Dishwasher Detergent Dispenser Not Working? How to Fix It

By Fix4U Team
Dishwasher, Kitchen Appliances

You always make sure to fill up the detergent dispenser before running your dishwasher. But when you open it after the wash cycle completes, you find the dispenser still full of detergent. A non-functioning soap dispenser fails to properly release and distribute detergent, resulting in dishes not getting fully clean.

The automatic detergent and rinse aid dispensers are essential features of your dishwasher. When something stops the dispenser from opening to release soap at the right time, it needs to be addressed. In this article, we’ll cover common causes and solutions to fix a dishwasher detergent dispenser that won’t open.

Why Your Dishwasher Soap Dispenser Won’t Open

Here are some of the most likely reasons a dishwasher detergent dispenser won’t release soap:

Clogged or Stuck Dispenser

Detergent, grime, and water deposits can clog the dispenser, keeping it from opening outward fully. Stuck latching mechanisms can also prevent the door from popping open.

Obstructed Dispenser

Large dishware like cutting boards and baking sheets placed in the bottom rack can physically block the dispenser from opening when positioned improperly.

Worn or Broken Dispenser Hinge

The small plastic hinge allows the dispenser cup to pivot and drop open when released. If worn out or cracked, the dispenser can’t swing open.

Faulty Dispenser Wiring

The electronic controls and wiring coordinate when the dispenser should activate to release detergent during cycles. Damaged wiring will lead to a dispenser not opening.

Defective Control Board

Issues with the control board can prevent it from signaling the dispenser to open and release soap at the appropriate time during the wash cycle.

Broken Actuator

There is a small bi-metal actuator that triggers the dispenser cup to pivot open when heated by incoming water. If damaged, it fails to release the detergent.

Dispenser Installation Issues

If the dispenser wasn’t properly installed and secured inside the dishwasher, it may not align correctly for the actuator to release the latch and open it.

Use these tips to troubleshoot and repair a non-functioning detergent dispenser:

1. Check for Obstructions

Remove any dishware potentially blocking the dispenser from opening fully during the wash cycle.

2. Clean Out the Dispenser

Remove all built up gunk, soap scum, and debris. Use vinegar, baking soda, and hot water solution.

3. Examine the Internal Components

4. Test the Dispenser Manually

Remove the dispenser to inspect the actuator, hinge, latch, and mechanisms. Replace any broken parts.

Use a hairdryer or hot water to heat the bi-metal actuator to see if the dispenser opens.

5. Inspect Wiring and Control Board

Check for damaged wiring or control board issues preventing dispenser activation.

6. Adjust Dispenser Installation

Loosen and straighten dispenser housing if needed and secure properly inside the dishwasher.

If still not functioning after trying these steps, the dispenser assembly may need replacement or professional diagnosis of electrical issues.

Preventing Dishwasher Dispenser Problems

You can proactively avoid issues with your dishwasher’s detergent dispenser:

  • Use dishwasher-recommended detergents to avoid excessive buildup.
  • Clean the dispenser regularly with hot water or vinegar solutions.
  • Take care not to crack the dispenser when refilling detergent.
  • Position large dishware to avoid obstructing dispenser operation.
  • Use a rinse aid to minimize mineral deposits.
  • Don’t overfill or clog the dispenser with too much detergent.
