Troubleshoot BrewZilla WiFi or Registration issues

Wifi, Registration and Telemetry Issues

Problem	Solution
Cannot open Captive Portal	Check that WiFi is active on your mobile device
	Select KegLand RAPT XXXX network
	Enter password 'kegland1'
Cannot see KegLand RAPT XXX in my list of available networks	Navigate to Settings and Enable WiFI
	Unplug the device for 30 seconds, then plug it back in and refresh the list of networks on your mobile device
	This may already be connected to WiFi. Check the IP (STA) in Diagnostics. If this is populated with an IP address that is not 0.0.0.0 then this is already connected
"Selected Network is not connected to the Internet" error	Select the KegLand RAPT XXX network and choose "Forget This Network"
Device does not connect to my WiFi network	Check that your network is broadcasting a 2.4gHz signal
	Non alphanumeric characters in the SSID or password can cause issues - change these to simple (letters and numbers only) characters
	Ensure you are selecting the correct network and inputting the correct password for that network
	The network must have a password – the device cannot connect to an unsecured network
	The device may already be connected. Check the IP (STA) in Diagnostics. If this is populated with an IP address that is not 0.0.0.0 then the deviceis likely already connected
	Reboot the device by unplugging for at least 309 seconds
	Reboot your modem/WiFi router
	Try connecting to a different WiFi network
	Turn off any VPN or anything that can block an outgoing signal on the router
Cannot see a Validation Code	Connect the device to your WiFi network
	Update the firmware - select Check for OTA update in Settings
Error when Registering device	Check that the device firmware is up to date - select Check for OTA update in the DIagnostics screen
	The Validation Code may have timed out. Reboot the device by unplugging it for at least 30 seconds, then plugging it back in. Log out of the RAPT Portal and log back in
	If the above steps do not work, reboot the network that the device is connected to. Once the network has rebooted, reboot the device by unplugging it for at least 30 seconds, then plugging it back in. Log out of the RAPT Portal and log back in. Note: if using a modem and seperate wifi roters, reboot the modem and then the wifi routers in that order.
	A corrupt firmware install can prevent registration. This can happen if a firmware download is interrputed, for example. If the above steps do not allow registration, please refer to RAPT Device Boot Loop Troubleshooting & Recovery Mode to rollback firmware to a good version, then update to the current version
Determine whether your device is connected to Wi-Fi	To check this navigate to Diagnostics and check that it shows your network’s IP address next to IP (STA) - in the form 192.168.XX.XXX or similar. You can also check the WiFi AP (Access Point ) the device is connected to and the current WiFi signal strength
Determine whether your device is registered to the RAPT Portal	If the message "Register your device by pressing the select button to enter the main menu, then selecting the "Register Device" item in the main menu" is displayed, this is not registered. Please follow the steps outlined in Register Device
Cannot update firmware | 5379 Error	This is a network issue. The OTA Firmware Update could not be validated or was incomplete. Ensure your device is as close as possible to the router. Check signal strength in Diagnostics
	Ensure you have a strong 2.4gHz WiFi signal (not just 5gHZ). Check your signal strength against this table
	Make sure there are no VPNs in use, or filters or other potential issues set up in the router that can block an outgoing signal
	If issues persist, reboot the device and also the modem
Cannot update firmware | 28674 Error	This is a network issue. The OTA Firmware Update could not be validated or was incomplete. Ensure your device is as close as possible to the router. Check signal strength in Diagnostics
	Error 28674 is an error opening an HTTP connection. Check your modem or router settings. A VPN, Firewall or other setting may be blocking outgoing connections - this is a common reason for this error
	Ensure you have a strong 2.4gHz WiFi signal (not just 5gHZ). Check your signal strength against this table
	If issues persist, reboot the device and also the modem

General Troubleshooting

Problem	Possible Cause & Solution
Pump not working	Pump is blocked. The most common reason for a BrewZilla pump to stop working is due to blockage. The pump is easily accessible so the head can be removed and cleaned/unblocked. To prevent pump blockages always use the top screen when mashing or elevate the recirc tubing above the grain bed. Using the ball valve to control recirc speed can also help. If the recirc tubing contacts the grain bed it is common to have grain 'sucked back' into the pump causing blockages. Refer to Pump Cleaning and Maintenance for more information
	Cavitation. Cavitation during the boil can cause an airlock in the pump. Cycle the pump on and off briefly to clear this.
	Not cleaned properly. If the pump is not thoroughly cleaned after every use then sticky wort build up can cause the pump to fail or stop working. Ensure that hot (~50°C) StellarClean PBW solution is recirculated for at least 10 minutes after every brew day to prevent sticky wort buildup.
	Check for blockages. To determine if the pump is faulty or blocked remove the pump head when the BrewZIlla is empty and cool enough to handle. Inspect inside the pump head for grain or hop matter and clean as required. If not blocked, check to see if the impeller is spinning freely - sticky work buildup may prevent this
BrewZilla making a clicking noise in operation	This is normal. The elements are controlled by robust relay switching and thus clicking will be heard when the power is set to less than 100%
Mash temperature is different to probe temperature	This is normal. Due to grain having a large thermal mass the grain bed will not respond to temperature changes as quickly as the free flowing wort near the elements. Use of a RAPT Bluetooth Thermometer allows for precise and accurate control
Temperature reading error	Calibration issue. Select the Forget Calibration option from Settings to restore default calibration settings. If this clears the error re-calibrate following this guide. Ensure that the two calibration points are at least 20°C apart to minimise errors
Temperature reading not correct	Calibration issue. Select the Forget Calibration option from Settings to restore default calibration settings. If this clears the error re-calibrate following this guide. Ensure that the two calibration points are at least 20°C apart to minimise errors
