One of the keys (buttons) is stuck closed (active).

Mabe codesMabe dryer codes

One of the keys (buttons) is stuck closed (active).

First step from the service manual

Enter function test mode and perform key (button) test to determine which button is at fault. Carefully free the key and perform the test again. If button is free but the key stuck code still exists, replace electronic control.

What E68 means on a Mabe dryer

Error code E68 on a Mabe dryer indicates that one or more buttons on the control panel has been detected in a continuously closed (active) state. The electronic control board monitors each button input and expects a momentary signal when a key is pressed. When a button remains in the closed position without being actively pressed by the user, the control interprets this as a stuck key condition and triggers the E68 fault to prevent unintended operation of the dryer.

The most common cause of this fault is physical debris, moisture, or residue that has worked its way beneath a control panel button, holding the contact in a closed position. Over time, detergent residue, lint, or cleaning product buildup can accumulate around buttons and cause them to bind. In some cases, a button cap or actuator may be physically warped or damaged, preventing it from returning to its neutral position after being pressed.

If the physical button appears free and unobstructed but the E68 code persists, the fault has shifted from a mechanical issue to an electrical one. The internal switch contact beneath the button may have welded closed or failed in the closed position, or the control board itself may be misreading the input signal due to a component failure on the board. In this scenario, replacing the electronic control board is the required repair, as the fault cannot be resolved through cleaning or mechanical adjustment alone.

Common causes of E68

  1. 01

    Debris or residue beneath a button

    Wiring / connection

    Lint, detergent residue, or cleaning product buildup can accumulate under a button and hold its contact in the closed position. Inspect each button for visible sticking, unusual resistance, or failure to spring back when pressed.

  2. 02

    Physically stuck or damaged button cap

    Part replacement

    A button cap or actuator that is warped, cracked, or misaligned may not return to its resting position after being pressed. Carefully examine each button visually and test each one individually for proper travel and return.

  3. 03

    Failed internal switch contact

    Part replacement

    The switch contact beneath a button can fail in the closed position even when the external button cap moves freely. This type of internal contact failure requires replacement of the electronic control board.

  4. 04

    Moisture intrusion into the control panel

    Wiring / connection

    Moisture from spills or high-humidity environments can bridge switch contacts and simulate a stuck key condition. If moisture is suspected, allow the panel to dry fully before retesting.

  5. 05

    Electronic control board failure

    Part replacement

    If all buttons appear physically free and unobstructed but the E68 code remains after the button test, the control board is misreading the input signal. Replacing the electronic control board is necessary to resolve the fault.

Frequently asked questions about E68

What does E68 mean on a Mabe dryer?
E68 means the dryer's electronic control has detected that one of the control panel buttons is stuck in the closed or active position. The control monitors each button for momentary input and flags E68 when a button appears continuously pressed without user interaction. The fault can be caused by physical debris under a button or by an internal switch or control board failure.
Can I fix the E68 error myself without replacing any parts?
Yes, in many cases this is possible. Start by entering the dryer's function test mode and running the key test to identify which button is at fault. Carefully inspect that button for debris, residue, or sticking, and clean around it to free the contact. If the button moves freely and the error clears after retesting, no parts are needed.
Will resetting the dryer clear the E68 error code?
A reset may temporarily clear the E68 code, but it will return if the underlying cause is not corrected. If a button is physically stuck or an internal switch contact has failed, the fault condition still exists and the code will reappear when the control re-detects the stuck input. The root cause must be resolved to permanently clear the error.
Is it safe to use my Mabe dryer while the E68 code is active?
It is not recommended to continue operating the dryer with an active E68 fault. A stuck button could cause unintended program selections or prevent the control from responding correctly to user input. Diagnosing and resolving the fault before resuming normal use is the safer course of action.
How much does it cost to repair the E68 error on a Mabe dryer?
If the issue is only a stuck button that can be freed by cleaning, the repair may cost little to nothing beyond your time. If the electronic control board needs to be replaced, costs typically range from $150 to $350 depending on parts and labor rates in your area. Getting a diagnosis first will help clarify which repair is actually needed before committing to a part purchase.
