New dishwasher fills with water but does not start washing

sounds like a bad timer

It sounds like your motor is stuck in the reverse position. It could also be in your timer. I would suggest calling a qualified technician for the one. Just because the parts are pricey and depending on how much a new dishwasher cost. Atleast get a diagnosis so you can know if its worth fixing or buying a new one. If you have anymore questions please feel free to comment me back.

It is unclear from your description if the wash pump starts and pushes the water around but never stops cycle or the dishwasher stops as soon as the water is filled.

If you do not hear the wash pump start then it is possible the wash motor is faulty. But if the wash pump starts and never completes the wash cycle then it is possible the heater is faulty and dishwasher is waiting for water to heat up before it can go to next cycle.

See the attached diagram for location of wash pump motor and heater.

Hope this helps you find the problem. Please rate the solution if you found it useful.

THAT IS NOT NORMAL!!!!!!! A normal wash and dry cycle will take approx. 2 hours in length including drying cycle.
You should see that water has been present in the machine within the first 2 minutes of the start of the wash cycle, you should also be able to hear the water entering the wash tub.
The fill valve or water supply seems to be the issue, if the water doesn't enter the tub then the controller won't proceed witht the wash cycle. Double check your water supply tube / hose to make sure there is water present at the connection to the dishwasher.
GOOD LUCK !

Dishwashers today use a lot less water and energy to do this they filter the water like crazy this makes the wash times go way up, the motor used today uses only a little power so a long cycle does not cost much.

They average wash time for a new machine is 90 - 120 minutes. Some high efficiency units can run 4 hours per cycle.

Most likely causes are:

Not enough water entering dishwasher (check level after fill... Should be slightly below bottom wash arm)

Water filling but draining during wash cycle. Check toward end of wash cycle but before drain. See if water level is diminished from start of wash cycle.

New 'water saver' dishwashers are notorious for having smaller water jets, and thus easier to stop-up jets. Check the jets on all wash arms to be sure they are cleared of food particles.

Another way to check the wash arms is to manually position them at specific locations, momentarily run the dishwasher for a few seconds, then open the door to inspect the location of the wash arms. Do this three or four times to eliminate the possibility of coincidence.

If the wash arms do not move from the location that you put them, the most likely cause is food particles stopping up the water jets. These jets not only clean the dishes but also the water pressure they generate turn the arms inside the dishwasher to properly distribute water pressure on the dishes.

Sometimes you can dislodge and remove food particles stuck in one of the jets with a toothpick or other small probe. Others require that you remove the arm(s) and get a little more creative. I use compressed air to clear mine, but not everyone has access to compressed air, so use whatever you can to remove the food particles.

Simply dislodging them from the water ports is usually not effective... As soon as water pressure is applied, the particles return to the jets and stop them up again. The real fix in this instance is to completely remove the food particles from the arm if you can.

Hope this help. Good luck.

The float switch in the tank is bad,also if water only trickles in your fill valve is going bad which will not let it fill all the way to start wash cycle. Fill tub with pot of water to raise float, if wash cycle starts,replace fill valve,if not,replace float switch.

is your water temp set at 120 degrees

the problem is the float switch is stuck
