The short answer
This code pairs a machine that will not start with the Start or Resume indicator flashing three times when that key is pressed. A counted flash in response to a press is the console answering you: it received the command and is declining it, and the usual reason it declines is that the door is not latched.
Whirlpool dishwasher code as the manufacturer publishes it
Reference| Code | Meaning |
|---|---|
| 5-2 | Won't Start and Start/Resume key LED Flashes 3 Times When Start/Resume Key is Pressed |
What you observe alongside the code
- A counted flash each time the start key is pressed — A reply rather than a fault in the light.
- The cycle never begins — The command is being declined.
- The door closes softly with no click — The latch is not making.
- A rack or an item touching the inner door — Enough to hold the latch off by a fraction.
What triggers it, most likely first
- A door that is not fully latched — First: the machine will not start against an open latch under any circumstances, and a fraction is enough.
- A control or child lock engaged — Second: the console reads the press and refuses it, which is exactly what a counted flash looks like.
- An item in the rack holding the door open — Third: a pan handle or a board against the inner door, and the door feels shut to the hand.
- A worn latch or a failed door switch — Last: the latch clicks and the machine still refuses, which is the version that needs a part.
Check in this order, and why
- Push the door firmly until the latch clicks, then press start — The single most likely fix, and free.
- Check whether a control or child lock is set — Both make the console decline a press it has read.
- Look for items in the racks touching the inner door — A handle or board is enough.
- Treat the latch switch as the suspect only after the above — It sits inside the door panel.
Clearing the code, then the owner-safe checks
- Slide the racks fully in and push the door until it clicks — Listen for it; a soft close is not a latch.
About 5 min
- Release any control or child lock — Check your use guide for the gesture on your console.
About 5 min
- Press Start or Resume once and watch the indicator — A cycle that begins ends the diagnosis.
About 5 min
- STOP HERE if the latch clicks, no lock is set, and it still refuses — That is the door switch or its wiring, inside the door.
Before you open anything
Safety
Unplug the dishwasher or switch off its breaker before removing the toe panel or the inner door panel. A capacitor can hold a charge after the power is off, and the supply is not switched at the door. Bail any standing water out of the tub before working underneath, and go into the sump with gloves and a light — broken glass collects there.
When this code is a service call
Call when the door latches with a click, no lock is engaged, and the console still flashes back rather than starting: that points at the door switch or its wiring inside the door panel. Nothing is at risk while the machine refuses to start, so this is a routine appointment rather than an urgent one.

Which model lines this reading applies to
This reading of 5-2 applies to Whirlpool-built built-in dishwashers of the generation whose service documentation publishes this code, which is where the manufacturer documents it. A machine with a mechanical timer and no diagnostic display does not produce it, and the same characters can be published against a different fault on a KitchenAid or Maytag-badged unit from the same platform. The number of flashes and what each count indicates differ by console generation on this platform. Where a model-specific page exists for your unit it is linked above and is the more specific answer: component resistances, connector positions and part numbers differ by family and belong there.
