What this usually means here
On this platform a machine that will not start is usually being held by its own door latch: the door looks shut, the switch disagrees, and nothing happens. What puts it first on this machine: nothing in this machine compensates for a poor installation. The checks below follow that ranking, and the first need no tools.
What you observe
- The panel lights, the cycle is selected and pressing start does nothing — A live panel with a dead start is a latch question far more often than a control one.
- No lights, no sounds and no response to any button — A dark panel is a supply question until the supply is proven.
- An indicator or a delay time is showing that nobody set deliberately — An unrecognised indicator is the commonest form this takes.
- NEAR MISS — it starts and stops after a minute — That is a fill or a drain fault rather than a start fault, and it belongs on the drainage page.
Causes, most likely first on this platform
- A door latch that is not confirming closed — A dishwasher will not run unless its latch reports closed. A door that has dropped, a catch out of adjustment or a rack corner holding the door a fraction proud stops a perfectly healthy machine from starting. First, and not narrowly — nothing in this machine compensates for a poor installation.
- Power not reaching the machine — A built-in dishwasher is usually wired to a switched spur or a socket inside an adjacent cabinet, and nobody remembers it is there. A tripped breaker or a switched-off spur gives a completely dead machine. It ranks second here: nothing in this machine compensates for a poor installation.
- A control lock, a delay start or a cycle left paused — A control lock, a delayed start or a cycle paused and never resumed produces a machine that lights up and refuses to run. It is a setting rather than a fault and it is ruled out in seconds. Third: real on this platform, and behind two causes that cost less to rule out.
Check in this order, and why
- Push the door firmly shut and listen for the latch, and check no rack corner is holding it — It tests the most likely cause in seconds and needs nothing at all.
- Check the breaker and any switched spur or socket serving the machine — Free, fast, and the answer often enough to sit near the top.
- Hold the lock button for several seconds and cancel any delay or programme — Seconds to do, and it is the whole answer often enough to try first.
What an owner can safely check
- Clean the latch and the strike, push the racks fully in and close the door firmly — A rack corner or a tall handle holding the door a fraction proud is the commonest version of this.
Tools: clothAbout 15 min
- Cycle the breaker fully off and on, and check the switched spur under the sink — The switch is often behind a cabinet door beside the machine and gets knocked during cleaning.
About 15 min
- Cancel the programme completely, clear any lock or delay and start a short cycle — A full cancel rather than a pause is what clears a stuck sequence.
About 10 min
- STOP at the first step needing a meter on live terminals or a sealed panel off — That is where owner checks end. Write down what came back clean: a technician who knows that spends the visit fixing rather than repeating it.
Before you open anything
Safety
Switch the dishwasher off at its breaker and shut the supply stop valve before reaching into the sump or disconnecting a hose — a capacitor can hold a charge after the power is off. Expect sharp objects in the sump: broken glass and staples end up there. Never disable the door latch to watch a cycle run.
When to call a technician
Call when the fault needs a meter on a door switch, a thermal fuse or a control board, and call when the machine is dead with a confirmed live supply. The other line is a machine that has tripped a breaker: that is an electrical fault rather than a start fault, and it is not something to reset repeatedly.

What this page does not cover
This is generalized information for the RCA dishwasher as a class, not for one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer, it is linked among the pages above, and it supersedes this one wherever the two differ. Not covered here: part numbers, switch positions, control-board detail and the disassembly order, all of which differ by family and belong on the page for that family.
