Narrow it down
What this symptom can tell you
The dispenser door stays closed
A utensil, rack item, sticky residue, or a dispenser issue may be preventing release.
The dispenser opens but detergent remains
Low water temperature, weak circulation, a short cycle, or old or damp detergent may be involved.
Detergent is found on the tub floor
The pod or tablet may have dropped without receiving enough spray or time to dissolve.
These patterns narrow the next check; they do not confirm a failed part. Use the exact model number and any displayed code before ordering parts or authorizing repair.

Common questions
Dishwasher detergent not dissolving: FAQs
Should I put a dishwasher pod in the bottom of the tub?
Use the dispenser location specified by the detergent and dishwasher manufacturers. Placing it elsewhere can release detergent during the wrong phase.
Does water temperature affect detergent dissolving?
Yes, but the safe temperature and heating method vary by model. Use the household and dishwasher settings listed in the manual rather than increasing them blindly.
Why does powder clump in the dispenser?
A wet dispenser, damp storage, or old detergent can make powder stick. Keep the cup dry before loading and store detergent as directed.
