Troubleshooting

• Turn the device off and on once, wait 30 seconds, and refresh the phone’s Wi-Fi list.
• Stand near the device.
• Setup mode closes after about five idle minutes. Power-cycle to open it again.

See: Connect to Wi-Fi

• Go to http://192.168.4.1/ (not https).
• Turn off mobile data, and stay connected when the phone warns there’s no internet.

• Use the 2.4 GHz network, and check the name and password exactly.
• Guest networks with a sign-in page don’t work.
• If the signal at the device is weaker than −80 dBm, improve coverage.

See: Check the site

• Check the device has power and the site’s internet works.
• If the Wi-Fi password changed, update it in setup mode.
• Turn the device off and on once and wait two minutes.

• Prime the pump.
• Check the direction: chemical should move toward the wash.
• Check the suction line reaches into the container and the container isn’t empty.
• Isolate power and check the tubing is seated in the pump head.

See: Prime and run a pump

• Check that input and pump pair isn’t Disabled and the setting was saved.
• The signal must turn off and then on. After power-up or a Safety Stop, cycle the wash function once.
• Check the input is wired to the right controller output, and the output reads 24–120 V when on.

See: Set up wash triggers

• With Dispense until it turns off, the pump runs while the signal is on. Set its Safety limits, or use Dispense a set amount.
• Check the controller output isn’t stuck on.
• Safety Stop in Dispense Config, or Stop on DozaLink, stops the pump.

• Calibrate at the flow rate you use.
• Check the tubing setting matches the tubing color: white is Standard, black is Tire Shine.
• Replace worn tubing.
• With Dispense a set amount, check Amount each time and the dispensed amount shown under it.

See: Calibrate the pumps

• Open Activity and look for Missed scheduled dose. It shows the reason.
• Check the device has power and its clock is set. After a restart it needs internet, or Set clock from this phone in setup mode.
• On the device’s page, check that Schedule is on, the start date has passed, and the pump’s tubing and calibration are set.
• If DozaLink says the schedule is paused after unexpected restarts, it resumes after an hour, or when you save a change to the device.

See: Dose on a schedule

• An admin locked them. Make the change on DozaLink, or ask the admin to click Allow local controls.

• Read the message. Billing and Wi-Fi are the usual causes. Fix it and retry with the same label.
• A device belongs to one organization at a time. If it was used elsewhere, that organization must unlink it.
