Dishwashers are quite essential to any large household, nowadays. They save not only your time but quite literally, your hands as well. Gone are the days of washing dishes and scrubbing pans until your hands are sore and it’s way past your bedtime.
Or are they?
Like all machines, dishwashers can experience faults, too. One of the most common ones is when the dishwasher stops heating properly. The indicators of this are usually something of the sort:
As you might have guessed by now, there is no quick solution to this problem. There are, however, several probable causes which you can try and troubleshoot yourself. With that being said, let’s start with the first…
The first and most obvious part to check is the heating element at the bottom of the dishwasher tub. You will need a digital or analogue multimeter to test the electrical resistance of the element. The multimeter will help you avoid any guesswork whether the heating element is indeed faulty or not.
You don’t need to uninstall the dishwasher for this procedure, however, you will need to do some crouching. But first, set your multimeter to the lowest setting of ohms of resistance. If you have a digital device, you’re ready to check the electricity. For analogue multimeters, touch the probes together and adjust the needle until it’s at 0. Now you’re good to go.
To replace the heating element of your dishwasher, you will need to uninstall it first. Take photos of all the parts before you disassemble them. Prepare a blanket to lay the dishwasher on, once you take it out of the cabinet.

This device regulates the temperature of the water used on your dishes. Even if your washer has a hot water connection, the thermostat still plays a significant role in getting the water hot enough for washing. The thermostat also regulates the temperature of the hot air used for drying your dishes. And, like all other electrical components, this one can falter, too. If it so happens that your heating element is okay, then check the thermostat. Unfortunately, you will have to uninstall your dishwasher first.
Now you can check the thermostat for electrical continuity with your multimeter. If it shows 0, it’s okay, if it’s way above it, it’s faulty. Fortunately, if you need to change the thermostat this is the right time to do so. All you need to do is place the new one in the bracket and follow the steps mentioned above, only in backward order.
This piece of tech is the brain of your dishwasher. It controls all the functions from the initial filling of the water chamber to the drying cycle at the end of it all. Malfunctions of the control board present themselves in different ways and your dishwasher not heating may be one of them.
