Kenmore Dishwasher Error Code 5-2

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.

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.

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.

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.

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.
