Whirlpool, quiet wash plus, dishwasher

Whirlpool dishwashers use a wax motor or a solinoid to release the door at a specific time during the cycle. So for proper cleaning the soap cup is nessesary . The part isn't that expensive and fairly simple repair.

The detergent dispenser lid spring may be stuck or the solenoid faulty. Might have to replace the detergent dispenser.

Best to check which one of these two might fit your model.

The problem is with either the spring or the solenoid that operates the detergent compartment door. It should be released at the right time by the controller during wash cycle. You have to check the spring and see if it stuck. But if solenoid is faulty then whole detergent dispenser has to be replaced. You could switch to detergent tablet which you drop in the cutlery basket and it works fine. A brand like Finish works well and keeps dishwasher clean.
Alternatively you can purchase a replace detergent dispenser from

Bi-Metal

If the dishwasher dispenser doesn't work the bi-metal actuator might be burned out or defective. The bi-metal is a simple metal loop which acts as a latch for the dispenser door. As electricity is applied to the metal loop, the loop deforms and bends away from the latch, releasing it. If the bi-metal is burned out it won't deform or release the detergent door.

Main Control Board

The main control board provides power to nearly every component of the dishwasher including the detergent dispenser. If the dispenser will not actuate the main control board might be defective. You should first check for more common parts. Many times control boards are replaced unnecessarily because the problem was not diagnosed properly.

God bless you . see the photo attached.

Is there a tall dish/cookie sheet/pan blocking the dispenser door from opening fully? Check inside the rack of the dishwasher to see where the dispenser door lines up.

Hi,

There are three common problems that cause the Soap Dispenser or Cup not to open. I have a tip that will explain these problems in detail....

Dishwasher Repair Problem Detergent Cup does not Open

I would replace the control board. Since the problem is intermittent this would indicate that the controller is not consistently sending voltage to the dispenser to open.

I bet your clumps of soap began with the beginning of the use of a different DW detergent powder.

Try this (trust me) Go buy a box of brand name Dishwasher powder (e.g. Electrosol or Cascade) Use it for two loads of dishes and report your results back here. OK?

check to see if anything like dried up soap in there if so wash out with warm water or try a liquid
