To check if the drain pump is the cause of the issue, unplug the appliance from the mains, unplug the drain pump and plug the appliance back into the mains. If the main circuit breaker doesn't trip any more after the drain pump has been unplugged, it means you will need to replace the latter.
The drain pump drains the water out of your washing machine. The circuit breaker will trip:
If the appliance is leaking water, it is very likely that the circuit breaker will trip at some point. When this happens, you should dismantle your machine and try to see where the traces of water or limescale are coming from. If you can't find the part at fault, unplug each element one by one and run a few tests. Always try to find the leak before changing any part.
Your appliance trips the electric once the door is closed and the safety latch (or door lock) is stuck and cannot be closed or opened after this power cut. Your washing machine could then be tripping off the power for several reasons: more
GFCIs should be checked monthly by operating the push-buttons on the front labeled "Test" and "Reset." In addition to checking for proper operation, monthly testing also makes sure the mechanical components of the receptacle are in working order. Simple GFCI testers are available for less than $15, or for less than $150, you can purchase a high-quality, industrial electrical tester can check for energized circuits, test AC and DC voltages, resistance, continuity, and phase rotation between any two phases and GFCIs.
GFCIs are designed to prevent bodily harm from electrical faults that could cause electricity to flow through you to ground. When a GFCI breaker trips, it It quickly disconnects the current flowing through an unintended ground path even if the amount of current is too small to trip a typical circuit breaker. Although fuses and circuit breakers are also protective devices, they are designed to protect equipment and facilities from short circuits and large magnitude electrical faults that could cause electrical fires and property damage. The actuating energy for standard breakers and fuses far exceeds the lethal amount, but most GFCIs trip at around 6 mA.
A GFCI uses a current transformer to detect the difference between the line current supplied to the load and the neutral current returning from the load. Ideally, this difference should be zero because both currents cancel. If there is a current differential, it becomes the input to a comparator within the GFCI, which changes states when the differential is around 6 mA. When the comparator changes states, it triggers a silicon-controlled rectifier, which disconnects the power from the output of the GFCI.
Another name for a ground fault is leakage current. Although wiring insulation is designed to keep electricity in the conductor, all insulators have some conductivity. While not perfect, even air can be an insulator. Insulation conducts current through both electrically resistive and capacitive paths. If insulation is old or damaged its resistance is lower and leakage current could become substantial. The insulation protecting longer conductors has higher capacitance, which can cause even more leakage current. more

Measure the leakage current on each leg of the circuit to identify which one has considerably more leakage than the others. If one leg has a suspiciously high leakage current, ensure that the equipment is operating properly. Remember that surge suppression filters and capacitors on the power input of some electronic equipment can increase the overall circuit capacitance, which can increase leakage current. Determine loaded circuit leg leakage with the equipment "on"—switching the equipment "off" allows you to determine just the circuit wiring leakage.

On GFCI-protected circuits, leakage current can cause unnecessary and intermittent tripping. When troubleshooting these intermittent "ghost" trips, sometimes looking for the leakage current culprit can be costly. When many pieces of equipment are operating on a circuit, the leakage current is cumulative and could be in the order of milliamps. Adding more equipment to a GFCI-protected circuit could cause a GFCI to trip randomly, making the problem difficult to diagnose.
A ground fault circuit interrupter (GFCI) is one of the most common residential, commercial, and industrial safety devices. The most common types are single-phase electrical outlets used in households near water sources, such as in kitchens, bathrooms, and outdoor receptacles. Most states have required GFCI outlets in certain areas of residential installations for decades. However, NFPA 79, the Electrical Standard for Industrial Machinery, also dictates their use in industrial applications.
