Sometimes you’ll open your dishwasher to find that the dishwasher pod is stuck or it didn’t fully dissolve. This could be down to a few reasons.
You jammed it into the dispenser drawer, and it got stuck, meaning it couldn’t wash away completely.
Something — such as a long spoon or whisk — was stopping the spray arm from spinning, meaning the detergent couldn’t fully dissolve.
The soap cup is blocked. Check that it’s fully open at the end of each cycle. If not, something has prevented it from opening.
There is a clog in the filter.
The water wasn’t hot enough.
Walk through each of these possibilities to find the reason why your detergent pod is still in the dishwasher.
