Troubleshooting Dishwasher Problems
A number of common problems with dishwashers can easily be fixed with some basic troubleshooting dishwasher strategies which do not require any technical skills or knowledge. Before you grab the phone to call a technician, identify the problem and go through the following quick solutions.
Dishwasher Doesn’t Work or the Program Doesn’t start
Check if the plug is in securely; make sure there are no signs of burns on the wiring, that the circuit breaker has not tripped, and that the outlet is in order. If the dishwasher power switch is on but the program does not start, check the door latch. It should close properly so that the door switch is pressed and you need to hear the latch click. Adjust the latch with a screwdriver if necessary. Inspect the timer or programmer switch for faults and test if the water supply valves are turned on fully.
Dishwasher Doesn’t Fill with Water
Check whether the water supply valve is turned and examine the hose for kinks. A clogged float can also be the cause. Switch off the dishwasher and unplug it. Open the dishwasher and locate the float on the base. Take it out, clean any clogs and wash the float. Reposition it and test whether it moves freely. During washing, the float needs to move freely so that it can trigger the float switch to cut off the water when the dishwasher is full. If the problem is the opposite and the dishwasher doesn’t drain, check the drain hose for kinks.
Dishes Are Not Completely Clean after a Program
Although the reason for inadequately washed dishes can be any number of things, it is surprising how often it is not a technical problem but inappropriate use. Check if the dishes are properly stacked. If the water sprays cannot reach them, you might end up with one side clean and one not. Clean the filters and make sure there is enough salt in the salt container. Switch off the washing machine and open it. Rotate the water spray arms and make sure they move freely. Check that the program you have selected is appropriate for the degree the dishes are soiled. Finally, check whether the detergent is suitable and that you are using the correct amount as stated by the detergent manufacturer. A rather mundane cause that you should also rule out is whether the dishes are not stacked in a way that obstructs the detergent cup from opening.
Make sure you are using the right amount of detergent. If necessary, use a little less next time. Switch off the dishwasher and unplug it. Inspect upper and bottom spray arms for splits and rotate them to check if they move freely. They can be removed and cleaned in warm water if required. Remove the panel at the bottom of the machine and inspect the water hose for kinks. It should connect tightly to the water inlet valve. In addition, if the machine is not properly leveled, this might be the source of the problem. Level it by adjusting the feet on its bottom using pliers or a wrench. Check whether the door switch is not pressed constantly even when the door latch has not closed tightly. Use a pencil to depress the door switch.
