A dishwasher not turning on is a dark panel or a start press that the manual says should begin a cycle and does not. My dishwasher is not turning on and the dishwasher is not turning on are the same report. A dishwasher not starting is the name many manuals use for it. Why is my dishwasher not turning on is worth splitting before you pull the machine out. A dishwasher not turning on no power at the display points at the breaker, a tripped GFCI under the sink if one is actually there, or a door that is not latched. A lit display that ignores start is the control-lock page in that model's manual, or the latch.
Latch and control lock
Close the door until you hear or feel the latch the manual describes. A rack that is not pushed in will hold the door off the latch. Do not press the latch switch with a finger or a tool to make the machine run with the door open. That switch is there so the spray stays in the tub.
A dishwasher start button not working, with lights still on, is often a control lock. The steps are in the manual for the model on the door frame. There is no shared three-button code. Brand start sequences stay on that brand's own page later. Do not hold random keys.
Power, water, and a tub that is already full
Check the breaker once: off, then on. If it trips again, stop and call an electrician. Look for a GFCI only where you can see one, often under the sink, and reset it only if the floor and your hands are dry. Do not reset a breaker while you are standing in water.
If the tub is full, the dishwasher has been on. That is dishwasher not draining, not a dead start. If the floor is wet, use dishwasher leaking from the bottom and leave the start button alone. A cycle that finishes with wet dishes, and a display that works, is dishwasher not drying.
| What you see | Likely cause | Safe check |
|---|---|---|
| No lights, no sound | Breaker, GFCI, or latch | Dry floor. Breaker once. Latch the door |
| Lights on, start does nothing | Control lock or latch | The manual's lock steps for this model only |
| Tub full of water | Drain, not a dead machine | Use the drain guide |
| Water on the floor | Leak | Stop. Do not start a cycle |
| Breaker trips again | Electrical fault | Call an electrician |
Checks in order
Make sure the floor is dry
If it is wet, stop and use the leak guide. Do not kneel in water to reach a plug.
Latch the door
Racks in. Door fully closed. Do not bypass the latch.
Read the control lock
Use only the steps printed for this model. A start button that needs a press and hold is in that same section.
Reset the breaker once
Off, then on. A second trip is an electrician's job. Reset a visible GFCI only with dry hands.
Stop if the tub is full or the panel stays dead
A full tub is the drain guide. A panel that stays dark after the latch and one breaker reset needs a technician. Do not pull the dishwasher out to probe the junction box.
Questions readers ask
Why is my dishwasher not turning on if it worked yesterday?
The door may not be latched, a control lock may be on, or the breaker may be off. Check those before you assume the control failed. Use the manual's lock steps for this model only.
The start button lights up and nothing happens. Is that no power?
No. Lights mean some power is present. A dishwasher start button not working with the panel lit is the latch or the control lock in the manual, not a dark-house breaker.
There is water in the tub and the buttons are dead. What now?
Do not keep pressing start. If you can reach the breaker on a dry floor, shut it off. The standing water is the drain guide once power is safe. If the floor is wet, stop.
Can I start it with the door unlatched to see if the pump runs?
No. The latch is a safety switch. Defeating it puts spray outside the tub.
