I have an 3100 gl Intexpump, witch until today has been working without problems.
Today when i went out to put the vacuum in, it didn't move at all. I felt the flow comming back to the pool, and there was allmost none of it. The pump it self is working, but something is wrong with the flow. I tried to make a longer backwash and a longer rinse, and it seemed like it worked for 5 seconds, and the vacuum was running, but then it stopped again.
What can be wrong??
