Thanks for your answer (I will see when it will happen) but I’m not sure that it’s that because the pump doesn’t start when the problem occures, the pump doesn’t produce any sounds, I just heard the “click” of the valve
The problem just happened now, the tube is not blocked, it worked fine but suddenly the pump stoped working. When I click on catch in Uclient, the pump doesn’t start, I can just heard a click but not the noise of the pump.
It happened after only 5 minutes of utilisation.
I unplugged and replugged the alimentation of uarm and it didn’t work.
I waited 10 minute and it was always not working, I tried to move the pump’s cables and It worked !
It seems that there is a faulty connection in the pump block …
