Stuck key detected in keypad or keypad connection (Start/Resume or Cancel key stuck alerts customer; other stuck keys are recorded but ignored).

First step from the service manual

Check responsiveness of each key. Unplug dishwasher, disassemble door and inspect for correct assembly of control, console and button tree. Adjust assembly to eliminate stuck keys.

What 1-1 means on a Whirlpool dishwasher

Error code 1-1 on a Whirlpool dishwasher indicates the control board has detected that the K2 pilot relay is stuck in the closed position. A relay stuck closed means it is continuously passing current even when the control has not commanded it to activate. This fault is significant because it means one or more of the electrical loads controlled by the K2 pilot relay may be receiving unintended power, which can cause components to run out of sequence or overheat. The control board logs this code when it reads the relay output as active during a period when it should be open.

For homeowners, think of the K2 pilot relay as a switch inside the control board that is supposed to turn specific components on and off on command. When this switch gets stuck in the 'on' position, the dishwasher's brain detects a conflict between what it ordered and what is actually happening, and it shuts down to prevent damage.

This fault is triggered either by a failed relay on the control board itself or by a short circuit in the wiring or components connected to the K2 relay. Because the stuck-closed condition can result from either the relay or a downstream load failure, both the control board and all connected components must be inspected before replacement.

Common causes of 1-1

  1. 01

    Short circuit in a load connected to the K2 pilot relay

    Part replacement

    A shorted component or wiring harness connected to the K2 relay can force the relay output to appear continuously active. This is the first thing to rule out, as replacing only the control board without fixing the short will cause the new board to fail as well.

  2. 02

    Failed K2 pilot relay on the control board

    Part replacement

    The relay itself can fail mechanically or electrically in the closed position, meaning it passes current regardless of the control signal. This requires replacing the control board since the relay is integrated into the board assembly.

  3. 03

    Damaged wiring harness between control board and K2 relay loads

    Part replacement

    Chafed, pinched, or burnt wiring between the control board and the components it powers through the K2 relay can create an unintended current path that mimics a stuck-closed relay. Inspecting the full harness routing is necessary to rule this out.

Frequently asked questions about 1-1

What does error code 1-1 mean on a Whirlpool dishwasher?
Error code 1-1 means the control board has detected that the K2 pilot relay is stuck closed, meaning the relay is passing current when it should be off. The control board monitors its own relay outputs and flags this code when it detects a mismatch. The fault can originate in the relay itself or in a shorted component connected to it.
Is it safe to use my Whirlpool dishwasher with error code 1-1 active?
No, you should not continue using the dishwasher while error code 1-1 is active. A relay stuck closed means one or more components may be receiving unintended power, which creates a risk of overheating or further electrical damage. Keep the dishwasher unplugged until the fault is diagnosed and repaired.
How do I fix error code 1-1 on a Whirlpool dishwasher?
Start by unplugging the dishwasher or shutting off the circuit breaker. Then check all electrical loads connected to the K2 pilot relay for short circuits using a multimeter. If a shorted component is found, replace it. If no short is found in the loads or wiring, replace the control board. Always replace all shorted components alongside the control board, or the new board may fail immediately.
How much does it cost to repair error code 1-1 on a Whirlpool dishwasher?
A replacement Whirlpool dishwasher control board typically costs between $100 and $250 for the part alone, depending on the model. If a technician performs the repair, expect an additional $100 to $200 in labor. If the fault is caused by a shorted downstream component such as a pump or valve, that part will add to the total cost. A DIY repair is feasible if you are comfortable working with appliance wiring and a multimeter.
Can a shorted component cause error code 1-1, or is it always the control board?
A shorted load connected to the K2 pilot relay can directly cause error code 1-1 and is actually the first thing to check before replacing the control board. If you replace the control board without finding and fixing the short, the new board will likely fail in the same way. Use a multimeter to check resistance across each component powered by the K2 relay before ordering parts.
