John Deere 1713.15 – EPC, UIC, or BCU: Hydraulic Oil Filter Dirty

The filter alarm level 1 switch at the hydraulic oil filter remains closed for more than three seconds when the hydraulic/transmission oil temperature is above 28°C (82°F) and the engine speed is above 700 rpm, indicating the filter is restricted.

1. 1

   Verify operating conditions: Ensure the code triggers under normal operating temperatures (above 28°C/82°F), as cold, thick oil can cause false pressure spikes.

2. 2

   Inspect the filter housing and associated lines for physical damage, crimps, or blockages.

3. 3

   Check the differential pressure switch and wiring to ensure it is not shorted to ground, which would falsely signal a closed switch.

4. 4

   Inspect for severe contamination: When removing the old filter, check for heavy metal shavings or debris that could indicate a failing hydraulic pump or internal transmission component.

1. 1

   Prepare the Machine

   Park the tractor on a level surface, engage the parking brake, lower all implements, and turn off the engine.

2. 2

   Change the Hydraulic Oil Filter

   Locate the hydraulic oil filter bowl. Remove the housing, extract the dirty filter element, and clean the inside of the filter housing.

3. 3

   Install the New Filter

   Insert the new OEM filter element and reinstall the housing with new O-rings (lubricated with clean hydraulic oil).

4. 4

   Check Fluid Levels

   Verify the hydraulic/transmission oil level and top off with John Deere HY-GARD (or BIO-HY-GARD II) if necessary.

5. 5

   Monitor and Test

   Start the engine and allow the hydraulic oil to warm up above 28°C (82°F). Run the engine above 700 rpm.

6. 6

   Clear Codes

   Reset the system/clear the fault codes and operate the hydraulic functions to ensure normal oil pressure and temperature are maintained and the code does not return.
