Issue: The Dishwasher Doesn’t Fill


  1. Occasionally, there can be a simple solution if the dishwasher is not filling properly. It could be that the hot water supply valve is turned off. Make sure that it is fully opened by turning it counterclockwise. If your dishwasher sees frequent use, there is no reason that the valve should be turned off. This typically happens when a new dishwasher has been installed.
  2. For out next step, you are going to need to locate the “float” inside the dishwasher. Only do this when the dishwasher is cool, at least, an hour after running it. The float is a small plastic cylinder/dome located inside the dishwasher. When you located it, life it out and clean around the float tube. Some floats must be disconnected from below. To do this, you will have to remove the lower access panel. When you are done, replace the float.
  3. If the dishwasher is still not filling, you may need to clean/unblock the screen connected to the water intake valve. This willbe located behind the dishwasher’s bottom front panel. By disassembling the valve, you will reveal the screen. If the screen is not blocked or dirty, there may be another issue. If this is the case, it is time to call a qualified service professional.
