Updated at: 28/03/2025

Is your dishwasher leaving dishes stubbornly dirty despite seemingly functioning correctly? The culprit might be a simple blockage in your detergent dispenser.

This frustrating problem is often easily solved with a bit of DIY know-how, saving you the expense and inconvenience of calling a repair service. Many times, a thorough cleaning is all that's needed to restore your dishwasher to its sparkling best.

Common Mistakes to Avoid

1. Forcing a Stuck Dispenser

Solution: Try soaking the dispenser in warm, soapy water to loosen any stubborn residue before attempting to open it.

2. Ignoring Small Debris

Reason: Small pieces of food or detergent can easily accumulate and block the dispenser's opening, causing incomplete dispensing.
Solution: Thoroughly clean the dispenser area with a small brush or toothpick to remove all visible debris.

3. Using the Wrong Cleaning Tools

Reason: Using abrasive cleaners or sharp tools can scratch the dispenser's surface, leading to further problems.
Solution: Use a soft-bristled brush and mild soapy water to avoid damaging the dispenser's delicate components.

FAQs

My dishwasher dispenser is completely clogged and nothing seems to be working. What should I do?
If soaking and rinsing the dispenser doesn't clear the blockage, you may need to resort to more forceful methods. Try using a thin, flexible tool like a straightened wire coat hanger or a pipe cleaner to carefully probe and dislodge any stubborn debris. If the blockage persists, consult your dishwasher's manual or contact a repair professional for assistance. It's possible there's a more serious internal issue.
