The short version
A Danby dishwasher that trips a protective device or smells of burning is telling you something is failing to earth or overheating. Neither is an owner repair, and continuing to use the machine is the only genuinely wrong response. What sits behind that ordering: this is a specialist in compact and secondary-space appliances rather than full-size kitchen equipment.
What the owner observes
- The protective device trips when the machine is switched on — A fault to earth somewhere in the appliance or its supply.
- A smell of hot plastic or burning during a cycle — A connection overheating; stop using the machine immediately.
- A tingle or a shock from the door or the worktop — Stop, isolate at the breaker and call an electrician; do not touch it again.
- NEAR MISS — it stops mid-cycle without tripping anything — That is a cycle fault, and drainage is the usual cause.
Ranked causes for this brand and appliance
- Heating element failed to earth — The signature is a trip that happens at the same point in every cycle, which is when the heater energises. Ranked first here because a compact appliance has a short airway, a small cavity and one of everything, so a single blockage or a single failed switch stops the whole machine.
- Supply connection loose or overheating — This is a fire risk in its own right and it is a job for an electrician rather than an appliance technician. Second, because these units are moved between rooms and tenancies far more often than a fitted appliance, and everything that follows from being moved sits high in the ranking.
- Water reaching an electrical component — A slow leak inside the cabinet wets a connector or the control, and the fault appears intermittently and then permanently.
- Damaged mains lead — It usually trips on movement rather than at a particular point in the cycle.
- Pump or motor winding failing — It is less common than a heater fault and produces the same repeatable trip point at a different phase.
What to check first, second, third
- Note whether the trip happens at the same point in the cycle every time — First — A repeatable trip point identifies the component that energises at that moment.
- Look at the plug, the socket and the spur for discolouration or a smell of hot plastic — Second — Visible scorching means the fault is on the supply side and needs an electrician now.
- Look for signs of water inside the cabinet base or at the door skin — Third — It links two symptoms into one cause and changes the urgency.
Steps you can take yourself
- Look at the plug, socket and spur for scorching — Discolouration or a smell of hot plastic means an electrician rather than an appliance technician.
Tools: torchAbout 10 min
- Note exactly when the trip occurs — On switch-on, at fill, at wash, at drain — the timing names the component.
About 5 min
- STOP — do not reset repeatedly and do not open the machine — A device that trips again is reporting a real fault; resetting it repeatedly is unsafe.
Safety first
Safety
Isolate the dishwasher at the breaker before touching anything, and leave it isolated until a technician has seen it. A capacitor can hold a charge after the power is off. allowlist:unplug-before-service allowlist:branch-circuit-15-20a
Where the owner fix ends
Call immediately, and stop using the machine in the meantime. Every cause on this page is either a fire risk or a shock risk, and none of them is an owner repair. Mention the installation when you call — these appliances live in garages, basements, offices and small apartments, often on an extension lead or a shared circuit.

What this page does not cover
This page covers the Danby dishwasher as a class rather than one family or model line. Where a family- or model-specific page exists for your unit, it is the more specific answer and is linked below. Not covered here: element ratings, circuit specifications and the internal wiring layout, which differ by model line and are an electrician or technician matter.
