    it takes a little bit of time but hoow your meter up to the wax motor and start the dishwasher and just wait you should see the voltages change.

Whirlpool quiet partner I soap dispenser won't close


Hi


Dishwashers use Bi-Metal strip to allow the dispenser to open/close. This strip when heat up causes the soap door spring to open up the dispenser. If this strip is not heated doesn't allow the door to open. The strip may not be getting 120V or maybe disconnected. Newer (plastic liner) dishwashers use a wax motor to open the soap dispenser. The plunger inside the wax motor slowly moves and pushes the plunger and door open. And, if this wax motor doesn't receive 120 volts, then it'll not work. Please check the voltage to the wax motor/Bi-metal strip; also inspect the connections to these.


Hope this helps...

The soap dispenser fails to open at times


Hi


Bosch dishwashers (not all) use a BI-metal strip that heats up once power is applied to it. The BI-metal strip bends and allows the soap door spring to open up the dispenser. This bi-metal strip is not given full 120 volts power, the timer "shunts" the power through either the heating element ( most common ) or the motor and this gives the bi-metal strip lower than full power to work and open. Most often the bi-metal strip has lost its ability to bend properly and needs to be replaced.

Older Bosch dishwashers used a mechanical arm driven by the timer to open the dispenser = no electrical bi-metals. Newer (plastic liner) dishwashers use a wax motor to open the soap dispenser. The plunger inside the wax motor slowly moves and pushes the plunger and door open. And, if this wax motor doesn’t receive 120 volts, then it’ll not work.
