My dishwasher lights up when the "start" button is pushed, but the cycle does not start. I can hear a faint humming sound like it wants to start. It worked perfectly two days ago and I am wondering if it is because of the extremely cold weather we are having. None of my pipes are frozen in my house, so I am not sure if something could be frozen within my dishwasher.

Re: Kenmore dishwasher 15762
On the inside of the dishwasher (on the bottom), there should be a little "float" device, which tells the dishwasher when it has put enough water into the tub. Sometimes, this float gets stuck in the "up" position, so the dishwasher never puts any water in, but continues to run anyway as if it did. Try pushing down on the float to unstick it, then start the cycle over and see if it puts any water in.

The faint "hum" sound is your wash motor trying to turn on. You either have a piece of glass/tooth pick/ ect.. or a worn out bearing. Its time to change your wash motor. If you do a DIY you can save money over having a service man come out and charge about the cost of a new one.
Best of luck!

THE HUMMING NOISE THAT YOU ARE HEARING IS THE ELECTRONIC DRAIN MTR ACTIVATING BUT YOU HAVE NO WATER IN THE SYS. SO IT SOUND LOUDER AND DIFFERENT THE HUMMING IS THE LESS OF YOUR WORRIES THAT IS NORMAL BUT WHAT IS NOT NORMAL IS THE CLEAN LIGHT FLASHING IF IT FLASHES 7 TIMES THEN PAUSES YOU HAVEA BAD PROCESSING BOARD AND ALSO A HEATER ON SOME OF THE KM MODELS THE CONTROL BOARD AND HEATER IS SOLD AS A KIT. TO VERIFY THAT THIS IS THE CASE GO TO WWW.SEARSPARTS.COM . BUT FIRST ALSO CHECK TO SEE IF YOU HAVE A BURNT WIRE AT THE HEATER ASSEMBLY WHICH WOULD REQUIRE PULLING THE DW OUT. GOOD LUCK
