No—Wi-Fi is not needed for a washing machine to wash clothes. It connects a compatible washer to an app for optional features such as cycle alerts, progress checks, scheduling, remote control, downloadable cycles, or troubleshooting. Whether those extras are useful depends on the exact model and whether you will use them.

What Wi-Fi adds to a washing machine

A connected washer uses a manufacturer’s app to communicate over Wi-Fi. Depending on the model, app, and country, that may let you:

  • Check cycle progress or remaining time.
  • Receive a notification when a cycle finishes or an error occurs.
  • Schedule a wash or start it remotely, when the model supports those functions.
  • Download additional wash programs or access troubleshooting tools.
  • View energy-use information on some supported models.

These are examples across different brands, not a standard feature list for every Wi-Fi washer. Check the documentation for the exact regional model you are considering. LG ThinQ laundry app features, Samsung SmartThings washer support, and the Whirlpool App describe different capabilities and requirements.

What the major apps can do

Brand and app Documented examples Important qualification
LG ThinQ Remote start, cycle monitoring, notifications, downloadable programs, Smart Diagnosis, and energy monitoring on supported models. Features depend on model and country. LG’s US instructions require enabling Remote Start at the washer; if its door has been opened, a cycle cannot be started remotely. LG USA support instructions (12 December 2021).
Samsung SmartThings Notifications and remote washer management; Samsung also documents a delayed-start procedure for supported washers. The delayed-start steps and available functions should not be assumed to apply to every model. Samsung US support.
Whirlpool App Schedule a wash, track progress, and receive completion notifications. The washer must be remote-enabled, and the app and Wi-Fi are required. Whirlpool notes that features may change. Whirlpool App details.

Remote start still has limits

“Remote control” does not necessarily mean you can load laundry from anywhere and start a wash without preparation. You may need to put in clothes and detergent, choose settings, power on the washer, and enable remote use at the appliance first.

LG WM4200HBA / WM4200HBA / WM4200HBA 5.0 Cu. Ft. Mega Capacity Smart wi-fi Enabled Front Load Washer with TurboWash 360 and Built-in Intelligence
  • High-Efficiency Front-Load Washer – ENERGY STAR certified design delivers powerful cleaning performance while helping reduce annual energy consumption to approximately 105 kWh/year.
  • Large 5.0 Cu. Ft. Capacity – Easily handles bulky items like comforters and large laundry loads, reducing the number of cycles needed.
  • Depth With Door Open (Maximum 55 inches) – Requires up to 55 in. of clearance with the door fully open (90°) for convenient loading and unloading.
  • Smart ThinQ Technology – Wi-Fi enabled washer allows remote monitoring, cycle control, and notifications through the LG ThinQ app.
  • Quiet & Durable Inverter Direct Drive Motor – Designed for reduced vibration, quieter operation, and long-term reliability.

For example, LG’s US instructions for the covered top-load washer say to hold Remote Start for three seconds before starting through the app; opening the door blocks remote start. Whirlpool also requires the appliance to be set to remote enable. These steps are model-specific, so consult the washer’s manual rather than relying on a brand-wide assumption.

Does Wi-Fi make a washer more energy-efficient?

Not by itself, based on the available manufacturer information. Some supported LG models report energy use, but a report is information about use—not evidence that connectivity reduces consumption or bills. Compare the washer’s stated efficiency and your likely usage separately from its app features.

What to consider before buying

Connectivity is only one part of choosing a washer. Compare the full appliance on the factors that affect your household:

  • Price, dimensions, and capacity: Confirm the washer fits the space and handles the loads you typically wash.
  • Wash performance and efficiency: Give these priority over app features if they matter more to your purchase.
  • Specific app functions: Decide whether alerts, progress checks, scheduling, or another documented feature would solve a recurring problem.
  • Remote-start setup: Check what you must do at the machine before the app can start a cycle.
  • App and network requirements: Confirm that the model is compatible, the service is available in your country, and any required registration is acceptable. LG’s UK guidance, for example, specifies compatible appliances and registration.
  • Exact model documentation: A “smart” label or brand name does not establish which features a particular regional model supports.

When a Wi-Fi washer is worth it

A connected model may be worthwhile if a supported function would regularly help—for instance, an alert when you are away from the laundry room or a progress check when you cannot see the machine. If you normally load and check the washer in person, and its app features would not change your routine, Wi-Fi may add little value. That is a practical way to weigh the documented conveniences, not a guarantee that a connected model is better overall.
