What 24 means on a Maytag washer

Error code 24 on a Maytag washer indicates the control board has detected an incorrect rotary switch position. The rotary switch, sometimes called the cycle selector switch, sends positional signals to the main control board to communicate which wash cycle or setting the user has selected. When the board receives a signal that does not match any valid or expected switch position, it throws code 24 and halts operation to prevent running an unintended cycle.

For a homeowner, this means the washer's main control is seeing a signal from the cycle selection dial or switch that it does not recognize. This can happen because the switch itself has failed internally, because the wiring connecting it to the control board is damaged or loose, or because the switch is physically stuck between positions. The machine is not able to proceed because it does not know which cycle to run.

This code is not related to water, draining, or motor function. The issue is entirely within the cycle selection input system. Resolving it typically requires inspecting the rotary switch, its wiring harness, and potentially the main control board if the switch and wiring check out as intact.

Common causes of 24

  1. 01

    Failed or worn rotary cycle selector switch

    Part replacement

    Internal contacts inside the rotary switch can wear out or fail, causing it to send an invalid or out-of-range signal to the control board. This is the most common source of code 24 and typically requires replacing the switch assembly.

  2. 02

    Switch positioned between cycle settings

    Wiring / connection

    If the rotary knob is resting between two detent positions rather than fully seated in one, the control board receives an ambiguous signal and triggers code 24. Firmly turning the knob to a defined cycle position can resolve this without any parts.

  3. 03

    Loose or damaged wiring harness to the rotary switch

    Wiring / connection

    A wiring harness connector that has vibrated loose or wires that have become frayed or shorted can cause the control board to receive an incorrect positional reading from the switch. Inspecting and reseating or repairing the harness may clear the code.

  4. 04

    Faulty main control board

    Part replacement

    If the rotary switch and its wiring both test correctly, the main control board itself may be misreading the switch input signal due to a failed input circuit on the board. Board replacement is required in this scenario.

Frequently asked questions about 24

What does error code 24 mean on a Maytag washer?
Error code 24 means the control board detected an incorrect or unrecognized position signal from the rotary cycle selector switch. The machine cannot determine which cycle to run, so it stops and displays the code. The problem is in the cycle selection input system, not in the motor, water valves, or drain system.
How do I fix error code 24 on a Maytag washer?
Start by turning the cycle selector knob firmly to a defined setting to make sure it is not caught between positions. If the code persists, unplug the washer and inspect the wiring harness connector at the rotary switch for loose pins or visible damage. If the harness looks intact, the rotary switch itself likely needs to be replaced. If a new switch does not clear the code, the main control board should be tested or replaced.
Can I still use my Maytag washer while error code 24 is showing?
No, the washer will not run a cycle while code 24 is active because the control board cannot identify a valid cycle selection. Running the machine in this state is not possible under normal operation. You need to resolve the rotary switch issue before the washer will accept a start command.
How much does it cost to repair Maytag washer error code 24?
If the fix is simply repositioning the knob, there is no cost. A replacement rotary cycle selector switch typically costs between $20 and $60 for the part, and replacing it is a low-to-moderate difficulty repair that most mechanically comfortable homeowners can do with basic tools. If the main control board is the cause, board costs generally range from $100 to $250, and professional labor adds another $80 to $150 depending on your area.
Is error code 24 on a Maytag washer a serious problem?
Code 24 does block the washer from running, but it does not indicate damage to the motor, tub, or any high-cost mechanical component. In most cases the rotary switch or its wiring is the cause, both of which are relatively inexpensive repairs. Addressing it promptly prevents the inconvenience of a non-functional machine, but there is no risk of additional damage from leaving it unrepaired while you source parts.
