Whirlpool Dispenser problem or not

The attachment I have included is from your web site and shows the AP3776575 Whirlpool Dispenser Assembly which has a white solenoid looking part which is making fluttering sound when the dishwasher goes into the wash cycle to release the detergent and it does not stop making this annoying noise until you stop the cycle. So want to confirm if all I need is to replace this assembly to solve this problem or is there additional parts I need to order because I really don’t want to have to place two orders or return items I didn’t need. Please confirm. Thanks, Carlos

The cause of the problem can be a bad dispenser as well as a bad control board. If the power to the dispenser stays on longer than it suppose to be then the problem is a bad control board.
