KitchenAid Dishwasher PO Code: Delay Start Counting Down
Quick Answer
KitchenAid PO is a delay start status indicator that gets misread as an error code by many users because it appears unexpectedly on the display. The key fact: PO is not a fault. If you set a delay start and then forgot about it, PO will show until the countdown reaches zero and the cycle begins.
I get calls about this one constantly. Homeowners think their control board's fried or the whole panel went haywire. Nope. KitchenAid touchpads are incredibly sensitive and it's super easy to brush the Delay button while you're leaning against the counter loading the bottom rack. When you see PO, your machine's doing exactly what it was told to do. It's just waiting. Not broken.
What Does the PO Code Mean?
When you see PO on the display, there's usually a number right next to it like 2, 4, or 8. That's your dishwasher telling you how many hours it's planning to sit there before it starts washing. Honestly, this is one of the few codes I show up for where zero tools and zero parts are involved. One button press and you're done.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Symptoms You May Notice
- PO shows on the display panel, sometimes with a number like 2, 4, or 8 right next to it counting down the hours left before the machine starts.
- You press Start and absolutely nothing happens. The machine just sits there with PO on the screen like it's ignoring you.
- Display lights are all on, door's latched, everything looks ready to go, but no water, no hum, no cycle starting.
- The number next to PO is slowly ticking down on its own, so PO 4 eventually becomes PO 3 then PO 2 while the machine just waits.
Can you reset a Kitchenaid dishwasher to clear the PO code?
Press the Cancel or Cancel/Drain button once. You'll hear the drain pump run for about 30 seconds, that's normal. Once it stops and the display clears, you're reset. Now select your wash cycle and press Start without touching the Delay button. On most KitchenAid models the Delay button sits right next to Start, so just be deliberate about which one you're pressing.
