The child lock engaged when a circuit breaker triped. I tried pushing the Rinse Only pad as per the manual. But, the dishwasher remains locked (light on) and won't run.

Try pressing and holding the Rinse button (between the Wash and Spin buttons) for 3+ seconds. This should toggle the Child Lock off and the Start button should work to resume the cycle. (If you have touched the Power button, you may need to turn on the washer first. The Child Lock feature remains in the last used state.) See page 27 of the Owner's Manual for information on the feature. The manual is available from the manufacturer's support page: http://www.lg.com/au/support/support-product/lg-WTG7532W#manuals . The current link to the manual is http://www.lg.com/au/lgecs.downloadFile.ldwf?DOC_ID=20150102039896&what=MANUAL&fromSystem=LG.COM&fileId=SVYMjStXlkiH8PNt0qdVA&ORIGINAL_NAME_b1_a1=MFL67568754-Eng.pdf .

If you can't get the Rinse button to respond, you may have a problem with the touch pad circuit board, the wiring between the touch pad and the control board or the main control board.

I hope this helps.

Child Lock Controls
To prevent children from accidently changing the
dishwasher cycle or starting the dishwasher, lock the
dishwasher controls by pressing and releasing the RINSE
ONLY pad (some models) or the NO HEAT DRY pad (some
models) for 3 seconds while the door is latched. An
indicator light on the lock graphic pad will illuminate when
the controls are locked and no new selections can be made
until the lock is released. To unlock the controls, press the
same pad, RINSE ONLY or NO HEAT DRY, again for 2
seoncds until the indicator light goes out.


Hope this helps?

Hello Ray E. Weaver - Sounds like the Child Lock option may have been selected. This is a safety feature that allows you to lock and unlock the controls to keep children from interfering with the wash cycle etc. Press and hold the AIR DRY pad button for 3 seconds while the door is latched. This should unlock the control pad for you, light goes out and the unit will display the last cycle ran. However, if it does not, try resetting the unit by unplugging it for flipping the household circuit breaker off. Wait approximately ten minutes and turn the unit back on. However, if it proves to be ineffective I recommend contacting a professional to assist further. The dishwasher may possibly have faulty door lock switch.

Try finding the electrical circuit that powers your dishwasher. Turn off the breaker for a while (15-30 min.) This may reset the computer to factory defaults.

Hi,

Please find complete process to switch off the child lock.

Most of the dishwashers are same so the model should not be a problem

Thanks

WASH THE DISHES URESELF U LAZY ****!!! :)

On my unit, I had the same problem (child lock LED on, or flashing.The cancel process of pushing anything was not possible, as a bad/stuck switch prevented any input from the control panel buttons.

The underlying cause of the problem turned out to be a faulty switch associated with the "Light China" button. I determined this by removing the control panel from the door and using a digital multimeter with OHMS and DIODE settings, was able to check each individual push-button switch using the following table to check the 12 switches (applies to the KUDC25CHSS1 model).

There are 2 ribbon cables, it is the larger of the two cables you need to check. Pin 1 is noted on the ribbon. You can use 2 normal sized paper clips to insert into the ribbon cable and make your connections. (My Ohm meter has aligator clips on its leads which helps a lot...maybe another set of hands would help if you don't have these kind of leads).

-Using OHMS: the reading should be infinite (open circuit, so no reading/no connection inside the switch) when not pushing the button, otherwise you will receive a reading when you push the switch.

-Using DIODE/beep: Ensure polarity is followed in the table below. When connected, pushing the associated button will cause a beep to occur, otherwise there will be no beep and no reading.

+Positive Lead -Negative lead
Antibacterial Sw 13 3
Rinse Only Sw 13 2
Light China Sw 11 2
Normal Switch 13 4
Delay Switch 11 4
Energy Save Dry 13 5
Cancel 12 5
Start 11 5
Soak & Scrub 12 6
Super Scrub 11 6
Short Wash 12 4
Sani Rinse 11 3

All my switches checked out OK, except for the "Light China" switch. On the OHMS settings I was never able to measure an open circuit for that switch, which means the switch was always closed. or connected.

I noticed that "Light China" was pin 2 and "Rinse only" also used pin 2, which happen to be cycles I never use. With power turned off, I carefully removed some of the plastic surround of the matching connector on the Control Board right next to it's associated Pin 2 all the way to the bottom. Then I carefully bent over pin 2 as close to the connector base as possible. Making sure all the remaining pins were straight, I plugged on the control panel ribbon cables and all is well again.

Prior to trying this I was resolved that I needed to buy a new dishwasher because I wasn't going to pay over $350 for a new control panel. Instead, I eliminated 2 unused cycles at no cost, and maybe I can get some more use out of this dishwasher.

silly question but did you try holding the control lock button(perhaps its the heated dry button) in for 3 secs???? sonds as if the CONTROL LOCK has benn activated( child lockout)

To prevent a child from accidently starting the dishwasher there is a child lockout feature. Press and hold the Rinse and Hold pad (certain models) or the No Heat dry pad (certain models) for # seconds to Lock or UnLock the controls

the solution is to change the electronic control.....cost 110$
