1. Did you recently clean the dispenser? The dispenser needs to be cleaned regularly because it can’t drain water properly if detergent deposits build up. Otherwise, water may spill over the dispenser or leak. Clean the dispenser with a small brush (such as a toothbrush). 2. How much detergent do you use? Add the recommended amount of High Efficiency (HE) detergent. The most common reasons for water leaks in the dispenser are using too much detergent or using regular (non-High Efficiency or HE) detergent. Doing so may cause water leaks in the dispenser or excessive foam. 3. Do not leave the detergent in the dispenser too long. The detergent may harden and water may spill over the dispenser.
