The soap dispenser isn't opening all the way. Therefore it leaves a small amount of soap in the chamber after the rinse and dry cycle. How do I fix it?

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...

Soap dispenser does not open during wash

Hi there,

Well you can please follow the below steps -
1. Remove any dishes in the dishwasher. Unhook the dishwasher's dish trays or racks from their tracks, and set aside. Empty the soap dispenser if it contains unused soap that failed to dispense. Use a wet rag to wipe down the interior of the dishwasher, as well as the inside of the dispenser.
2. Close the dispenser, and shut the dishwasher door. Turn the dishwasher on to a manual setting, then stop it and open the appliance. Check to see if the dispenser is open. If it is, continue to Step 2. If the dispenser is closed, skip to Step 4.

3. Switch dishwasher soap. Some dishwasher dispensers have difficulty with dry or liquid dishwashing soap, depending on the make and model of your dishwasher. Incompatibilities typically result in the dispenser sticking shut, which explains why the dispenser opens when empty. Switch to liquid soap if you are using dry powder soap, or vice versa.

4. Check the dishwasher soap dispenser's spring. The spring is located behind the dispenser top's hinge. Consult your dishwasher's original manufacturer's manual or user guide to find a replacement spring. Pop the old spring out with a screwdriver, and replace with a new spring. This should resolve any issues related to the dispenser failing to open.
Please post comments if you need more help or information..........

Good Luck!!

My soap won't dissolve during the cycle.

You are not getting enough water or you are losing the water during wash cycle. Is you dishwasher new or older? How is it plumbed in? If it is plumbed through the floor you will have to put and air gap in to keep the water in it. All tall tub dishwasher have to be plumbed properly.
