3. Press the START / RESET button again, the dishwasher will resume
operation using the newly selected wash program / cycle.

I realize this is 2 years old, but all you do is hold down stop/cancel for 3 seconds. That also turns on child lock.

The manual is linked above. it says to press the buttons.

Hello Simon;

My name is Peter. I am a retired field service refrigeration technician.

You did not provide a model number so I do not know what unit you have.

No matter; Either you do not have a lock on your dispensers or you have a child lock out on the dispenser key pad. This lock will lock out both the water and ice dispense.

most dispensers have a hidden lock button that may be set the lock button is a child safety feature,despite that could be the door switch since they wont dispense with the door open or perhaps could be the switch on the dispenser cradle

Either the paddle for the ice/water dispenser is stuck or you have a bad microswitch behind the dispenser.
To stop the ice/water from dispensing open the freezer door and press or hold the child lock button down. Once the unit is in child lock mode you can shut the door without energizing the dispenser.
Another option is to remove the upper freezer door hinge cover and disconnect the wire connector up there. This will remove voltage from the dispenser as well. Then either replace the paddle or switch. Sometimes the paddles/switches will get stuck because of splash up from ice dropping in sugary drinks.

Your dispenser is child locked. Hold the child lock button for 4 seconds and the key should disappear, if you do not know which key to press I will need the model number from the tag located on inside of the fresh food section top right corner.

The obvious thing to check is to make sure child lock isn't turned on if it has that feature.

Usually, once child lock is on, the set will not respond to the front panel buttons and you need the power button on the remote control to turn the TV on. Then go into the menu and turn child lock off.
