Maytag MVW5430 top-load washer will not connect to Wi-Fi or the manufacturer's app

The checks in more detail

If the indicator never flashes, the washer may not be in setup mode, so repeat the steps. Make sure the washer lid is closed, that the washer is awake and that the Remote Enable setting is on, since the app can only start a cycle if the washer is set to allow it. The router matters. Most appliances join only the 2.4 GHz band, so connect your phone to the 2.4 GHz network for setup, or turn off a merged band name for a while.

Use WPA2 and a simple password without unusual characters, and place the router within range; a laundry room far from the router or with a thick wall has a weak signal, so move the router, add a node or an extender near the washer. A router with MAC filtering or a guest network with isolation can block the washer. Reserve an address for it. If the washer joined once and now shows offline, restart the router and the washer by unplugging it for a few minutes, and reconnect.

Update the app and the washer's software; the app prompts for updates. If you changed your router or password, the washer must be set up again. The washer's Wi-Fi light usually shows the state, such as solid for connected and flashing for searching, so check the manual's list. A power cut resets the connection. If it still will not join, reset the washer's network settings, as in the manual, and add it again in the app. Contact Maytag with the model number if setup never completes, and note that the washer works fully without Wi-Fi.
