Dishwasher Fill Cycle – Timer, Float and Water Inlet Valve

Posted by: | Comments Comments Off

Dishwasher Float

Your dishwasher fills with water on a timed cycle. What does this mean? The timer or electronic control board in your dishwasher controls the amount of water your dishwasher fills with by turning power on and off to the water inlet valve. The water pressure entering the dishwasher will determine the amount of water allowed into the dishwasher so if you have low water pressure in your home your dishwasher may not be able to fill with enough water in the allowed amount of time dictated by the timer or control board. Your dishwasher has a float that keeps the dishwasher from over filling incase you have very high water pressure or in the event that the timer would fail to turn power off to the water inlet valve.

Shown in the image is a spoon I found under the float. In this case the spoon held the float up high enough to keep the dishwasher from filling with water so it was unable to start a new cycle. If your dishwasher does not seem to start a new cycle because it won’t fill with water open the door and take a look at the float. Even if you don’t see anything stuck under the float be sure to try and lift it up and down with your hand to make sure it can move freely.

Repaired Maytag MDB7100AWB Dishwasher That Was Dead

Posted by: | Comments Comments Off

Here is a common problem I have run into a number of times in the last few months. This Maytag MDB7100AWB dishwasher was dead, just as if it was unplugged.

Sometimes I see this type of dishwasher where the lights on the control panel may work, but you can’t start the dishwasher and other times I have seen were no lights work, but you can start the dishwasher.

In all the above cases I ended up having to replace the control board, part # 99002824 to repair the dishwasher.

Frigidaire Electrolux Dishwasher Soil Sensing

Posted by: | Comments Comments Off

 

Soil sensing is performed in all wash cycles except the Rinse only cycle. Mounted on the right side of the sump, the soil sensor transmits light from a transmitter to a receiver to measure the amount of soil in the water. This information will be used by the control to determine the length of the cycle.

Once pre-wash loosens food on the dishes, the motor stops for 30 seconds. This allows the wash water and food soils to settle for the soil sensor to check the soil levels in the water.

Now that this reading is taken, the dishwasher drains the dirty water and fills again for the pre-wash rinse. Once this rinse is complete, the wash motor pauses again, a soil level measurement is again taken. The control uses these readings to adjust the wash cycle to ensure a clean load of dishes.

Video: How to Remove Whirlpool Dishwasher Food Chopper

Posted by: | Comments Comments Off

In this video I show you how to remove the food chopper in a whirlpool dishwasher so it can be cleaned or replaced. If the top arm of your dishwasher is not rotating around it could be because the food chopper screen is plugged restricting the amount of water going through the pump. If this happens sometimes you can simply clean the food chopper screen, but most of the time it’s best to replace the food chopper because the blade has been damaged.

Often times I find a noisy dishwasher also has something stuck in the food chopper. In this case simply removing the food chopper and cleaning it takes care of the noise.

Video: How to test a dishwasher heating element.

Posted by: | Comments Comments Off

This video show you how to test a dishwasher heating element with a multimeter.

Testing and replacing a bad heating element in a dishwasher is a simple repair job that any one can do.

Simply set your multimeter to ohms and check the element for continuity. If you have continuity across the element then it is good. If you do not have continuity across the heating element then it is bad and it will need to be replaced.

If you have a bad dishwasher heating element you may notice the cycles take longer to finish and the dishwasher does not get things clean like it use to.
