What indicates that a hydraulic pump may have a problem?

A popped filter button is an important indicator that a hydraulic pump may be experiencing a problem. The filter button serves as an indicator for the condition of the hydraulic fluid filtration system. When the filter becomes clogged due to contaminants within the hydraulic fluid, the pressure differential builds up, causing the filter button to pop. This situation signifies that the fluid is unable to properly circulate through the system, which can lead to reduced performance or failure of the hydraulic pump. Monitoring the condition of the filter buttons is essential for ensuring that the hydraulic system remains functional and that potential issues are addressed before they lead to serious system malfunctions.

The other indicators, while important in their own right, do not directly signify a specific problem with the hydraulic pump itself. For example, clean filter buttons indicate that the filtration system is working well, low fluid levels can suggest a leak or that maintenance is required, and a change in fluid color can indicate contamination but does not directly correlate to immediate issues with the hydraulic pump's functionality.
