First, check the power cord. Look for damage or breaks. Replug if the connection is loose, and replace with a same-spec copper wire if damaged.

Next, open the back cover to check internal terminals. Tighten loose wires with a screwdriver.

Finally, check the motor and circuit breaker. Replace the carbon brush if it’s worn below 5mm (if the motor doesn’t run). Reset the circuit breaker and reduce the number of clothes per load to avoid overloading.
