All I can suggest is buy a new battery from a trusted supplier like Samsung or your network provider. If you have the equipment, try checking the polarity on the battery, it could have blown out.

The problem you are experiencing tells me that the air switch in the motor most likely the problem.
This is a latching air switch that operates when the button on the side of the tub is pushed.

You will need to remove the front control panel assembly (2 screws and 1 ribbon cable) with copier opened like removing a paper misfeed (or replacing toner unit). Next, you will need to separate circuit board from control panel in order to gain access to the switch under the green print button. Sometimes, you can use electrical contact cleaner (tuner cleaner) to spray into the switch itself, pressing the switch numerous times to evaporate the solution from inside contacts of said switch. Now use a multimeter to check for continuity while depressing the switch and releasing. If cleaning the switch fails, either the switch will need to be replaced or the control circuit board will need to be replaced...replacing the switch isn't difficult, if you know how to solder. Reassembly is reverse of disassembly.

The kitchenaid dishwasher (model KUDC25CHSS1) appears to have the 'child lock' engaged on the led display panel. The 'energy saver dry' light is flashing red and when I attempt to push 'cancel' it only...

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.

If thats the case then its probably the cable from your screen to the motherboard. This cable is called the screen ribbon cable. these cables are not meant to be pulled out and in more than 2 times and after that they become unpredictable. Ask the shop if they can replace it.
