Dishwasher not cleaning properly - soap dispenser does not empty. Dishes are not dry

The rinse aid or the rinse aid dispensing cap could be the reason why your dishwasheris not fully drying your dishes. Without the rinse aid, the dishes will not shed water easily and will not dry properly. First, make sure the rinse aid chamber is not empty.

Don't know if this will help, but my dishwasher has a "propeller" device above the top and bottom racks that spins while dispensing the water. If the dishes on either rack are stacked too high (i.e. if even one plate comes in contact with that propeller, keeping it from spinning properly) the dishwasher will go through its full cycle but will not use the soap (soap door will still be closed and soap packet still intact) and will not get the dishes clean.
However, it sounds like you either have a bit of a drain issue as well--or perhaps your dishwasher acts the same way as mine (if that's the case) but ceases to drain as well if blocked.

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

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!!

Thanks

Buy a new one. Whirlpool, Kenmore,or MayTag

run the dishwasher empty: use 1/2 the amount of soap you usually use in the soap dispenser close it then put white vinegar in the open dispenser and, run the dishwasher

generally dishwashers rely on the pressure supplied by the water supply line. check to see if it is enough or if inlet pipe is of sufficient diameter for needed flow.in some instances i know of seperate lines needing to be run directly instead of coming off of supply to sink area.

ok, either a spring, trigger prob, on the latch, or a electronic prob. ok so to see if the latch is ok (or not) look closely for soap residue and scum, that may be hindering the latch or spring under. use metho, and warm water to clean this part. secondly go down to a white goods repair place and take your electrical component, button, lights its all one unit, simple unscrew it, i do think you will need a set of torque screws for that tho... anyhow ask the guy to get you a new or second hand one and install it. the timer will run, and the clip will release. good luck!
