Kitchenaid Dishwasher won’t start
KitchenAid Dishwasher Thermal Fuse
The thermal fuse shuts off power to the dishwasher if it overheats. If the thermal fuse blows, it will prevent the dishwasher from starting. To determine if the thermal fuse is defective, use a multimeter to test the fuse for continuity. If the thermal fuse does not have continuity, replace it.
KitchenAid Dishwasher Door Switch
The door switch prevents the dishwasher from running while the door is open. If the door switch is defective, the switch will prevent the dishwasher from running even when the door is closed. To determine if the door switch is at fault, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace it.
KitchenAid Dishwasher Wire Harness
If the dishwasher start button appears to work, but the dishwasher still won’t start, a wire harness which sends power from the control board to the pump components could be damaged. Inspect the wire harness for any frayed or broken wires and replace if necessary.
KitchenAid Dishwasher Door Latch
The door latch ensures that the dishwasher door latches shut. If the door does not latch properly, the door switch might prevent the dishwasher from running. If the door latch is broken, replace it.
KitchenAid Dishwasher Main Control Board
The main control board provides power to nearly every component of the dishwasher. If there is a problem with the main control board, it might not send voltage to the dishwasher, causing the dishwasher not to start. Control boards are often misdiagnosed—make sure you check more commonly defective parts before replacing the main control board.
KitchenAid Dishwasher Drain Pump
A dishwasher drain pump assists in removing the water from the tank at various times during operation. Since the unit will drain some water from the tank prior to the fill cycle beginning, a faulty drain pump unable to drain any water could prevent the dishwasher from starting.
KitchenAid Dishwasher Touchpad and Control Panel
To determine if the touchpad is at fault, try pressing various buttons on the touchpad. If some of the buttons don’t respond, the touchpad might be defective. (Some manufacturers sell the touchpad separately from the control panel. Other manufacturers require that you purchase the touchpad and control panel together. If you cannot replace the touchpad individually, replace the touchpad and control panel.)
KitchenAid Dishwasher Touchpad
To determine if the touchpad is at fault, try pressing various buttons on the touchpad. If some of the buttons don’t respond, the touchpad might be defective. If the touchpad isn’t working properly, replace it. (Some manufacturers sell the touchpad separately from the control panel. Other manufacturers require that you purchase the touchpad and control panel together. If you cannot replace the touchpad individually, replace the touchpad and control panel.)
Incoming Power Problem
If there are no indicator lights or any noise from the dishwasher when it is turned on, it is likely that power is not reaching the dishwasher. Check the circuit breakers and GFCI (ground-fault circuit interrupter) outlets, if applicable, to confirm they have not tripped, or inspect any fuses to confirm none have blown. Since most dishwashers are hardwired (not plugged in) the junction box on the dishwasher should be checked for loose or burnt wires.
KitchenAid Dishwasher Pump and Motor Assembly
A defective dishwasher pump and motor assembly may prevent the appliance from starting. Make sure that power is getting to the circulation pump and motor. If power is getting to the pump and motor assembly but it still won’t run, replace the pump and motor assembly.
KitchenAid Dishwasher Control Board
A dishwasher’s control board provides power to nearly every electrical component in the dishwasher. A faulty board may be unable to supply power to the electrical components or respond to the touchpad buttons being pressed, which can prevent dishwasher from starting.
KitchenAid Dishwasher Timer
The timer allows power to flow to the proper parts at the proper times. If the timer isn’t working properly, it might not send voltage to the dishwasher, causing it not to start. Timers are often misdiagnosed—make sure you check more commonly defective parts before replacing the timer.
KitchenAid Dishwasher Circulation Pump
A defective dishwasher circulation pump may prevent the appliance from starting. Make sure that power is getting to the circulation pump and motor. If power is getting to the circulation pump but it still won’t run, replace the component.
KitchenAid Dishwasher User Control and Display Board
A dishwasher’s user control and display board allows the user to select a wash and drying cycle and start the appliance. If the start button won’t work, it’s likely the user control and display board is malfunctioning and will need to be replaced with a new one.
