Humming from wax motor

In your last response concerning the detergent dispenser and wax motor, are you stating that I probably need a new control board since the motor is continuously getting a signal to operate?

    Yes, it is a tall tub. The dishwasher is just over a year old and I did not purchase the extended warranty. Is there a recall on that control board? I heard of several people having the same problem! Is this an item that is normally covered longer under the original manufacturer warranty? I decided that if it is not covered, I might just disconnect the solenoid and not have a pre-wash cycle with detergent. I will just put a detergent block in the dishwasher itself.

Yes the voltage is sent from control bd ..it is supposed to be only a brief time period but due to malfunction it is continously energized resulting in overheat..i believe you said that was a whirpool/kenmore/kitchenaid..had that happen several times ..especially on the talltubs they are controlled by solenoids not wax motors those have a rectangular dispener on left of inner door..if yours is a short tub with dispenser on right side of inner door those were wax motors have had one just go bad and not operate at all

    that controls detergent for second wash not first if you prewash your dishes before putting them into machine you might get by ok without second wash..ck your owners manual for warranty controls sometimes has 2 yrs if you choose to disconnect be sure to tape wires to prevent short..not sure if total failure will occur later or not let know outcome thanks..gene

What is wax motor on dishwasher


They are used in many dishwashers to release the detergent dispenser door latch. The wax motor acts like a solenoid when activated by the dishwasher's timer or control, and the piston operates the mechanism which then releases the catch for the dispenser door.

In simpler terms, the motor that releases the cover over the dishwasher detergent well is called the wax motor.

Soap dispenser will not open automatically in a wash cycle


Hello there:
Please follow thew following solutions i have provided below
The detergent cup doesn't open When the detergent cup or dispenser will not operate properly or doesn't open, check these:
Timer On many dishwashers, a plastic actuator arm mechanically links the timer to the detergent cup. When the timer reaches the proper time in the cycle, the timer activates a lever that opens the detergent cup. If the linkage is broken or defective, the cup stays closed after you've closed it. Check the link and repair or replace it, as necessary. Bi-metal switch or wax motor A bi-metal switch is a simple electrical device that deforms when electricity is applied to it. The degree of this deformation can be engineered to concise standards. The timer energizes the bi-metal switch inside your dishwasher door--directly behind the detergent cup--when the detergent cup should open. When energized, the bi-metal switch deforms away from the detergent cup latch, which opens the detergent cup. If the bi-metal switch is defective, it may not deform enough to open the cup. If that happens, you need to replace it. On some dishwashers, the bimetal switch is wired through the heating element or motor circuit. If the element is broken (or open), or if the motor is drawing low current because of a low-fill situation, the bi-metal switch doesn't open properly. Newer dishwasher models use a wax motor instead of a bi-metal switch. It's a sealed unit with wax that heats up and pushes a piston through to open the door. The wax motor, controlled by the timer, mechanically opens the door. Detergent cup, itself The detergent cup itself can become clogged with old dried detergent that prevents it from opening. Sometimes just cleaning the cup takes care of the problem. If not, you probably need to replace the entire cup assembly

Soap dispenser does not open during wash cycle


  • Hi,


    please try this...
    imer:
            On mechanical set ups the timer is attached to the detergent cup by an actuator arm. This arm is usually plastic, and if it is broken or otherwise defective then the detergent cup wont be opened. Check the linkage to make sure it is functioning correctly.
    Bi-metal switch or wax motor:
            The bi-metal switch is simply a very precise device that warps, bends, or otherwise deforms when power is supplied to it. The timer operates the bi-metal switch, which inside the dishwasher door. Then the switch is supplied with power and it is working properly, the bi-metal switch deforms away from the latch holding the detergent cup closed and the cup opens dumping the detergent into the washer.
            Some dishwashers have this switch wired through the motor power feed or the heating element. If they are defective then the detergent door will not operate correctly. If the switch itself is defective then you will need to replace it. Another type of mechanism is a wax motor. Wax motors are sealed units filled with wax and found in newer dishwashers and work by heating the wax and forcing up a piston which in turn mechanically opens the detergent cup door. This type of device is also controlled by the timer.
     
    Detergent cup:
            Sometimes the detergent cup becomes built up with old detergent that prevents it from opening correctly. It's usually a simple fix to clean this out. If cleaning it is impossible then you may need to replace the cup assembly.

    please rate my suggestion..
