the wifi keeps disconnecting on my smart dishwasher, i have to keep re-adding it in the app

Diagnosis

The Samsung Bespoke AutoRelease DW80B7070AP utilizes a compact Wi-Fi module tucked behind the control panel, which is shielded by a thick stainless steel chassis and often obstructed by the cabinetry and plumbing of your kitchen. This creates a "Faraday cage" effect, significantly attenuating the signal. When the signal strength (RSSI) drops below a certain threshold, the dishwasher's network interface card (NIC) drops the connection to prevent packet loss, causing the SmartThings app to report the device as offline. This issue is frequently exacerbated by "Band Steering" on modern mesh routers. The dishwasher only supports the 2.4GHz band. If your router attempts to force the device onto the 5GHz band or switches channels dynamically, the DW80B7070AP cannot hand off the connection seamlessly and will disconnect. You can confirm this by checking the "Device Status" in the SmartThings app; if the device disappears entirely rather than just showing "Offline," the module has likely crashed or lost its IP lease from the DHCP server.

How to Fix It

To stabilize the connection, you must clear the cached network credentials and force a fresh handshake with a dedicated 2.4GHz signal.

1. Open the SmartThings app on your smartphone, navigate to the dishwasher, select the three-dot menu in the top right, and choose "Remove Device."
2. Power cycle the dishwasher by flipping the dedicated circuit breaker in your home's electrical panel OFF for 60 seconds, then flipping it back ON. This clears the volatile memory of the Wi-Fi module.
3. At the dishwasher control panel, press and hold the "Heated Dry" and "Delay Start" buttons simultaneously for exactly 10 seconds. You will hear a confirmation beep and the display will indicate it is in pairing mode.
4. Access your router settings via a web browser and temporarily disable "Smart Connect" or "Band Steering." Create a separate SSID specifically for 2.4GHz devices (e.g., "Home_Wifi_2G").
5. Ensure your smartphone is connected to this 2.4GHz network. Stand directly in front of the dishwasher door to minimize interference during the initial handshake.
6. In the SmartThings app, select "Add Device" and follow the prompts to reconnect the DW80B7070AP to the dedicated 2.4GHz SSID.
7. Once connected, re-enable your 5GHz band for your other devices.

If That Didn't Work

• Install a Wi-Fi Range Extender or a Mesh Node within 10 feet of the dishwasher. Placing a node on the opposite side of the kitchen wall can provide a stronger line-of-sight signal to the dishwasher's internal antenna, reducing the RSSI drop-off.
• Assign a Static IP address to the dishwasher through your router's DHCP reservation table. Use the dishwasher's MAC address (found on the sticker inside the door frame) to ensure the router doesn't reassign the IP address every few days, which often triggers a disconnect in the SmartThings ecosystem.
• Change your router's 2.4GHz channel from "Auto" to a fixed channel, specifically 1, 6, or 11. These are non-overlapping channels; if your neighbors are all on channel 6, switching to channel 1 can eliminate the signal noise that causes the Bespoke module to drop.
• Check for electromagnetic interference. Ensure that high-powered appliances (like a microwave or a large air fryer) are not positioned directly between the router and the dishwasher, as these can disrupt the 2.4GHz frequency during operation.

Heads Up

• Avoid using special characters or spaces in your Wi-Fi SSID or password, as the Samsung Wi-Fi module can struggle to parse non-alphanumeric characters, leading to intermittent authentication failures.
• Keep your SmartThings app and the dishwasher's firmware updated. Samsung frequently releases "OTA" (Over-The-Air) updates that specifically improve the stability of the network module.
• If the dishwasher consistently disconnects after a power surge, the Wi-Fi module may be failing. Check for any signs of moisture or corrosion around the top control panel area.
• Remember that the "AutoRelease" door feature relies on a stable connection for remote triggering; if the Wi-Fi is unstable, the door may not open automatically at the end of the cycle via app command.
