The detergent dispenser is for releasing the detergent and softener (liquid or powder) that your dishwasher needs.
With use, the valve on your detergent dispenser can start deteriorating or the opening mechanism can become faulty.
A defective detergent dispenser can result in many issues that affect how well your dishwasher washes your tableware, such as the dishwasher detergent getting released too soon during the washing, pre-rinsing or soaking cycle. It could also mean your tableware won't get washed properly.
You may want to consider ordering a new replacement for your detergent dispenser from our site. We have an extensive range of different kinds available.
