Dishwasher won't stop when door is opened mid-cycle

Defective washer control board is the most common fault.

how to unlock or open the sealed door

The main processor was interuppted and so has hung up or is faulty. Remove the main plug and press on the control pad of the washing machine to drain off any residual voltage that is remaining on the main board and which seems to have hung up the processor.When the plug is plugged in and switch please hold down the start/stop button.
If there is no result after plugging in the machine then the main controller board is a suspect. You can remove the control board and check the connectors, check the main door switch , if possible clean the connectors/ contacts as a last chance.

Dishwasher will not start Is the door open or unlatched?
Make sure the door is completely closed and latched. On models with a dual-digit display, the control displays "- -" during a cycle if it believes the door is not latched. Check for obstructions (spoons, etc), interfering with the door operation. A lower dish rack that is installed backward will also cause incomplete door closure.

Check your household electrical box to see if a fuse has blown or if the circuit breaker has tripped. If the unit has a plug-in power cord, make sure it is plugged in.

Does your dishwasher have a rotary timer knob? (Some Models)
The cycle selection must match the position of the timer knob. Turn the timer knob to the beginning of the preferred cycle. The timer knob should click when you reach the start of the cycle.

Is the control lock option activated?
Press and hold the Heated Dry option (button with lock icon) for three to five seconds and the light should turn off. Instructions are also placed on the label on top of the inner door to unlock the controls.

Is the delay start option activated?
To cancel the delay and cycle, press Cancel/Drain.

Has the motor stopped for less than 10 minutes?
The motor may have stopped due to an overload. If this is the case, the motor will automatically reset itself within 5-10 minutes.

Is the Start/Resume indicator flashing?
Opening the door or interrupting the power can stop the cycle. Close the door and press Start/Resume. If the Start/Resume indicator flashes three times when you press Start/Resume, the dishwasher is waiting for you to open the door after the last cycle. Open and close the door, and then press Start/Resume.
On models where the controls are on top of the door be sure to close the door within 3 seconds of pressing the Start/Resume to start or resume the dishwasher cycle.

Is the water shutoff valve (if installed) turned on?
Make sure that the water shutoff valve is turned on.

change pump or check filter.....

Ok so your dishwasher won't do anything... it justs sits there and "Hums" you can't make it respond to any controls, and the ONLY way to Stop it. is to unplug the unit, replugging back in it simply "Hums" again and will do nothing.
Now this happens because, the STOP Button, is pressed and the "Door Opened", during the Wash Cycle. This should NOT be done. You should NEVER TURN IT OFF MID-CYCLE. you should instead, Simply, pull on the handle, to Open the door, the system will take care of everything, after, you close it,and pick up where it left off. The turning OFF, makes the machine "Think" that a New Cycle, is going to be done, before the old one is finished, and resets itself to do it all again. But it still has water, that's not meant to be there so it must dump it out.
Now, the FIX. Take the Dishwasher, out, and tip over on it's side, tip to about a 45' angle. Water will come out from underneath, this is from a small "Overflow" reservoir. this reservoir has an "Anti-Flood" switch. The removing of this water will "Reset" this Switch, and allow the dishwasher to work again.
So what happens, is this, when the STOP button is pressed Mid-Cycle, the machine must "Dump" whatever water is still in the machine, into the "Overflow Reservoir". This water then causes the Anti-flood switch to jam, and this stops the machine, until it is reset,by the above method.

All the tall tub dishwashers made by Whirlpool (inc. Kenmore and Kithcenaid) must have the start button pressed after adding a dish. If the start button control light is blinking, you must press start. On those models with buttons on the top of the door you must, in addition, close the door within aprox 5 seconds after pushing start. Hope this helps. Ken

press sani and heat back and fourth then after all lights light close door and hit start then wait about 3 minutes. worked for me

Hi John I have the same problem, the manual says that it is because the water level is to low, this is checked by opening the door after the machine has stopped filling and before it starts to wash, the level should be 4mm above the main plastic filter ring, the level has two settings, these can be adjusted by pressing the start button and the On/Off button at the same time, release the start button and turn the control to economy 45,if the start light does not come on the level is set to normal, to increase level press the start button again and the light should come on, this will give you an increased filling time. it did no help me but it may help you. good luck
