Control suspects door switch is stuck closed; control looks for the door switch to open between cycles; customer didn't open door between cycles; door switch contacts stuck closed.

First step from the service manual

1. Open and close door and then press Start/Resume key. Instruct customer. 2. Unplug dishwasher or disconnect power. 3. Measure resistance of door switch contacts while checking mechanical operation of latch assembly.

What 5-2 means on a Kenmore dishwasher

The 5-2 error code on a Kenmore dishwasher indicates the control board has detected that the door switch contacts appear to be stuck in the closed position. The control is programmed to block a new cycle from starting under this condition because it cannot confirm the door was opened and properly re-latched between uses. Technically, the control monitors the door switch circuit continuously and flags 5-2 when the switch never transitions to open, either because the user skipped opening the door between consecutive cycles or because the switch contacts have physically welded or corroded closed.

For homeowners, this error typically means one of two things: either you started a new cycle without opening the dishwasher door after the previous cycle ended, or the door latch switch itself has a mechanical or electrical fault. The dishwasher is designed to see the door open at some point between cycles as a confirmation that everything is working normally. If it never sees that transition, it refuses to run as a precaution.

The first thing to try is simply opening the door fully, closing it again firmly, and pressing the Start or Resume key. If the dishwasher starts normally, the fix is a habit change: open the door between every cycle. If the error returns or the dishwasher will not start after that step, the door latch assembly and switch contacts need to be inspected and tested with a multimeter to determine whether the switch itself has failed mechanically or electrically.

Common causes of 5-2

  1. 01

    User did not open door between cycles

    Wiring / connection

    The most common trigger for 5-2 is simply running a new cycle immediately after the previous one without opening the door. The control board never sees the switch transition to open and flags the error as a precaution.

  2. 02

    Door switch contacts stuck closed

    Part replacement

    The door switch contacts can weld together or corrode in a way that keeps the circuit permanently closed, making the control board unable to detect when the door is actually open. This will cause 5-2 even when the user does open the door between cycles.

  3. 03

    Faulty door latch assembly

    Part replacement

    The mechanical latch assembly can wear or break in a way that prevents the switch actuator from releasing properly, keeping the switch contacts closed even when the door appears unlatched. Physical inspection of latch travel and switch actuation is needed to confirm this.

  4. 04

    Wiring fault in door switch circuit

    Wiring / connection

    A short in the wiring harness between the door switch and the control board can hold the circuit in a closed state regardless of switch position, mimicking a stuck-closed switch and triggering the 5-2 code.

Frequently asked questions about 5-2

What does error code 5-2 mean on a Kenmore dishwasher?
Error code 5-2 means the control board detected that the door switch contacts never transitioned to open, so it suspects the switch is stuck closed. This happens either because the door was not opened between cycles or because the door switch or latch assembly has a fault. The dishwasher blocks the next cycle from starting until the condition is resolved.
How do I fix error code 5-2 on my Kenmore dishwasher?
Start by opening the door completely, closing it firmly, and pressing the Start or Resume key. If the dishwasher runs normally, make it a habit to open the door after every completed cycle before starting a new one. If 5-2 returns after doing this, use a multimeter to measure resistance across the door switch contacts while manually working the latch to confirm the switch is releasing and closing correctly. A switch that reads continuity with the door open needs to be replaced.
Can I still use my Kenmore dishwasher when code 5-2 is showing?
The dishwasher will not start a cycle while 5-2 is active, so normal use is blocked until the condition is cleared. If opening and closing the door clears the code and the machine runs, it is safe to continue using it. If the code is caused by a faulty switch that stays closed, the dishwasher should not be forced into operation by bypassing the error, as the control uses the door switch for safety interlocking during the cycle.
How much does it cost to fix a Kenmore dishwasher 5-2 error code?
If the fix is simply opening the door between cycles, it costs nothing. If the door switch has failed and needs replacement, the part typically costs between $15 and $40 depending on the model. Replacing a door switch is a moderately easy repair accessible from inside the door panel; most homeowners comfortable with basic appliance repair can complete it in under an hour. If the entire latch assembly needs replacement, parts run $25 to $70, and labor from a technician typically adds $80 to $150.
How do I test the door switch on a Kenmore dishwasher showing a 5-2 error?
Disconnect power to the dishwasher before testing. Access the door switch, which is located inside the door panel near the latch mechanism. Set a multimeter to the resistance or continuity setting and probe the switch terminals. With the door open and the latch released, the switch should read open circuit. With the door closed and the latch engaged, it should read closed circuit or near-zero ohms. If the switch reads closed in both positions, the contacts are stuck and the switch needs to be replaced.
