LG washing machine trips the circuit breaker when turned on

It can be annoying and concerning if your LG washing machine trips the circuit breaker each time you turn it on. This issue throws off your laundry schedule and might be a sign of a bigger electrical problem that needs to be fixed.

This could be occurring for a number of reasons, ranging from straightforward ones like a broken power cord to more complicated ones like malfunctioning internal components. Knowing these reasons will enable you to diagnose the issue and determine whether you can resolve it on your own or if you need to hire an expert.

This post will examine the typical causes of this problem and walk you through the troubleshooting and resolution procedures. With helpful hints and guidance, we can help you resolve any issue, no matter how big or small.

Power grid or washing machine?

It is extremely risky for the wiring to react in this way when the washing machine is turned on. First of all, the machine is vulnerable because its control board dislikes abrupt voltage drops. Second, there is a risk of a short circuit and fire because network surges can also harm the insulation around the wires. Thirdly, the malfunction itself poses a risk of unpleasant outcomes; if the breakdown is not resolved, there is a good chance that it will recur or worsen.

It is crucial to determine right away whether the wiring or the machine is at fault. It will be necessary for you to regularly inspect the primary trouble spots if the LG washing machine trips the fuses. With an active warranty, it is preferable to get in touch with the service center’s experts for diagnostics because there are multiple potential "pain points."

Failure of the wiring presents a different issue. In this situation, you should either independently check all of the power circuits outside the washing machine or call an electrician. The most common cause of tripped fuses is weak connections. We advise you to start diagnostics right away without delay.

Let"s check the wiring

Pay close attention to the wiring first. When multiple problems occur at once, the machine may automatically shut off or the fuses may blow.

Electricity self-shutdown is an essential safety feature meant to guard against short circuits and current leaks in buildings.

• Poor-quality, unsuitable or unregulated RCD. The most common problem leading to a power outage in the room even with a slight network load. The situation can be solved by purchasing a device with a higher capacity, from a trusted manufacturer, or by adjusting the faulty part.
• Disproportionate load on the meter. The wiring is designed for a certain power, and when the permissible value is exceeded, an emergency shutdown occurs. For example, not everyone can afford to plug in a refrigerator, washing machine, microwave oven, and electric stove at the same time. There are two solutions: replace the entire electrical network with a more reliable one or operate the devices one by one.
• Damaged network. It is possible that a wire break, insulation or socket integrity has been compromised in a certain section of the circuit. It is easy to check the assumption – turn on a device with a similar power and watch the machine"s reaction. If the situation repeats itself, then call an electrician.

Usually, only experts can handle electrical issues in apartments. Working with wires, machines, and meters requires a high level of training and experience. If not, there is a significant chance of mishap, overheating, and fire.

Possible problems with the machine

The washing machine is the cause if there are no issues with the apartment’s power supply. You will need to disassemble the device, examine it, and run the required diagnostics in order to resolve the issue. However, you should unplug the washing machine from the network and use the emergency drain to empty out any remaining water in the machine before you crawl under its body. A high risk of mechanical or electrical injury exists otherwise. Following our attention to your safety, we examine the list of potential issues that could cause the machine to shut off:

• damaged power cord or plug;
• caused short circuit of the heating element;
• faulty network filter;
• broken engine;
• failed interference filter;
• non-working control buttons on the dashboard;
• frayed internal wiring or loose contacts.

Starting with the most common and straightforward breakdown, the check should progress to the most costly and infrequent breakdown. Ideally, it is best to get in touch with experts right away for a thorough machine diagnostic. However, if you follow the guidelines below, you can complete it on your own.

Plug or power cord?

Examining the plug and power cord is the first step in the repair process. The power cord is typically stretched, pinched, or twisted during illiterate operation, which alters the current flow to the device. Stated differently, poor contact between the plug and socket prevents the machine from operating at its maximum potential. It’s easy to check the cord by using a multimeter to punch it. Should any damage be found, a replacement will be necessary.

1. Make sure that the machine is disconnected from the power supply.
2. Close the inlet valve.
3. Drain the water using the emergency drain.

When attempting to empty the water from the washing machine, it is strictly prohibited to turn it over!

1. Unscrew the bolts holding the back panel.
2. We find the network filter and take it out of the machine: press the latches, remove the plastic stopper and squeeze it out of the case.
3. Gently take out the wire from the washing machine.

The only thing left to do is buy a new cord, using the old one as an example in the store. Following the installation of the wire, follow the directions in reverse order. At the conclusion, we initiate a test washing to ensure that the work was completed correctly.

Every time you turn on your LG washing machine, if the machine trips the circuit breaker, there may be an issue with the electrical setup or the machine itself. This might be the result of a broken power cord, a circuit that is overloaded, or even an internal problem with one of the washer’s parts. Finding and resolving the issue is essential to avoiding additional harm and guaranteeing the safe and effective operation of your appliance.

Heating element

It may also cause the machine to self-destruct. Water that is too hard or poor quality causes a lot of scrape, which builds up contaminants and chemicals in the heater and eventually causes the element to overheat and close internally. Reacting to the leak, the wiring disables the counter and causes traffic bottlenecks.

Disconnect the cord and use a multimeter to measure the resistance to inspect the heater. Set the device’s 200 Ohm limit, attach the probes to the contacts, and assess the outcome on the scoreboard. In general, the indicator shouldn’t be more than 20–50 Ohms.

Not only that, but an external "short circuit" must be ruled out. We use a multimeter to measure each of the ground bolts and the heating element’s outputs individually. As even low values indicate a problem, the indicator will typically be zero. It is necessary to replace the heating element if there are evident issues. If you follow the following algorithm, you can do this by hand:

1. remove the back panel;
2. find the heater;
3. unscrew the retaining bolt;
4. pry the heating element with a screwdriver and remove it.

You have to exercise extreme caution. It is simple to damage the contacts or squeeze the element out of the tank by overtightening the nut.

Motor or network filter?

Since the network filter is in charge of maintaining the electrical voltage, it makes sense that it would respond to variations by turning off the RCD. The component has to be changed if this occurs. Melted contacts and unfavorable readings on the multimeter display will be obvious indicators.

Both components need to be changed when the filter has an integrated electrical wire.

Lead to a shutdown caused by a damaged tank or hoses, as well as a short circuit in the motor’s wiring from prolonged use. We use a tester to ring the engine in order to check, and if a deviation is noted, we fix or replace it. Electric brushes can become worn out, but replacing them is simpler in this case because the old ones are removed.

When you turn on your LG washing machine, if something isn’t functioning properly, it trips the circuit breaker. Numerous things, such as a malfunctioning power cord or an internal short circuit, could be the source of this problem. It’s critical to take immediate action to fix this issue in order to protect your safety and stop additional damage to your appliance.

A broken power cord or an issue with the outlet are common examples of basic problems that could be the source of the issue. More significant problems, such as a broken motor or an issue with the internal wiring, might call for expert assistance. It can be risky to attempt solving complicated electrical problems on your own, so if you’re unsure, don’t be afraid to call in a licensed technician.

Future incidents of this nature can be avoided with careful use and routine maintenance. Don’t ignore any warning indications that come to you, such as strange noises or burning smells. Maintaining your washing machine will not only increase its lifespan but also reduce the risk of electrical hazards in your house.
