Hi my name is***** will be glad to try to help. If the filter was plugged with metal/debris it is and indication of a pump or component failure. The contamination will go through the system, into the valves and components and cause further damage and problems. If metal was found you will need to flush and clean out the system and replace the failed pump or component. If clean then the next step is to have your pressures tested and confirmed they are within OEM specs and if not this process will help isolate the problem to either a pump, valve or other internal leakage problems. Let me know
