Just like all other appliances in your home, your dishwasher needs a power supply for it to run. If you notice that your dishwasher is not starting, there is a possibility that you’ve not plugged it well. Also, damaged wiring can be the cause of the machine not starting.

Another common problem that makes dishwashers not to start is a defective door latch or the switch at the door latch. A dishwasher cannot start until you’ve closed the door properly. That’s why any problem with the door will make the wash cycle not to start. If you notice that there is no problem with the power connection or the dishwasher’s door, then there’s a serious problem with the electrical system of the unit.

For your dishwasher to operate at the desired efficiency, it must have a steady supply of water. However, it’s not strange to see a dishwasher that doesn’t fill with water or one that won’t stop filling. Mostly, a faulty water inlet valve causes this issue. If the water inlet valve is malfunctioning, it will not supply the dishwasher with water as required. Also, a stuck open inlet valve won’t stop filling your dishwasher—even after it has the recommended amount of water.

Moreover, issues with the machine’s float or the float switch can lead to this issue. These are important components that inform you if the appliance has the recommended amount of water. Waste or debris in the dishwasher can make the components to malfunction.

Almost every dishwasher makes some sort of noise—not unless it’s an ultra-quiet machine. However, if you notice that your appliance is making some funny noises, there might be an issue with the machine.
At times, a faulty pump can be the root cause of this problem. Also, the bearing ring or wash arm seal may be worn out, and it needs replacement. Moreover, if the spray arms are not turning well, then they might be coming into contact with the dishes. If that’s the case, let an expert from replace them.

This can prevent it from opening as it’s supposed to once you turn on the washer.

Dishes are not drying well

The heating element in your dishwasher is the probable culprit of this issue. You can check the heating element with a multi-meter to make sure that it’s functioning normally. Moreover, don’t forget to inspect the high-limit thermostat using a multi-meter to see if it’s functioning
