What Causes Dishwasher Soap Not Dissolving Problem

To understand this issue, you have first to know how your dishwasher works.

The dishwasher works the same way you wash your dishes using your hands. Typically you will apply soap and do a little scrubbing and then wash it with hot water to remove all dirt.

In the same way, the dishwasher works. But it is automatic and its a machine, which means it can work continuously. When you start the wash cycle, the dishwasher will start working from this point. It will also dry the dishes if you have a dryer option.

Water temperature is not hot enough

The water temperature inside the dishwasher should be above 110F/115F. Anything less than that, then the water will not be hot enough to dissolve the soap/detergents.

Many dishwashers come with a built-in thermostat that tells you water temperature. If your dishwasher does not have a built-in thermostat, you can also check the temperature using a thermometer.

To avoid it, you can run the water in the sink till it is sufficiently hot, and after this, start the dishwasher. We recommend running the dishwasher in the longest and hottest mode.

How does Dishwasher work?

Instead of using hands, the dishwasher uses high-pressure water jets from the washer arms’ tiny holes to scrub the dishes. The dishwasher also has an arm that rotates around the rack in which dishes are there. It makes sure that each plate gets properly cleaned.

The ideal temperature of the water that comes from the spray arm should be 120-160ºF. The hot water can dissolve the soap easily that helps in cleaning the dishes efficiently.

A dispenser door is where the soap/tablet is dropped into the hot water for washing. It will dissolve into the hot water.

This soapy water will then pump out from rotating arms in the form of water jets, which do all the cleaning stuff. Finally, the dishwasher drains out all the water after the wash cycle.
