Similar problem to other threads, where the dishwasher won’t start and beeps 3 times. I’ve replaced the control board (new control board now flashes 1x every 3 seconds) and the door latch. Still beeps and diagnostic mode says the door is open (all lights flash)

Ok, check the door latch strike to make sure that was not cracked or broken.

Here it is for your model:
WD13X10071 Striker Latch

Thanks, Jake - the door strike is not cracked and is making a solid seal. The door closes the same and as tightly/securely as it did when it worked. Last time this happened, I turned the circuit breaker on/off and it worked, but not this time despite multiple attempts.

Ok, if the door strike is good, then it can ONLY be TWO parts causing it, the door latch switch OR machine control board.

If you replaced them both already, then one is bad right off the bat, lets ohm test the door latch switch first to see if that's good. You will need a multimeter to ohm test it.

--->Here's the machine control board for your model: WD21X24901 Machine Control

Here's the door latch switch for your model:
WD21X10490 Latch Switch


Follow the directions here:

Door closed: 0 ohms.
Door open: infinite ohms.

Let us know what you find. Make sure you disconnect power to the dishwasher before ohm testing.
