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 andMODE. Besides their normal function, combined they trigger the administrative actions:
| Action | Button(s) | Hold time |
|---|---|---|
| Turn pump on / off | START/STOP | Short press |
| Change mode (Auto → Manual → Semi) | MODE | Short press |
| Restart the device | MODE | Release when it reads "Suelta para reiniciar" — release to restart (3–6 s) |
| Allow file update | MODE | Release when it reads "Suelta para actualizar" — release to update (6–10 s) |
| Show the local access PIN | START/STOP | Release when it reads "Suelta para ver el PIN" — release to see the PIN (3–6 s) |
| WiFi Reset (back to factory network) | MODE + START/STOP | 5 seconds |
| Factory Reset (erases everything) | MODE + START/STOP | 15 s without letting go (at 10 s it enters confirmation) |
A short press is anything released within 2 seconds: no need to be quick. If the screen is off (it turns itself off after 5 minutes without changes), the first short press only wakes it — so you can check the level without starting the pump or changing the mode by accident.
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:
| Time | What the screen shows | If you release here… |
|---|---|---|
| 0–3 s | Silence | Nothing happens (grace zone). |
| 3 s | Reset WiFi / en 2s, en 1s("WiFi Reset in 2 s") | Nothing yet — it's the countdown. |
| 5 s | Suelta para / Reset WiFi("Release for WiFi Reset") | Runs the WiFi Reset. |
| 10 s | Borrar todo? / manten 5s("Erase everything? hold 5 s") | Enters the confirmation: the screen counts down (4s, 3s…). |
| 10–15 s | The countdown | Release and you'll see Cancelado / no se borro nada ("cancelled, nothing erased"); reach the end and Borrando todo... appears and the Factory Reset runs. |
And with MODE alone
MODE works the same way, but it's a separate ladder (don't mix it up with the two-button one):
| Time | What the screen shows | If you release here… |
|---|---|---|
| Under 2 s | — | Changes the mode: Auto → Manual → Semi → Auto. |
| 3–6 s | Suelta para / reiniciar | Restarts the device. |
| 6–10 s | Suelta para / actualizar | Allows a firmware update from the app for 5 minutes (the screen confirms it: Actualizar / desde la app 5min). |
| Over 10 s | Suelta para / cancelar | Nothing happens: it's the way out if you changed your mind. |
Common problems
First of all: open Settings → Check my installation. At a glance it tells you whether the sensor responds, the tank is calibrated, the cistern has water, how good the WiFi is and which protections are on — often the answer is already there.
The app can't find the device while pairing
- Turn on the phone's Location (GPS) — Android requires it to scan WiFi networks.
- If it still won't connect, turn off mobile data for a moment: the app already routes traffic through the device's network, but some phones insist on going out over 4G.
- 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 → passwordbomba1234→ back in the app tap "I'm already 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 device (AP)" and repeat the step — double-check the password this time.
"Confirm your email" (the link doesn't arrive, or it won't let me link the pump)
Without a confirmed email you can't link a device to the cloud, share it or accept invitations; using it on your network stays the same. If the link doesn't arrive:
- Check spam or junk mail (it comes from
noreply@tinajonpro.com). - In the "Confirm your email" notice tap Resend email (wait a minute between sends).
- Is the email misspelled? Tap Change email in that notice, or in Account.
- Once you've opened it, go back to the app and tap I've confirmed it.
The link expires after 24 hours and works only once: if it says "not valid", ask for a new one from the same notice.
"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 aFactory Reset to link it to yours: holdMODE + START/STOPfor 15 seconds without letting go — at 10 sBorrar todo? appears and counts down 5 more (see the table above); let go when it reads Borrando todo.... Wiping its memory makes the device forget the previous account and accept yours.
"This device is already linked to the 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 and 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 on 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
- Did the power just come back? After powering up, the device waits out the start delay (3 minutes from the factory) before letting Auto start the pump, to avoid the unstable voltage of the return. The app shows it as "Waiting for the grid to stabilize".
- Does the screen say
SIN SENSOR? With no level reading, Auto and Semi won't pump blind. Check the tank sensor cable (terminals 9–12). - 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.
- Mains out of range? On the model with power metering, the pump won't start while the voltage is out of range: the app says so on the ENERGY card and the device's screen shows
BLOQUEADA POR/VOLTAJE(blocked by voltage). Nothing to acknowledge: it starts as soon as the mains is back (see Power metering).
The level in the app doesn't match reality
- Review the calibration (full-tank and empty-tank 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.
