Dishwasher not heating up the water. Dishwashers need hot water to function properly, otherwise they’ll just leave your dishes dirty.
If your dishwasher isn’t heating up the water, or not heating it enough, it might be due to a number of factors.
The make and model of your dishwasher, as well as the water delivery system, can play a role in why the water isn’t getting hot enough.
With dishwasher problems, more often than not, there isn’t a “quick fix” solution that you can do on your own.
These types of problems usually require calling out a dishwasher repair engineer. However, there are some more general issues that you may be able to troubleshoot and fix without professional help.
Dishwasher Not Heating Up The Water
We will discuss here the causes of not heating the water.
Clogged the Drain Filter
Your dishwasher’s drain filter is important because it captures food, dirt, and debris particles that come off of dishes during the washing process.
If the filter becomes too dirty or blocked, the dishwasher’s suction power will be reduced. This can impact the unit’s ability to heat up.
So, if you think the drain filter is dirty or clogged, remove it from the dishwasher and soak it in warm soapy water for 30 minutes to an hour.
White vinegar is a great option for cleaning when you need something more heavy-duty.
Faulty Heating Element
If adjusting the thermostat does not produce the desired results, the heating element may be to blame.
The heating element is in charge of ensuring that the dishwashing process takes place at the proper temperature and that the dishes dry properly afterwards.
Though this part is typically built to last, an electrical fault can cause it to fail over time. A multimeter can be used to test the resistance of the heating element.
The ideal resistance reading is between 15 and 30 ohms. If the reading is higher, it means the heating element needs to be replaced.
The thermostat is a small but important component in a dishwasher. Its job is to tell the other parts of the dishwasher, like the heating element, what temperature the water should be.
If the thermostat isn’t working right, it’s no wonder that the water isn’t the right temperature. You can test a thermostat with a tool called a multimeter.
This measures the voltage, current, and resistance of a component to see if it’s within the expected range. Replacing a thermostat is usually not too expensive.
The hard part is getting access to the thermostat, which is often located under the dishwasher.
How can I tell if the heating element in my dishwasher is broken?
If your dishwasher doesn’t seem to be heating up your dishes properly, there are a few things you can check. First, make sure that the heating element is working. If it’s not, you’ll need to replace it.
If your dishwasher is connected to the hot water line, you won’t have to worry about your dishes being cold when the cycle finishes.
After you’re finished with the washing cycle, it’s a good idea to check on your dishes. The hot water can make them warm, so it’s best to make sure they’re all clean before you put them away.
Does a dishwasher use hot water to clean?
The dishwasher needs a few things to work well – soap, water pressure, and heat. All dishwashers use hot water to clean the dishes, because warm water is necessary to break down food and reduce the amount of water left behind on dishes.
If you’re having trouble with your dishwasher not getting hot enough, you should check the temperature settings and make sure they’re where they need to be.
