablet. It may not be an issue with the water heating up it could be a possible problem with the water not receiving adequate pressure or not enough water. Does your dispenser have any build up inside of it? Have your spray arms been recently cleaned? I would recommend cleaning the dispenser and spray arms out. I can also provide you with information regarding any heater inside of your dishwasher. In order to do so I need your model number. You can locate your model number on the inside wall of your dishwasher. With this information I would be happy to assist you further. -Matt

what is the model number to your dishwasher? Geraldine

If your Ohms are at "0" then the heater is open.

it,ll be the circuit board definately come across this problem alot.

it can be the element is cheap enough but 9 times outta ten it,ll be a circuit board fault which can be exspensive.

This model does have an inline heater to heat the water to the proper temperature, but it does take a long time and you are recommended to run the tab on the faucet from which the dishwasher water line is tapped from. This clears all the cold water from the line

tHERE IS A HIGH TEMPERATURE CUT OFF SWITCH WHICH LOOKS LIKE THE BAK OF A STAINLESS STEEL WATCH IT HAS TWO LUGS THAT THE HEATER ELEMENT IS ATTACHED TO. IF YOU TEST IT YOU WILL FIND THAT IS IS OPEN CERCUIT. I'M NOT SURE WHERE IT IS ON THAT MODEL BUT IF YOU HAVE MANAGED TO TEST THE ELEMENT YOU CLEARLY HAVE THE THING TO BITS.

You have to test the heating element with an ohm-meter. It should read very low ohms. If the element seems ok, you have to test the controller to see if it is powering the element (probably should be 120 volts)

before you operate the dishwasher get your water as hot at the sink as you can this will prevent filling the dish washer with cold water and i would use powder or liquid now if you not sure of your heating element turn your washer to dry close the door for about 2-3 minutes get a glass of cold water open the door and pour water on the element if it sizzles its working
