seems like these pumps have their share of problems. I wonder if it's worth getting one of these of just going with the KISS system like a simple submersible and a pressure tank?

Have one whit the next: FAULT: E19.1 Wait leaving power on Time 14:00 Can help me? 🫤

Up to this point how long has this pump been in service

[@ejRecording]

Is it possible the sensor could be dirty instead of broken? how often do these generally fail? i see they’re around 100$ to replace…

[@deankreutzer2745]

Love my esybox mini3 but it loses pressure and then cycles all the time. I even turn off both the incoming and outgoing valves and it slowly loses pressure. Any idea what the issue could be? Thanks!

[@ejRecording]

I’m having the same issue right now, did you find anything out?? Thanks !!

[@deankreutzer2745]

@@ejRecording No, unfortunately I haven't figured it out. Now that my irrigation season is done, I may take it to someone to look at. The only thing I can think of is that if there is an internal check valve, maybe it is malfunctioning?

[@ejRecording]

@@deankreutzer2745 so it’s doing it with all valves closed? mines doing that when valve opens, so I think it must be the (overpriced) pressure sensor.

[@deankreutzer2745]

@@ejRecording Mine does it when all the valves are closed. I've sent a email to their support, but no support yet!

I would suggest a leaking or sticking ‘non return valve’

[@rustylingenfelter5756]

Thanks for this video. My Mini 3 sat in a few inches of standing water (Ian) and then showed a BP1 error for the pressure sensor. I opened it up, disconnected the pressure sensor, dried everything out, cleaned the lower connection with alcohol and then put it back together. The BP1 error is gone and everything appears normal, but it shows 83lbs of pressure and the pump doesn't start. I did a factory reset and then tried different SP/RP settings as per the troubleshooting chart, but no joy. I assume the pressure sensor is bad. I bought a replacement Mini 3 to get me going, but I would like to repair this one to use with my rainwater catchment system. Is there an easy way to buy the pressure sensor? That DNA website is a bit too complex.

Hello after three years without any problems my DAB Esybox shows an error internal error short circuit to earth. What could that be? I didn‘t even touch it since it has been installed by a qualified company.

Bonjour, je sais que cela fait un moment que vous avez publié cette vidéo, j'ai la meme erreur que vous, pourriez vous me dire ou trouver le capteur de pression. Nous sommes en france, les pièces sont elles les memes. Merci par avance , j'espère avoir une réponse. Bien cordialement

Where is the check valve located? My pump has been heating up and they said I need to remove the valve.

[@dabpumpsusa]

Thanks for your question! The check valve on the ESYBOX Mini 3 is located under the access panel beside the screen. Use the 2mm wrench under the top cover of the pump to remove the two screws at the top, pry off the access panel cover, and you will see a port cover like what is on the intake and discharge of the pump. Make sure that the pump is fully drained, then, unscrew and remove this port cover, and the check valve is directly behind it, you can just pull it out.

[@fa619]

Ok got it. Is there an obstruction or broken part that I should be looking for that could be responsible for the heating issue?

[@dabpumpsusa]

@@fa619 Check to see if there is an obstruction or if anything looks broken, if not, reassemble the pump and check to see if it is cycling or if you have the same fault. If you do, please call our tech line at 843-797-5002, x. 4. Thank you

Hi. We have the bigger version easybox pump. It has developed a problem with pressure, set to 4 bar but only operating at 0,5. It has 60 000lt tanks which it feeds from, no blockages in pipes. Could it also be the pressure sensor and how do we replace it ?

[@dabpumpsusa]

Hi There, we will be publishing a video for the same replacement on the Standard Esybox in the next few weeks. Stay tuned!

[@wally6193]

how long was it in service before problems started appearing?

[@marinadriantotolniceanu2493]

Hy i am having a problem with my pump. When the water gets in the pump it starts leaking from a side. Do you know what the problem might be? Thank you.

[@dabpumpsusa]

Hi, thank you for sharing this issue. We would like to know more about it. Can you please email us at [e-mail]?

[@marinadriantotolniceanu2493]

@@dabpumpsusa I have sent you an email with the problem. I am waiting for an answer. Thanks.

[@TC-et7ug]

Anybody know the max inlet psi? My town pressure is 40 psi. Im trying to get away without installing a pressure regulator. I just don't have the room.

[@michaelnuttall5896]

Install a regulator and set it to around 30psi, then on the mini 3 just switch this little thing at the back around to flooded suction.

[@raisedindade1]

I love DAB pumps, but it's hard not insulting you if you're an actual DAB tech using slip joints on those fittings. I'm sure your supervisor wouldn't appreciate that. Tell us the correct wrench size(even if it's metric).

[@Pago77]

I had one of these and the controller went bad, took to dealer and they had a graveyard full of them unrepairable due to extortionate cost of parts. Replacement part was 70% of a new pump and they are not cheap. Better off buying cheap Chinese pumps last longer anyway.

[@ejRecording]

Thanks that’s great info

[@wally6193]

seems like a lot of thermo plastic in this unit.
