Tip & How-To about Dishwashers

Dishwasher Water Temperatures

No matter what detergent you use, the "pills", powder, or gels, they are meant to activate PROPERLY, key word PROPERLY, at a minimum of 120 degrees Fahrenheit in a dishwasher. I recommend ALWAYS using the "high temp wash, boost, etc" on ANY cycle in order to keep the water HOT! Always run the hot water in the sink prior to starting the dishwasher! The unit is tied in to the hot water line under the kitchen sink and requires very little water to fill--by the time the hot water finally reaches the dishwasher, chances are it'll be running on cold or tepid water--the detergent won't dissolve or activate the way it's supposed to. Not only that, in between fills during the cycle, especially in winter, the water will cool down in the pipes too much. Normally, the water heating selection will maintain water temps in the 130-150 degree range! If someone has been sick in the house, turn on the SANI RINSE if your unit has it! This won't stop--but it'll help prevent cross contamination--people getting sick from the dishes--this setting normally kicks the water temp up to 190 degrees during the rinse cycle.

Which detergent type is better, liquid gel or powder?


I recommend the powdered/granular detergents because sometimes the gels don't perform so good. I have found that prominent brands are better than some of the generics.

There is always detergent left in the compartment and my dishes don't seem clean. It doesn't seem to matter if I use powder or gel detergent and I don't overfill it.


I expect your filter is clogged which does not allow sufficient water to get from the pump to your spray arms. Thus they do not clean out the detergent nor do they clean the dishes. You might test this by placing a glass right side up in the top rack and run a normal wash cycle. The glass should fill at least half way with water.

Dishwasher detergent clumps in pre-wash and main wash compartments


Make certain that there are no apparent obstructions between water and detergent. If no obstructions and the detergent dispenser and spray arms are operable, then the detergent should dissolve during wash. Otherwise, try using a different kind and amount of detergent (e.g.: powder vs. gel or gel vs. powder, and less detergent). If still clumping, contact an appliance service company.
