1. Check the Dispenser

The detergent dispenser is critical for a proper wash. Over time, remnants of detergent can harden and clog up the dispenser, affecting its efficiency. Here’s a detailed way to check it.


Open the Dishwasher: Safely open your dishwasher and locate the detergent dispenser, usually found on the door’s interior.

Inspect for Build-up: Carefully look for any signs of hardened detergent or soap scum that might be blocking the dispenser’s outlet.

Clean the Dispenser: If you find any hardened detergent, use a soft cloth or sponge to gently scrub it away. For stubborn deposits, you might use a small amount of warm water to loosen them up.

Run a Rinse Cycle: Close the dishwasher and run a short rinse cycle to see if the dispenser now empties the detergent completely.

Check After the Cycle: Open the dishwasher again and inspect the dispenser to confirm that it’s empty.

2. Examine the Cycle Settings

Your dishwasher offers various cycle settings designed for different types of washes. Using the wrong cycle could result in incomplete detergent usage.

Consult the Manual: Every dishwasher comes with a user manual that explains the different cycle settings. Take some time to review this information.

Select the Appropriate Cycle: Ensure you’re using a cycle that requires the use of detergent. Some quick or rinse cycles may not use detergent at all.

Run a Test: Run a normal dishwasher cycle using the settings you’ve selected.

Inspect After the Cycle: Once the cycle is complete, open the dishwasher and see if the detergent has been used up completely.

Ensure that you’re not overloading your dishwasher as this can also affect detergent usage.

3. Clean the Spray Jets

Clogged spray jets can affect the circulation of water and detergent in the dishwasher, thus affecting the cleaning process.


Locate the Spray Arms: Open your dishwasher and locate the spray arms, which are usually found below the upper rack and at the base of the dishwasher.

Use a Toothpick: Carefully use a toothpick to clear out any food particles or debris that might be lodged in the holes of the spray arms.

Run a Rinse Cycle: After you’ve cleared the jets, run a rinse cycle to remove any loose debris and to verify that water is spraying evenly from all jets.

4. Inspect the Dispenser Door

A malfunctioning dispenser door won’t open at the right time during the cycle, preventing the detergent from being used.


Check Movement: Open and close the dispenser door multiple times to check if it’s moving freely.

Look for Obstructions: Ensure that there’s no debris or utensils preventing the dispenser door from opening fully.

Consult the Manual: If the door seems stiff or doesn’t open easily, refer to the appliance manual for specific instructions or replacement procedures.

5. Consider Detergent Quality

The quality of the detergent you use plays a significant role in how well your dishwasher performs. Subpar detergents may not only compromise the cleanliness of your dishes but can also leave residue in the dispenser, contributing to the problem of the dishwasher not using all detergent.

Switch Brands

Using a generic or budget-friendly detergent might seem like a good way to save money, but it could cost you in terms of cleaning performance and machine maintenance.

What to Do:

Research Brands: Look for detergents that have received good reviews or are recommended by dishwasher manufacturers. Brands like Finish, Cascade, and Fairy are generally well-regarded.

Make the Switch: Purchase a small package of the better-quality detergent for a trial run. This will help you assess if the new detergent solves your problem without committing to a large purchase.

Choose Liquid Over Solids

Liquid detergents tend to dissolve more easily and quickly in water compared to tablets or powders. This ensures a more uniform distribution of detergent during the wash cycle, which can lead to better cleaning and full use of the detergent.

What to Do:

Read the Manual: Check your dishwasher manual to see if there is a specific recommendation regarding detergent form. Some newer machines are optimized for specific types.

Opt for Liquid: Next time you’re shopping, pick up liquid dishwasher detergent instead of tablets or powders.

Run a Test Cycle: After switching to liquid detergent, run a standard wash cycle and inspect both your dishes and the detergent dispenser to gauge performance.

Dos and Don’ts

Do read the instructions on the detergent packaging to ensure you’re using the correct amount.

Don’t mix different types or brands of detergent, as they may have different chemical compositions and could interfere with each other’s effectiveness.

If you’ve switched detergents and you’re still experiencing issues, it may be a good idea to consult your dishwasher’s manual for additional troubleshooting tips, or seek advice from a qualified service technician.
