Troubleshooting

The device's physical buttons, the two reset types, and answers to the most frequent problems.

The device's physical buttons

The device has two buttons: START/STOP and MODE. Besides their normal function, combined they trigger the administrative actions:

WiFi Reset vs. Factory Reset

• WiFi Reset — erases only the network credentials. The device returns to its factory network (BombaAgua-XXXX / bomba1234) but keeps your calibration, thresholds and schedules. Use it when you change routers or WiFi passwords.
• Factory Reset — erases absolutely everything and leaves the device as it shipped. Use it to sell it, gift it, or link it to another account.

Knowing how long you've been holding

The device signals progressively while you hold both buttons:

Common problems

The app can't find the device while pairing

• Turn on the phone's Location (GPS) — Android requires it to scan WiFi networks.
• Turn off mobile data temporarily: some phones try to reach the internet over 4G and ignore the device's network.
• Wait for the device to finish booting (a few seconds after power-up).
• Get closer to the device.
• If nothing works, connect manually: WiFi settings → BombaAgua-… network → password bomba1234 → back in the app tap "I'm connected to the device".

I typed my WiFi password wrong during pairing

If the device can't join your network, it returns to its own network by itself. In the app tap "Reconnect to the device (AP)" and repeat the step — double-check the password this time.

"This device is linked to ANOTHER account" (when turning on the cloud from Settings)

The device itself remembers which account it was linked to — that data lives in its internal memory. If you try to enable the cloud with a different account than the one it already has saved, do a Factory Reset to link it to yours: hold MODE + START/STOP for 10 seconds and confirm (see the table above). Wiping its memory makes the device forget the previous account and accept yours.

"This device is already linked to account e***@..." (when pairing it for the first time)

This is a different notice from the one above, and shows up when pairing a device for the first time in the app — typically if you bought it second-hand or lost access to the account you linked it with before. Here the link doesn't live on the device, it lives on our server, so a Factory Reset does not release it.

If that account is yours, sign in with it and unlink the device from "My pumps". If you can't sign in but you have the device physically with you, you can claim it — the app walks you through it. See "Recovering a device" in the Sharing & cloud chapter.

The app says "No connection" on launch

• Device on its private network: check that the phone is on the device's network (the app tries to connect by itself, but some phones jump back to their usual WiFi).
• Device on your WiFi: check the phone is on the same network. If the device's IP changed, use "Search my WiFi network" from the device list.
• Away from home: you need the device linked to the cloud and internet on your phone. If the app offers "Force cloud connection", try it.
• As a last resort, the app offers "Re-pair device".

The device shows "offline" in the cloud

The cloud works but the device isn't reporting. Typical causes: power cut at home, home internet down, or the WiFi password changed. The app shows the last known data meanwhile. If you're at home, join the same network and you'll have normal local control even without internet.

The pump won't start in Auto mode

• Level above the threshold? It only starts when the level drops below your configured threshold.
• Block schedule active? The main screen shows a notice. During a block, automatic starting is paused (manual stays available).
• Cistern out of water? With the cistern sensor enabled, the pump won't start if the source is empty.
• Minimum pause between starts? After stopping, the pump waits out the configured rest before starting again.
• Pending fault? If "⚠ Acknowledge fault" is showing, check the cause and tap it to re-arm.

The level in the app doesn't match reality

• Review the calibration (minimum and maximum distances) under Settings → Pump & sensor.
• Make sure the sensor has a clear line of sight to the water — no cables, cobwebs or obstacles.
• Erratic readings with a long cable: use shielded cable and route it away from high-voltage lines.

I updated the firmware and can't see the device

After updating, the device restarts on its own — it takes a minute or two to come back. If you were on its private network, your phone may have switched networks meanwhile: reconnect and open the app.
