Poor suction not enough to vaccum pool and not pulling floatong deris into basket but good circluation- pressure - backwashed and cleaned filters

SOURCE: does this pump Dynamo DYN

Pumps don't need to be backwashed, some filters do. Sand and DE filters need to be backwashed when the filter pressure has increased to 10 or 11 psi. depending on the manufacturers recommendation. The cartridge filter cannot be backwashed but instead it is removed and a hose sprayer is used to clean out the dirty outside. Your pump does need to be primed so it is not trying to pump mostly air. Each time the pump basket area is low in water then it needs to be primed. You will know how low it can go before it needs to be priming by turning it on when it is low and if it cannot start pumping water at full rate then at that level of water it needs to priming. If it is pumping water at full flow and you turn it off it should not need re-priming because there is enough water in it to force the air through the system. I hope this helps.

you have probably hit a dead spot on the motor - try turning the motor by hand and then turn it on - maybe it will kick it.
dangerous to do it while the power is on but some people have had luck doing the same thing while the power is turned on.
