There is a six year old LG washing machine that is in good condition. The average lifespan of a clothes washer is about 14 years, assuming seven loads per week. You can extend the lifespan of your washer by doing fewer loads per week and also not frequently overloading the machine beyond its capacity to reduce stress on its mechanical parts.
The washer supply lines are plastic hoses. We always recommend braided steel lines as they are more resilient to kinks, knicks and other accidental damage. Regardless of which type of hose is used, we recommend replacing them every 5-7 years.
Every time a washing machine shuts off the water a shockwave is sent through the hoses that puts repeated stress on them. As hoses age and lose their flexibility, they are more likely to burst from this pressure. Burst washing machine hoses are one of the leading causes of catastrophic water damage in homes.
