Samsung Dishwasher Quick Light Flashing

This is great for those moments where the dishwasher may be an unwanted background noise or there isnât enough time to get the load done by hand while completing other tasks, but what does it mean if the quick light is flashing?
If the quick light is flashing on your Samsung dishwasher, this is an indication that the water pressure is not sufficient or that the temperature of the water is wrong. Check that ample pressure is being given to the appliance and that the water heater is turned to an appropriate temperature.
As previously noted, the water pressure is likely something that you can easily remedy by turning off any appliances, such as the washer, that are using water at the same time the dishwasher is being run. If your water pressure is not great to begin with, the use of a sink tap can be enough to take away the pressure the appliance needs, causing this light to blink until pressure is restored.
