How to reset?

Reset can be performed on many device and units.
Ok, many things will work again only after they are "Reset" now to reset your device, if it has a battery, it MUST be removed totally, if on Power, it must be removed, if on BOTH, both must be removed, wait 5 mins or so, then look around the edge back, side, of your unit for a small hole & or button, while the battery is out,power off, depress this button for say 10 seconds, then reattach battery and power up. The unit, with any luck, it should be working again. If it doesn't work first time, simply try again, BUT this time wait like 20 mins, before you try to press the "Reset" button. Hopefully NOW you will be all good. If not then you have some "Other" sort of problem and that needs more inspection.

Dishwasher just makes humming noise?

This problem is rare on dishwasher.
There is a reset method, which helps to clear this non working humming dishwasher problem.
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.
This details should help you.
Thanks.
