You need to do several of the previously mentioned things,
1) Get a larger dehumidifier. They are rated by the quarts per day that they can theoretically remove. Mine is a 70qt and works well in a 1500sqft basement.
2) one fan on opposite side of the basement from dehumidifier aimed across the space to move the air. Low to medium speed is fine. Just slowly mixes the air and removes the dead spots.
3)Make sure the dehumidifier is piped into the sump and runs 24/7 at whatever setting you choose. I sat mine at 40%. When you first start, it is going to run day and night for several days to weeks but eventually, it will slow down when the dehumidifier gets caught up. You’re pulling humidity out of every object in the basement so it will take a while.
4) And if possible, Drylock the cement walls and floor to decrease the ingress of moisture from below the pad and the soil against the foundation.
Best of luck!
