Hi my name is***** will be glad to try to help. Check the old filter internally by inspecting a sample of the filter media for fine metal/debris indicating a pump or component failure occurring. If ok then the next step is to inspect the relief valve cartridges and the control valve for proper operation. Please let me know the complete model and serial number and the results if you need more help.
