Kenmore dishwashers have control panels with a series of lights that indicate what part of the cycle the machine is in. These lights may also blink when there is an error to notify you that a problem has occurred. If the “Normal” light is blinking, several possible problems could be happening and would require some troubleshooting to find the exact cause of the blinking light.
Before checking for possible problems, make sure the water supply is on if your Kenmore was recently installed. The water valve should always be turned on when the dishwasher is connected to it. You should also make sure the water hose is firmly connected and the hose is straight with no kinks. You want there to be no obstruction so the water will flow freely.
Overfill Protection Float
The problem may be caused by an obstruction that prevents the water from being able to enter the dishwasher. If this is the case, the overfill protection float is probably stuck. The float is located on the bottom portion of the dishwasher and is shaped like a little plastic cone. When working properly, the float moves up and down to stop the dishwasher from overflowing during the wash cycle. Tap the float with your finger to see if it is caught in its current position. Slide it up and down to see if it is working properly. Press down on the top of the float to release it if it appears stuck in place.
The problem could be too many soap suds in the tub of the dishwasher. If this happens, it causes a drainage problem. This typically happens a detergent is used that isn't meant for the dishwasher, such as liquid hand or dish soap or laundry soap. When the unit recognizes too many suds in the tub, the “Normal” light will blink to indicate an error. To fix this problem, add a gallon of water to the tub and start a drain cycle.
The “Normal” light should stop blinking automatically once the problem has been fixed. However, if it doesn’t, you should call the Kenmore customer service line to schedule service for your dishwasher. The number is found inside your instruction manual.
