Stop, then read this
Stop using the machine and switch off its breaker. Electrical symptoms on a built-in dishwasher are nearly always water reaching something it should not, and none of those improve with another cycle. The one useful thing to do before calling is to note at which stage of the programme the trip or the smell happens.
What you are dealing with
- The breaker trips at the same point every cycle — A real fault, and the timing names the circuit involved.
- A smell of hot plastic or an acrid smell near the door — Something is overheating. Stop; do not investigate mid-cycle.
- Browning, bubbling or char at the kick-plate connection box — A loose connection has been arcing, possibly for months.
- A tingle from the door or the front panel — Current on the casing. The most urgent item here.
- NEAR MISS - it trips randomly with no pattern — More often a shared, overloaded circuit than a faulty machine.
Causes, ranked for a built-in machine of this design
- Water reaching the door-mounted controls — First on this platform: the controls and the latch switch live inside the door, so an inward leak lands straight on them.
- A loose or corroded connection in the supply box — Second. The box sits behind the kick plate at floor level, gets damp, and a loosening connection arcs quietly.
- Heating element shorting to the tub — Third, and the classic same-stage trip, because the element is energised only during heat and dry.
- Harness chafe at the door hinge — Fourth. The loom flexes on every open and close until the insulation wears through.
- An overloaded or shared branch circuit — Last as a fault, first as an explanation for random trips - a machine sharing with a disposer trips on load alone.
The order, and why it stops early
- Record the cycle stage, then kill the breaker — The stage is your only diagnostic evidence and it is free to capture.
- Look for water tracks under the door and at the kick plate — Visible from outside, and it separates the top two causes with no tool.
- Ask what else shares the circuit — A question rather than a test, and it explains random trips entirely.
- Everything after that is a technician's job — The rest sits behind live terminals, with no safe owner test.
What an owner should do, and where it ends
- Switch off the dishwasher's breaker — Do this before any inspection, and leave it off.
About 5 min
- Write down the stage at which it trips or smells — Fill, wash, heat or dry - and whether it is the same stage every time.
About 5 min
- Look along the floor at the kick plate — Staining, a swollen cabinet base or a damp patch tells the technician where to start.
Tools: torchAbout 10 min
- Check what else is on that circuit — With the breaker off, see what else in the kitchen lost power.
About 10 min
- STOP - do not remove the kick plate or the door panel — Both expose mains terminations, which may be live even when the machine looks idle.

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 defeat the door latch or its switch to run the machine open: the latch cuts power to the heat and wash circuits and is why the door is safe to touch. Never reset a breaker repeatedly to finish a load. A US household branch circuit is 15 A or 20 A at 120 V, and a dishwasher belongs on one not shared with other heavy loads. If you smell gas: do not switch anything on or off, leave the building, and call the gas utility or 911 from outside. Do not look for the leak yourself.
When to call, which is nearly always here
Call for every symptom on this page. This is the one fault class where owner diagnosis has almost no safe range: a breaker tripping on an appliance, a burning smell, visible charring or a tingle from the casing all call for a qualified visit rather than another test. Call an electrician instead if the breaker trips with the dishwasher isolated - then the house circuit is at fault and the machine is a bystander.

The limits of a generalized page
This is generalized information for dishwashers carrying this nameplate as a class, and it deliberately contains no measurements. Where a family- or model-specific page exists it is the more specific answer and is linked here. Absent on purpose: element resistance values, terminal layouts, harness routing and your machine's rating-plate figures. Those need a service manual and a meter.
