The short answer
Treat any burning smell, scorched connector, repeated breaker trip or tingle from a Contoure washer as urgent and stop using the machine now. In a coach the supply itself is a live suspect: pedestal wiring, generator output and inverter output are all far more variable than a household circuit, and a bad ground shows up here first. This is not an owner repair beyond isolating the machine.
What you are actually seeing
- A hot plastic or burning smell during or shortly after a cycle — Means: on-page
- The breaker or the GFCI trips whenever the machine reaches a particular part of the cycle — Means: on-page
- A tingle when touching the drum, the door or the cabinet while the machine runs — Means: on-page
- Browning, melting or soot around the plug, the outlet or the terminal block — Means: on-page
- Lights in the coach dim noticeably whenever the machine draws — Means: on-page
- The machine is simply dead with no smell and no trip — Means: different-fault — Go to: contoure-washer-wont-start
- A musty smell rather than a burning one — Means: different-fault — Go to: contoure-washer-smell-mold
- Body: A hot plastic or burning smell during or shortly after a cycle. The breaker or the GFCI trips whenever the machine reaches a particular part of the cycle. A tingle when touching the drum, the door or the cabinet while the machine runs. Browning, melting or soot around the plug, the outlet or the terminal block. Lights in the coach dim noticeably whenever the machine draws. Some near-miss symptoms belong on a different page: The machine is simply dead with no smell and no trip points at a supply or interlock problem rather than a hazard, covered on contoure-washer-wont-start; A musty smell rather than a burning one points at biofilm or tank odour, covered on contoure-washer-smell-mold.
Causes, ranked for this machine
- A poor or corroded connection at the plug, the outlet or the coach terminal block — Why this rank: This is first because vibration in a moving vehicle loosens connections that would stay tight for a decade in a house, and a loose joint is what heats up and chars
- A pedestal, generator or inverter supply with a bad ground or reversed polarity — Why this rank: A tingle on the cabinet is a grounding symptom, and coach supplies fail this far more often than house circuits
- Water reaching a component or a connector, tripping the GFCI at a repeatable point in the cycle — Why this rank: A trip that always happens at the same cycle step is water finding the same place each time
- An undersized or damaged extension lead between the pedestal and the coach — Why this rank: Owners commonly power a coach through a lead that is fine for lighting and marginal for a motor load
- A failed motor, heater or capacitor drawing a fault current to earth — Why this rank: Last in likelihood but the most serious, and the only one that is certainly a service call
- Body: Most likely: A poor or corroded connection at the plug, the outlet or the coach terminal block. This is first because vibration in a moving vehicle loosens connections that would stay tight for a decade in a house, and a loose joint is what heats up and chars. Next most likely: A pedestal, generator or inverter supply with a bad ground or reversed polarity. A tingle on the cabinet is a grounding symptom, and coach supplies fail this far more often than house circuits. Third: Water reaching a component or a connector, tripping the GFCI at a repeatable point in the cycle. A trip that always happens at the same cycle step is water finding the same place each time. Fourth: An undersized or damaged extension lead between the pedestal and the coach. Owners commonly power a coach through a lead that is fine for lighting and marginal for a motor load. Fifth: A failed motor, heater or capacitor drawing a fault current to earth. Last in likelihood but the most serious, and the only one that is certainly a service call.
What to check, in order
- Switch the machine off at its breaker and unplug it before anything else
- Inspect the plug, the outlet and any extension lead for heat damage, browning or a smell
- Test the supply with a polarity and ground tester at the outlet the machine uses
- Note whether the trip always happens at the same point in the cycle, and write down which point
- Body: First, switch the machine off at its breaker and unplug it before anything else. Second, inspect the plug, the outlet and any extension lead for heat damage, browning or a smell. Third, test the supply with a polarity and ground tester at the outlet the machine uses. Fourth, note whether the trip always happens at the same point in the cycle, and write down which point.
Checks you can safely make yourself
- Switch off the breaker for the machine and unplug it, then leave it isolated until the cause is identified — Tools: none — Time estimate: a few minutes
- Look closely at the plug pins, the outlet face and any extension lead connector for browning, melting or a burnt smell — Tools: torch — Time estimate: a few minutes
- Plug a polarity and ground tester into the outlet the machine uses and read it on shore power and again on generator power — Tools: outlet tester — Time estimate: a few minutes
- Run the machine only if it is safe to do so, and note the exact cycle step at which the breaker or GFCI trips — Tools: notepad — Time estimate: one cycle at most
- Check that the machine is not sharing an overloaded circuit by switching off other loads on the same breaker — Tools: none — Time estimate: a few minutes
- Body: Step one: Switch off the breaker for the machine and unplug it, then leave it isolated until the cause is identified. Tools: none. Time: a few minutes. Step two: Look closely at the plug pins, the outlet face and any extension lead connector for browning, melting or a burnt smell. Tools: torch. Time: a few minutes. Step three: Plug a polarity and ground tester into the outlet the machine uses and read it on shore power and again on generator power. Tools: outlet tester. Time: a few minutes. Step four: Run the machine only if it is safe to do so, and note the exact cycle step at which the breaker or GFCI trips. Tools: notepad. Time: one cycle at most. Step five: Check that the machine is not sharing an overloaded circuit by switching off other loads on the same breaker. Tools: none. Time: a few minutes.
Safety first
Safety
Do not reset a breaker repeatedly, do not remove a panel, do not bypass a GFCI and do not use the machine while you investigate. Do not open the cabinet: capacitors in the drive circuit can hold a charge after the power is off. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. unplug-before-service
Where the owner fix ends
This is the one symptom where the answer is call now rather than try one more thing. Any scorching, any tingle, any repeated trip and any burning smell should go to a technician with the machine isolated. Owner work stops at unplugging the machine, looking at the plug and the outlet, and testing the supply.
