Unplug it, then read this
Unplug it and stop running cycles. On a plug-in countertop machine the single most useful test is to move it to a protected receptacle on a different circuit: if the trip follows the machine, the machine is at fault, and if it stays behind, the wiring is. Everything else on this page is about how to read that answer.
What is happening
- The protected receptacle trips whenever the machine runs — A real fault to earth somewhere, and the timing narrows it.
- The plug or its face is warm, pitted or discoloured — A poor connection heating up. This one does not wait.
- A hot-plastic smell from the machine or the outlet — Something is overheating right now. Unplug it.
- The counter circuit trips when the kettle is also on — Overload, not a fault. Nothing inside is broken.
- NEAR MISS - it trips only when the faucet adapter sprays back — Water reaching the panel - a plumbing fix with an electrical symptom.
Causes, ranked for a plug-in countertop machine
- A wet or damaged plug and cord at the counter — First on this form factor: the plug lives at counter height beside a sink, the wettest place in the kitchen, and the cord is coiled and moved constantly.
- A shared counter circuit under load — Second, and not a fault at all - a heated appliance plus a kettle on one circuit trips it honestly.
- Water reaching the control panel — Third. The faucet adapter and fill hose sit above the panel, and a loose adapter sprays back across it.
- Heating element shorting to the tub — Fourth, and the classic same-stage trip, because the element runs only during heat and dry.
- House wiring rather than the appliance — Last, and the reason the swap test comes first - it is the one cause repairing the machine cannot fix.
The order, and why the swap comes first
- Unplug, then test and reset the receptacle alone — If it will not hold with the machine out, stop - the problem is the wiring.
- Move the machine to a different protected outlet — One move that separates appliance from house, which no other test on this list does.
- Inspect the plug and cord — The top-ranked cause, and visible without opening anything.
- Note the cycle stage of any trip — It is the only clue that distinguishes the element from the panel.
What you can do, and where it stops
- Unplug the machine at once — Before any inspection, and leave it unplugged between tests.
About 5 min
- Reset the receptacle with nothing plugged into it — A device that will not hold on its own has answered the question already.
About 5 min
- Dry and examine the plug and the full cord — Look for pitting on the pins, browning on the face, splits along the cord.
Tools: torch, dry clothAbout 15 min
- Run one cycle on a different protected outlet, on another circuit — Stay with it. If it trips there too, the fault is inside the machine.
About 60 min
- Write down the stage at which it trips — Fill, wash, heat or dry, and whether it is the same stage each time.
About 5 min
- STOP - do not open the panel or the back of the machine — The element terminals and panel wiring are behind them, with no safe owner test.
The rules that are not negotiable here
Safety
Unplug the appliance or switch off its breaker before removing any panel - a capacitor can hold a charge after the power is off. Never use an extension cord, a power strip or a ground-defeating adapter with a heated appliance, and never bypass a protective device that keeps tripping: it is doing the job it exists for. A US household branch circuit is 15 A or 20 A at 120 V, and kitchen counter circuits are shared. If you smell gas: do not switch anything on or off, leave the building, and call the gas utility or 911 from outside.
Who to call, and which one
Call an electrician, not an appliance technician, if the receptacle will not hold with the machine unplugged, or if it trips on every outlet in the kitchen. Call an appliance technician when the fault follows the machine to a second circuit, or when the trip lands at the same cycle stage each time. Stop using it entirely if there is browning at the plug, melted plastic or any burning smell - past that point, testing tells you nothing useful.

The limits of a generalized page
This is generalized information across the dishwashers sold under this nameplate - countertop, portable and built-in machines with different supply arrangements. Where a family- or model-specific page exists for your unit it is the more specific answer and is linked here. Deliberately absent: element ratings, terminal layouts, the current your machine draws, and any instruction involving a meter.
