Why Does My Samsung Washing Machine Keep Tripping the Electrics?
Unplug the machine, remove any standing water from the drum, and check the plug and power cable for visible damage or scorch marks before resetting the breaker — if the breaker holds with the machine unplugged, the fault is confirmed as appliance-side (takes about 10 minutes).
Fault description
When a Samsung washing machine trips the electrics, it usually means the appliance is drawing a fault current large enough to trigger your home's RCD (residual current device) or circuit breaker. This is a protective response — the electrics are doing exactly what they should — but it does mean something inside the machine is causing an unintended path to earth or an overload condition.
The trip can happen the moment you switch the machine on, as soon as water enters the drum, partway through a cycle, or during the spin phase. Each of these timing clues points toward a different component, so noting exactly when the trip occurs will help you narrow down the cause before you start investigating.
Because this fault involves mains electricity, it is rated as advanced severity. Some checks are safe for a homeowner to carry out, but others require the machine to be isolated and, in several cases, a service technician should be involved.
Causes
- Faulty heating element — The heating element is the most common cause of tripping in washing machines. Over time the element's insulation breaks down, allowing current to leak to the metal drum or cabinet and triggering the RCD. Trips that occur shortly after the cycle starts — when the heater first switches on — strongly suggest this component.
- Damaged or waterlogged motor — The main drive motor can develop an earth fault if its windings become moisture-damaged or if the carbon brushes wear down and create arcing. A trip that happens consistently during the spin phase or when the drum first starts to turn often points to the motor.
- Faulty or leaking water inlet valve or pump — If water is leaking internally onto electrical components — such as the motor, control board, or wiring loom — it can create a conductive path to earth. A trip that only occurs once water enters the machine is a key indicator of this type of fault.
- Damaged power cable, plug, or internal wiring — A chafed or pinched power cable, a loose connection inside the plug, or damaged internal wiring can all cause intermittent or immediate tripping. Visible scorch marks, a burning smell, or a discoloured plug face are warning signs to look for before doing anything else.
- Failed control board or capacitor — A short circuit on the main PCB or a failed motor start capacitor can draw excessive current and trip the breaker. This type of fault is less common but tends to cause an immediate trip the moment the machine is powered on, even before a cycle begins.
- Worn door seal allowing water onto wiring — A cracked or perished door gasket can allow water to drip down onto the wiring harness or motor below the drum. The fault may appear intermittent at first, worsening over time as the seal deteriorates further.
Step-by-Step Fix
- 1
Isolate the machine and inspect the plug and cable
Switch off and unplug the washing machine before doing anything else. Examine the plug for scorch marks, melted plastic, or a burning smell. Run your hand along the full length of the power cable feeling for kinks, cuts, or areas where the outer sheath has worn through. If you find any damage here, do not use the machine — replace the cable or plug before proceeding.
- 2
Test whether the machine alone is causing the trip
Reset your circuit breaker or RCD, then plug the washing machine into a different socket on a different circuit if possible, or try a different appliance on the same socket to confirm the socket itself is not faulty. If the breaker trips only when the Samsung machine is connected, the fault is confirmed as being within the appliance.
- 3
Check for visible water leaks inside the machine
Remove the lower access panel (usually held by two screws at the base front). Use a torch to look for signs of water pooling around the motor, pump, or wiring. Even a small drip onto a connector can cause an earth fault. Dry any moisture you find with a cloth and allow the machine to air out for several hours before testing again.

Inspect and clean the door seal
Pull back the rubber door gasket and look for cracks, tears, or mould build-up that could be causing water to escape the drum area. A damaged seal should be replaced — it is a relatively affordable part and straightforward to fit on most Samsung models. Replacement seals are available by searching your model number.
- 5
Test the heating element for an earth fault
With the machine unplugged, access the element from the rear panel. Disconnect the element's wiring connectors and use a multimeter set to resistance (Ω) to test between each element terminal and the machine's metal chassis. A reading of anything other than open circuit (OL or infinite resistance) indicates the element insulation has failed and the element needs replacing.
- 6
Check the motor brushes and motor condition
On brush-motor models, remove the motor (typically accessed from underneath after removing the lower panel) and inspect the carbon brushes. Brushes worn down to less than 5 mm should be replaced as a pair. While the motor is out, check the winding terminals against the chassis with a multimeter in the same way as the element test above.
- 7
Inspect the control board for burn marks or failed components
If all other components test normal, carefully remove the top panel and locate the main PCB. Look for any visibly burnt or discoloured components, swollen capacitors, or areas where the board has scorched. A damaged control board will need professional assessment or replacement — do not attempt to repair individual board components unless you have electronics experience.
When to call a service technician
You should contact a service technician if the circuit breaker trips immediately every time the machine is plugged in, if you can smell burning from inside the machine, or if you have tested the element and motor and both appear sound but the fault persists. These scenarios suggest a wiring loom fault or a control board failure that requires specialist diagnostic equipment to locate safely.
You should also call a technician if you are not comfortable working around mains-voltage components, or if the machine is still under warranty — attempting internal repairs yourself may void the cover. A qualified service technician can carry out a full earth leakage test and identify the faulty component without risk.
Prevention
The parts most commonly replaced when a Samsung washing machine trips the electrics are the heating element, the motor carbon brushes, and the door seal. Keeping the door seal clean and free from mould reduces the risk of water tracking onto electrical components, and running a monthly drum-clean cycle helps prevent detergent residue build-up that can accelerate seal deterioration. Avoid overloading the machine, as this puts extra strain on the motor and can shorten its working life.
If you need to replace any of these components, use the search tool below to find parts compatible with your specific Samsung model number — always match parts to your exact model to ensure a safe and correct fit.

Frequently Asked Questions
Is it safe to keep resetting the breaker and using the machine?
No. A tripping RCD or breaker is a warning that a fault current is present. Repeatedly resetting and running the machine risks electric shock, damage to your home's wiring, or a fire. The machine should remain unplugged until the fault has been identified and repaired.
Why does my Samsung washing machine only trip the electrics when it heats the water?
If the trip happens a few minutes into the cycle — typically when the water reaches washing temperature — the heating element is almost certainly the cause. The element's internal insulation has broken down, and current leaks to the chassis as soon as the element energises. Replacing the element usually resolves this immediately.
Could a faulty extension lead or socket be causing the trips?
Yes, though it is less common. A damaged extension lead, an overloaded multi-socket adaptor, or a faulty wall socket can all cause nuisance tripping. Always plug a washing machine directly into a dedicated wall socket rated for the appliance's current draw, and never use an extension lead as a permanent solution.
My machine trips the electrics but only sometimes — what does that mean?
Intermittent tripping often points to a component that is on the borderline of failure, or to a water leak that only reaches electrical parts under certain conditions — for example, during a full drum load when water levels are higher. It can also indicate a loose wiring connection that makes and breaks contact during vibration. Intermittent faults can be harder to diagnose but should still be investigated promptly, as they tend to worsen over time.
How much does it typically cost to repair a washing machine that trips the electrics?
If the fault is a heating element or motor brushes, these are relatively low-cost parts and the repair is often economical. A control board replacement is more expensive and may not be cost-effective on an older machine. A service technician can give you a diagnosis and quote before any work is carried out, allowing you to make an informed decision about repair versus replacement.
