Kitchenaid DW KUDS30FXSS Cycle starts then I hear a solenoid actuate 4 times then unit goes into cancel drain cycle

Main control board is bad. Drain sequence is a power on test, Main board is not sending signal to open valve or is sensing water is present in the machine when it is not.

Is it draining out the water?? Dishwashers fill, spray, and drain more than several times during a cycle. After starting a cycle, let the unit fill, start spraying, and then cancel the cycle--listen for the drain pump activating and pumping out the water. If water is not being drained properly(within a certain time limit), the unit will error code out and stop. Also, make sure the filter is clear--if it gets clogged with "muck", enough water won't be sprayed onto the dishes properly, the pump will require too much energy to try to pump water, the control will sense this and shut down the unit to protect it.

If you forgot the water supply and ran the unit, there is a chance that the valve has burned out or seized.

Press the Cancel/ Drain cycle for a few seconds. The dishwasher should reset itself. See if this makes any difference. Also first turn the mains power to dishwasher off and back on.

See my problem and solution. Sounds like you, too, are having a problem with the main control board (computer chip that controls the dishwasher), which is apparently a common problem with this model dishwasher. The part can be found here, for $211 (tax + shipping), and they have a 30-day return policy in the event that it does not fix the problem. It's an easy DIY fix. Hopefully this helps!

1. If the water is going onto the floor during the drain cycle there is either a hole in the hose or it is completely loose from the DW or a hole in the drain assembly under the sink but if that were the case you would have water under the sink also.
2. If it during the wash or rinse cycle then the seals are not sealing (door is not closed all the way or seals are bad) or the float at the right front of the DW is stuck allowing the DW to overfill with water.(you need to open the door and pull the float up and out as you do so push it up and down and listen for a clicking sound.(which indicates it is making contact with the fill solenoid)..if you here the clicking and the float is full of gunk (old soap and such) clean it out and replace it and run it through a cycle and monitor the DW to see if the fill cycle shuts off before the water reaches the overflow point.
3. the only other option is a possible rust through on the DW and or the drain and motor mount in the center of the DW where the food particles and water are drained...is loose and leaking or rusted through...(how old is the DW).
4. Also check to see there are no large particles around the door seal to prevent complete closure and sealing of the door seal. As well as the door latching properly (when closed can the door be moved or pulled open)?

I hope this helps and let me know if not Please relay model number, age and other specifics you feel are pertinent...thank you and please rate me if this helped...thanks again ...the Fang

FYI, for anyone else with the same symptoms. I took mine apart and found that the seal on the motor shaft failed and over time corroded the motor shaft bearing causing it to failed. I ordered full motor assembly from the parts store.

It may be the water inlet valve or the electronic control board. To check, remove the bottom toe panel. The valve will be on the left side. There will be live power, so use extreme CAUTION. Start the DW, 1. if you can hear the valve humming or the valve coil is getting warm, replace the valve. 2. Using a device with wires to check the power at plugs, connect to valve power connection, if power is present, replace valve else replace electronic control board.

i would check your drain for restrictions under sink. fill with water, and then cancel cycle, did you hear water draining freely??? sounds like a clog
