KitchenAid Dishwasher Not Starting: 7 Fixes

Common Symptoms

• Dishwasher doesn't respond when the Start button is pressed
• Control panel is completely dark — no lights at all
• Control panel lights up but cycle won't begin after pressing Start
• Door appears closed but dishwasher still won't start
• Control Lock LED is illuminated on the panel
• Display shows a countdown timer but machine doesn't run immediately
• Dishwasher was working yesterday and is completely dead today

Most Likely Causes

1. 1

   Control Lock (Child Lock) Activated

   All KitchenAid dishwashers in the KDTM354, KDPE234, KDFE104, and KDTE254 series have a Control Lock feature that disables all buttons to prevent accidental cycle starts. When active, a lock icon or 'LOC' indicator illuminates on the panel. It is activated — and deactivated — by pressing and holding the same button (usually labeled 'Control Lock' or a lock icon) for 3 seconds. This is the most frequently overlooked cause of a 'dead' dishwasher.

2. 2

   Door Latch Assembly Not Engaging (WPW10195417)

   KitchenAid dishwashers have a door latch and door switch assembly (WPW10195417) that must both mechanically latch and electrically signal 'door closed' before the control board will allow a cycle to start. If the latch is worn, cracked, or misaligned, the door may appear closed without completing the electrical circuit. The door switch can be tested for continuity — a switch that reads open when the door is fully closed needs replacement.

3. 3

   Delay Start Accidentally Activated

   The Delay Start feature queues the dishwasher to run hours later — 2 to 12 hours depending on the model. If this was pressed inadvertently, the display shows a countdown number and the machine will not start until that time elapses. Pressing Cancel clears the delay and returns the dishwasher to standby mode, ready for an immediate start.

4. 4

   Blown Thermal Fuse (WPW10258275)

   The thermal fuse (WPW10258275) is a one-time safety cutout that opens if the dishwasher's control circuit overheats. Once blown, it breaks the power path to the control board — the panel may be completely dark or may power on briefly then go dead. A blown thermal fuse tests open (OL) on a multimeter set to continuity or resistance mode. Unlike a circuit breaker, it does not reset — it must be replaced.

5. 5

   Tripped GFCI Outlet or Circuit Breaker

   Many kitchen dishwashers are wired to a GFCI-protected circuit or plugged into a GFCI outlet under the sink. A nuisance trip — triggered by a water splash, ground fault, or power surge — cuts all power to the dishwasher. The outlet reset button under the sink is easy to miss. Similarly, the dedicated 15- or 20-amp breaker in the electrical panel may have tripped to the middle position, appearing 'on' while actually interrupting the circuit.

6. 6

   Failed Control Board

   The main control board processes all button inputs and sequences the wash cycle. A failed board may produce a completely dark panel, frozen display, or buttons that register presses but never start a cycle. Control board failures are usually preceded by other erratic behavior — random cycle interruptions, unresponsive buttons, or error codes. It is the most expensive diagnosis and should only be reached after all other causes are eliminated.

Quick DIY Checks

1. 1Check the Control Lock first: look for a lock icon or 'LOC' text on the display or panel. On KDTM354 and KDTE254 models, press and hold the 'Control Lock' button for 3 seconds until the indicator goes out. On KDFE104 and KDPE234 models, the lock button may be shared with another function — hold it 3 seconds. Once disabled, try pressing Start. If the lock engages unintentionally during normal use, the button may be sticking — clean around it with a dry cloth.
2. 2Check the GFCI outlet under the sink: open the cabinet under the kitchen sink. Locate any GFCI outlets on the back wall (rectangular outlets with TEST and RESET buttons). Press RESET firmly — it should click in if it was tripped. Also go to your electrical panel and find the breaker labeled 'Dishwasher' or 'Kitchen.' If it has flipped to the center position, push it fully to OFF then firmly back to ON. Return to the dishwasher and try starting a cycle.
3. 3Cancel any active Delay Start: press and hold the Cancel/Drain button for 3 seconds. The display countdown will clear. Press Start to begin an immediate cycle. If the dishwasher starts normally after canceling the delay, the Delay Start button was pressed by accident — note its location on the panel to avoid future accidental presses.
