Recently, the spinning nozzle has stopped giving a spinning jet. At first I thought that something got into her and it should be blown with air from two sides. It worked, but for a short time. The pump interrupted operation periodically with this nozzle, the periods of interruptions were short, but after resuming work the stream did not spin. I bought a new spinning nozzle. I put it on and for over three hours it gave a swirling stream though it seemed like weaker. After three hours of work, after another insertion (I replaced it periodically with a vario nozzle to rinse / sweep away the dirt from the washed stone) again the same problem. It doesn't spin, it only gives one stream and the pump stops. Strange, new nozzle, could I buy a faulty or maybe some problem with the pressure pump. I have some sand in the water I see, which can be seen on the annually cleaned wash basin filters. Could this be the reason he could get into the pump? Or maybe it 'blocks' the right flow of water and there is no proper pressure? And this may be the reason for incorrect operation of the rotating nozzle?
