Causes and Solutions for Dishwasher Not Dissolving Soap or Detergent Problem

Dishwashers function in a specific way. Each component in the machine has a specific task to perform.

Low Water Temperature

When the water is not hot enough, then this issue is likely to happen. The average temperature should be between 120-160 degrees F.

You can check the temperature of the water with the help of the built-in thermostat. Or you can use a thermometer to check it manually.

When the dishwasher doesn’t get the required amount of water, it cannot dissolve the soap properly.

To check if the dishwasher is getting water or not, run the machine and wait for a few minutes. Then open the dishwasher and check if it has enough water or not.

Circulation pump is responsible for spraying water into the dishwasher.

To check if the circulation pump is working fine, run the dishwasher and wait for a few minutes. Then open the door of the dishwasher and check if the water is splashing or not.

If the door is prevented from being opened, then you need to look at the cause of it. It might be an object that could be blocking the door. Make sure to look for such objects.

Jammed or Broken Spray Arm

Also, make sure that you must put soap according to its need. Putting too much for a light amount of work, can result in the soap not being dissolved properly.
