LG dishwasher detergent cup will not stay closed.

The latch seems to not be catching. The spring is fine, it's the locking mechanism that seems to be failing. Suggestions?

I do not know which machine you have , but it sounds like the plastic catch on the dispenser has worn down. You would need to replace the dispenser unit.

Soap remains in dispenser after completed cycle and dishes are not clean


Hello laura.... there are three possible causes of the dispenser not opening:

1.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. 2. 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. 3. 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 That said, one way around this is to simply add the soap or the soap tab into the dishwasher proper, not into the cup. Joe Thanks for choosing Fixya!

If the detergent cup doesn't open, check the detergent cup, the bi-metal switch or wax motor, and the timer. Make sure that no dishes are blocking it from opening.
The cup that holds the detergents can get caked and gooped up with old detergent. You should try to clean away any old detergent. If you can't clean the detergent away, you should replace the cup.
The bi-metal switch is activated by the timer and is an electrically operated device that bends when electricity is applied to it. It uses two different metals that are bonded together. As they warm up, they expand at different rates causing the metal to bend. The degree of bending can be set with a high degree of precision. Many devices use the bi-metal switch. A lot of newer dishwashers use a wax motor instead of the bi-metal switch. The wax motor has a wax block that gets heated up when the timer sends electricity to it. The wax expands as it gets heated up, and it pushes a plunger that opens the detergent door. Depending on how your dishwasher is wired, the switch may be wired through the motor circuitry or through the heating element. If the heating element is broken, there will be no electricity to properly activate the switch or heat the wax block in the wax motor to open the cup. If the motor doesn’t let enough electricity through its circuit, the bi-metal switch won't operate properly, or the wax motor wax block won't get heated up to expand and push the plunger.
On many dishwashers, an actuator arm links the timer to the detergent cup. When the timer reaches the correct time of the cycle, it activates a lever that opens the cup. If this link is broken or in any other respect faulty, the cup will stay closed, and won't let the detergent into the dishwasher. Check this linkage and either fix or replace it.

Detergent dispenser problem


Is it new? Even if it was or wasn't, I strongly feel that you probably didn't set something properly. Read the manual it came with, particularly the troubleshooting section. Not a big problem. Let me know how it goes. :)

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.

Detergent cap


Thanks for the model number. On your particular unit you can only latch the unit in the off position. If it still does not latch, open the door and remove all thr screws you see. Normal seven of them. Now, split the door and take a close look at the locking mechanism. Did something come loose? Is the spring in tact...Play with it and see how it works,...then what must be done to repair. It is really a simple system and has been tried and tested for many years in the GE Dishwashing Units. Good Luck, Eric Campion

The cover of detergent dispenser does not open..


It is most likely the flip spring...you need to be certain that the legs of the spring are inside the door edge and the spring does not swing freely...and there must be tension on the spring so that when the latch releases the door flips...you can also try this with an elastic, put the elastic inside the closed door and up around the drying solution knob, this will let the door flip open showing that the latch does work
