The short answer
A dishwasher that will not start splits cleanly in two: either the machine has no power and the panel is dead, or the panel lights up and the machine still refuses to go. The second is far commoner and it is usually a latch or a lock. Press any button. A response of any kind — a beep, a light, a display — means the machine has power, and the fault is in what it is waiting for. On a Summit dishwasher the cause that ranks first is door latch not making, or the latch switch worn.
What you observe
- The panel lights up but pressing start does nothing — Power is present; the machine is waiting on a permission it has not been given.
- The panel is completely dead, with no lights and no beep — Power is not reaching the control at all.
- NEAR MISS — the machine starts and then stops partway through — That is a cycle fault, not a start fault, and it points at fill, drain or heat.
Causes, most likely first on a Summit dishwasher
- Door latch not making, or the latch switch worn — The control will not energise anything until the latch tells it the door is shut, and a worn hook or a tired switch stops that signal without stopping the panel. It ranks first on a Summit dishwasher because there is very little slack behind the panels of a compact cabinet, so anything that restricts restricts completely.
- Control lock or delay start left engaged — A lock icon, a child lock or a delayed start swallows every press and gives no warning beyond a small symbol. Second on this platform: it costs nothing to rule out and it is the cause that embarrasses people most often.
- No power at the outlet, or a tripped breaker — The machine is wired to a socket under the sink or a switched spur that has been turned off, or the circuit has tripped and nobody looked. Last, and the reason to work down the list rather than guess: a dead panel means the fault is upstream of the machine, and that is cheap to check.
Check in this order, and why
- Open and shut the door firmly and listen for the latch click — A soft or silent latch is the answer before anything else is tried.
- Look for a lock or clock symbol on the display and hold the marked button — Most machines clear a lock by holding one key for a few seconds.
- Check the panel is dead, then check the breaker and any switched spur — A dead panel and a live socket are two different faults.
What an owner can safely check
- Close the door with deliberate pressure and press start again — Clean the latch hook and the striker plate if the click is soft.
Tools: clothAbout 5 min
- Hold the key marked with a lock or a clock until the symbol clears, then press start — The manual names the key; on most machines it is the one on the far right.
About 5 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins, whatever the ranking above says.
Before you open anything
Safety
Unplug the machine or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Never tape, wedge or otherwise defeat the door latch to make the machine run: it is an interlock and it is there to stop the machine filling with the door open.
When to call a technician
Call when the panel is confirmed live, the latch clicks, no lock is showing and the machine still will not begin — at that point the next test is a meter on live terminals. On a compact machine, expect access to be the larger half of any labour quote — the part itself is rarely the expensive part.

What this page does not cover
This page is written for the Summit dishwasher as a class, not for one family or model line. Where a family- or model-specific page exists for your unit it is linked above, it is the more specific answer, and it is the one to read first. Deliberately not here: part numbers, wiring colours, panel removal order and torque figures, all of which differ between families under the same nameplate.
