Won't start a program: Codes, Causes & Fixes

When an appliance won't start a program, the cause is often simple: the door isn't fully latched, child lock or delay start is active, the water supply is off, or the outlet or breaker has no power. Check those, then unplug the appliance for a few minutes to reset the electronics. If a door lock or door switch code appears, or the display stays dark, the latch, switch or control board may need attention.
