Quick answer: A dishwasher that’s gone completely dead — no lights, or lights but nothing happens when you press start — is usually the door lock switch, not a dead machine. A repairer charges $100–165 just to attend and diagnose, before any parts, and most dishwasher repairs land at $200–420 all up. The switch itself is commonly a $34–77 part and a two-screw swap behind the inner door. Rule out power, child lock and delay start first, then look at the door switch — and you keep most of the cost.

First, rule out the free stuff
Before you order anything, spend two minutes ruling out the faults that cost nothing to fix.
- Power. Check the wall socket and the isolating switch (often in the cupboard under the sink). Test the socket with something else — a phone charger or the kettle — and check the switchboard for a tripped breaker or safety switch.
- Child lock / control lock. Most machines have one, usually shown by a padlock symbol. Hold the marked button (often about 3 seconds) until the light clears, then try again.
- Delay start. It’s easy to bump the delay button — the machine looks off but is quietly counting down. Cancel any delay and restart.
- The door isn’t fully shut. Give it a firm push until it clicks. Check nothing’s in the way — a tall pot handle, or a rack pushed out just far enough to stop the latch seating.
If it still won’t start, the odds swing hard toward one cheap part.
The usual culprit: the door lock switch
Your dishwasher won’t run a drop of water until a small microswitch inside the door confirms it’s properly shut — a safety interlock, so no closed door means no cycle. When that switch (or the plastic latch that trips it) wears out, you get the classic “dead” symptoms: press start and nothing happens, the lights don’t change, or it beeps and refuses. The machine is fine — it just never got the “door closed” signal.
The tell-tale is the latch: if the door feels loose when it should click firmly, or the latch moves but the machine won’t wake up, the door lock switch is the prime suspect — the most common reason a dishwasher goes dead, and one of the cheapest parts in it.

The two-screw, two-minute fix
This is one of the friendliest repairs on any appliance. The door switch sits right behind the inner door panel, usually held by two screws — no tilting the machine, no plumbing.
- Isolate the power. Switch off at the wall and pull the plug (or flick the isolating switch under the sink). If your dishwasher is hard-wired rather than on a plug, treat it as a mains job — see the safety note below.
- Open the door and undo the screws around the inner door panel, usually along the top edge near the latch. Ease the panel back just enough to reach the switch.
- Unclip the old switch. It’s held by two screws or clips. Note how the wiring plug sits — a quick photo on your phone makes reassembly foolproof — then unclip it.
- Fit the new switch, reconnect the plug, screw it back and refit the panel.
- Restore power and test — close the door, listen for the click and start a cycle.
Once the panel’s off it’s genuinely a couple of minutes of work. A door-latch swap on a plug-in machine is exactly the kind of low-risk job a confident home fixer can take on.
The money: a ~$35 part vs a $200-plus call-out
Here’s why this one stings if you outsource it. A repairer’s call-out or diagnostic fee is $100–165 just to walk in the door, before a single part or minute of labour — and many set a one-hour minimum, so a ten-minute swap is still billed as a full hour on top. All up, a booked dishwasher repair commonly runs $200–420.
The door lock switch itself is typically a $34–77 part. Do it yourself and you keep roughly 60–80% of what the repair would have cost. The kicker: when a tradie diagnoses “won’t start,” they’ll very often fit the same door switch you’d have ordered — so you’re mostly paying for the drive out and the screwdriver.
Weigh it against a whole new dishwasher and the maths is even more lopsided: a decent machine is many hundreds of dollars, sometimes replaced over a part that costs less than a takeaway dinner.
When it’s worth calling a licensed person
DIY is the right call for the plug-in door-switch swap above. A few situations aren’t:
- A hard-wired dishwasher. If yours is wired into the wall rather than plugged into a socket, disconnecting it is mains work that may legally require a licensed person in your state. Don’t open it up while it’s live.
- A new switch doesn’t fix it. If fitting the door switch doesn’t bring the machine back, the fault may be in the control board or wiring — worth a proper diagnosis rather than throwing parts at it.
- Any sign of water damage or burnt wiring around the door. Stop and get it looked at.
Once it’s starting again, if you find it runs but leaves water in the bottom, or comes out wet, those are separate — and usually cheap — faults. See our guides on a dishwasher that won’t drain and a dishwasher that won’t dry.
Frequently asked questions
Q: My dishwasher has power but won’t start — what’s the most likely cause?
A: After ruling out child lock and delay start, it’s most often the door lock switch. The machine won’t begin a cycle until that switch confirms the door is shut, so a worn switch or latch leaves it looking dead even though everything else works.
Q: How do I know it’s the door switch and not the control board?
A: The tell-tale is the latch — a loose or non-clicking door, or lights that never respond when you press start, point to the switch. It’s also the cheaper part by far, so it’s the sensible first swap. If a new switch doesn’t fix it, then look at the board.
Q: Is replacing a dishwasher door lock switch safe to do myself?
A: Yes, on a plug-in machine, as long as you switch off at the wall and unplug it first. It’s a two-screw part behind the inner door with no plumbing involved. If your dishwasher is hard-wired, treat it as a mains job that may need a licensed person.
Q: How much does it cost to fix a dishwasher that won’t start?
A: The door lock switch is commonly a $34–77 part. A repairer would charge $100–165 just to attend, with most full dishwasher repairs landing at $200–420 — so doing it yourself keeps most of the money in your pocket.
Q: The part isn’t listed for my brand — can you still help?
A: Yes. Check the model sticker inside the door rim, then send us the model number and we’ll check which door switch matches your machine.
Bottom line: a dead dishwasher is usually a two-screw, roughly $35 fix — not a new machine, and not a $200 call-out. Find the exact door switch for your model, match it to the number on your sticker, and have it running again this weekend.
