The short answer
This code pairs a machine that will not run with an indicator above a key flashing rapidly and continuously. A rapid, continuous flash is a deliberate signal rather than a malfunction of the light — the console is telling you which function it is unhappy about, and the key underneath the flashing indicator is the thing to look at.
Whirlpool dishwasher code as the manufacturer publishes it
Reference| Code | Meaning |
|---|---|
| 2-1 | Won't Run and LED Above Key is Flashing Rapidly and Continuously. |
What you observe alongside the code
- An indicator above one key flashing fast and continuously — A deliberate signal about that function.
- The machine will not start a cycle — Whatever the indicator is about, it is blocking the start.
- Other indicators behaving normally — Confirms the console itself is working.
- It follows a cycle that was cancelled or interrupted — A common trigger for a state the machine will not leave.
What triggers it, most likely first
- A function or option that cannot be honoured — First: the console is flagging the specific thing it cannot do, which is why the key it sits above matters.
- A control lock or a child lock engaged — Second: it blocks the start and it flashes to say so, and it is free to release.
- A door that is not fully latched — Third: the machine will not run without the latch made, and the console commonly signals that at the start key.
- A latched fault from an interrupted cycle — Last: a power cycle at the breaker clears this class of state.
Check in this order, and why
- Note which key the flashing indicator sits above — It names the function the machine is objecting to.
- Check the door is fully latched and the lock is off — Two free causes, both common.
- Cut power at the breaker for a minute and restore it — Clears a latched state from an interrupted cycle.
- Try starting a different, simpler cycle — It tells you whether one option is the problem.
Clearing the code, then the owner-safe checks
- Push the door firmly shut until the latch engages — A rack pushed out slightly is enough to hold it off.
About 5 min
- Release any control or child lock — Usually a held press; check your use guide for the gesture.
About 5 min
- Switch the breaker off for a minute, then on, and retry — Clears the interrupted-cycle case.
About 10 min
- STOP HERE if the same indicator flashes on a simple cycle with the door latched — That is the control or the function it is flagging.
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 properly, no lock is set, a power cycle has been tried, and the same indicator still flashes on the simplest cycle you can select. Nothing is at risk in the meantime: the machine is refusing to start rather than doing something unsafe, so this can wait for a convenient appointment.

Which model lines this reading applies to
This reading of 2-1 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. Flash rates and their meanings differ by console generation on this platform, so the interpretation belongs to your own use guide. 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.
