Smart appliances get better with software updates, but only if those updates are installed correctly.
This guide explains how to update smart appliance software, why it matters, and what to check before and after each update.
Why smart appliance software updates matter
Smart appliances such as refrigerators, ovens, dishwashers, washing machines, thermostats, and robot vacuums rely on firmware, mobile apps, and cloud services to function.
Manufacturers use updates to fix security vulnerabilities, improve Wi-Fi and Bluetooth connectivity, add new features, and resolve bugs that affect performance.
Without updates, devices may become unstable, stop syncing with your home network, or remain exposed to known threats.
In many connected homes, the appliance itself is only one part of the system; the companion app, router, and cloud platform all need to stay current.
What types of updates do smart appliances use?
Different brands use different update paths, but most smart appliances rely on one or more of the following:
- Firmware updates: Low-level software that controls the appliance’s internal functions.
- App updates: Improvements to the mobile app used for remote control, alerts, and scheduling.
- Cloud or service updates: Changes handled by the manufacturer’s backend systems.
- Network or module updates: Updates for Wi-Fi, Bluetooth, or Zigbee components inside the appliance.
Understanding the type of update helps you know where to look and what to expect.
A thermostat may update automatically through its app, while a refrigerator may require confirmation on the appliance display.
How to update smart appliance software
The exact steps vary by brand, but the process is usually similar.
Start by checking the manufacturer’s app or the appliance’s control panel for a software, firmware, or device update option.
Many brands also send push notifications when an update is available.
- Open the manufacturer’s app and sign in to the account linked to the appliance.
- Select the device you want to update from the home dashboard.
- Look for settings, device info, or firmware and check for available updates.
- Confirm the update if the app asks for permission or an estimated time window.
- Keep the appliance powered on and connected to a stable Wi-Fi network until the update finishes.
- Restart the device if the app or display instructs you to do so.
If the appliance supports automatic updates, verify that the feature is turned on.
For devices that do not update automatically, set a reminder to check monthly or after major app releases.
Where to find update settings on common smart appliances
Update menus are often hidden inside device settings, account settings, or support sections.
The wording may differ, but the location is usually easy to find once you know what to look for.
In the mobile app
Most smart home apps place update controls under Device Settings, About, Product Information, or Advanced Settings.
Look for labels such as firmware version, software version, or update available.
On the appliance display
Some ovens, refrigerators, and washers include a touchscreen or control panel with a settings menu.
There may be an option such as Software Update, System Update, or Check for Updates.
In the web portal
Certain brands, especially those tied to smart home ecosystems, provide update controls through a web dashboard.
This is common for appliances managed through a larger platform account rather than a single app.
Before you update, check these basics
A failed update can cause temporary outages, missing settings, or the need to reset and reconnect the appliance.
A few minutes of preparation can prevent most problems.
- Confirm Wi-Fi stability: Weak signal strength can interrupt downloads and installations.
- Check power status: Keep the appliance plugged in and avoid unplugging it mid-update.
- Review compatibility: Make sure your phone app, operating system, and appliance model support the new version.
- Back up settings if possible: Save schedules, temperature preferences, automations, and custom modes.
- Read release notes: Manufacturers often explain what the update changes and whether a restart is required.
If the appliance controls critical functions, like refrigeration or climate management, update during a time when you can monitor it.
That makes it easier to respond if the device pauses or restarts.
How to update smart appliance software automatically
Automatic updates are the easiest option when the manufacturer supports them.
They typically download in the background and install during low-use periods, such as overnight.
To use automatic updates, open the app and look for a toggle such as Auto Update, Install Updates Automatically, or Allow Background Updates.
Even when automatic updates are enabled, some devices still require approval before installation.
This is common for appliances that need a restart or a brief service interruption.
Keep notifications enabled so you do not miss the prompt.
How to update a smart appliance manually
Manual updates give you more control and are often preferred for major firmware releases.
They are useful when you want to read notes first, schedule downtime, or confirm that the update applies to your exact model.
Use the app or control panel to start a manual check.
If an update is found, follow the on-screen instructions carefully.
Do not close the app, force quit the process, or switch networks while the device is downloading or installing files.
After installation, the appliance may reboot, reconnect to Wi-Fi, or show a progress indicator.
Wait until the process is complete before testing normal functions.
Common problems during smart appliance updates
Most update issues come from connectivity, power interruptions, or account sync errors.
Knowing the common failure points makes troubleshooting faster.
- Update stuck at a percentage: The device may need more time, a stronger signal, or a restart.
- App says no update is available: The rollout may be gradual, or your model may already be current.
- Device disconnects from Wi-Fi: Reconnect the appliance to the network and try again.
- Update fails repeatedly: Check for low storage, app permission issues, or a temporary server problem.
- Settings reset after update: Re-enter preferences, schedules, and automations if needed.
If the appliance becomes unresponsive, consult the manufacturer’s support documentation before trying a factory reset.
A reset can erase local settings and require a full reconfiguration.
Security and privacy tips for connected appliances
Updating software is only one part of securing a smart appliance.
Strong account habits and network hygiene also matter.
- Use a unique password for the appliance account.
- Enable two-factor authentication if the brand supports it.
- Keep the companion app updated on iPhone or Android.
- Use a secured home Wi-Fi network with WPA2 or WPA3.
- Remove old devices from your account if you replace or sell an appliance.
Because smart appliances often collect usage data, update prompts can also include privacy policy changes or permission adjustments.
Review these carefully if the update asks for new access to location, microphone, or household activity data.
How often should you check for updates?
There is no universal schedule, but a monthly check is a practical habit for most households.
You should also check after a manufacturer announces a security fix, a major app update, or a known device issue.
If your appliance is part of a larger smart home platform, review updates when you change routers, replace phones, or add new automation tools.
For high-use appliances, staying current reduces the chance of connectivity glitches and improves long-term reliability.
For newer devices, updates can also unlock features that were not available at purchase.
What to do if your appliance no longer receives updates
Some older models eventually reach end-of-support status.
When that happens, the manufacturer may stop releasing firmware updates even though the appliance still works.
Check the support page for the model number and look for lifecycle or end-of-service information.
If support has ended, consider reducing the device’s exposure by limiting internet access, disconnecting unused integrations, or replacing it with a current model that still receives security patches.
This is especially important for appliances connected to voice assistants, smart hubs, or home automation platforms.
