The rinse of the washing machine pump while rinsing

Good afternoon! VEKO 6108 washing machine. It works perfectly, but there is a problem - increased pump noise in rinse mode. After the rinsing process is over, the pump turns on. For 40 seconds, the water is drained completely without noise. Next comes the supply - 1 min 45 sec, but with increased noise (roar). The noise may be in the first rinse. At the next wash go to the second rinse. Thanks for the answer.
