My dehumidifier sh3030 is not collecting water but is running fine

You say it's running "ok", but there is no water discharge. If that is true then you have absolutely no moisture in your air and that is practically impossible. So we can say effectively that it is NOT running "ok". Fell the discharge air from the unit. If it is roughly room temperature rather than substantially warmer that than the air in the room, then you have found a problem. That problem would be that while the fan may be running, the compressor that heats that air and gets the condensation going is not. If you feel little or no air from the discharge, then you could have a clogged coil or filter (you checked that), or a bad fan.
