Bosch Rexroth supplies drives and controls (IndraDrive, DIAX and EcoDrive servo systems, IndraMotion and IndraControl) and hydraulics, including proportional and servo valves and their amplifier electronics.
Common faults
What usually fails on a unit like the 3DREPE 6B-2125EG24N9K31/A1M=00
Proportional and servo valves, their amplifier cards and actuator controls link electronics to hydraulics. Faults can sit in the valve's coil or electronics, the amplifier card or the hydraulics, and each is checked separately.
Amplifier card faults
Failed output stages or supplies on valve amplifier cards cause no movement or full-on valves.
On-board valve electronics
Integrated electronics fail through heat, vibration or supply surges.
Coil failures
Open or shorted solenoid coils.
Contamination
Dirty oil causes sticking spools and erratic control, which can look like an electronics fault.
Feedback sensor faults
Spool position and pressure feedback sensors giving wrong signals.
First checks
What to check before calling an engineer
Isolate and lock out the supply, and wait for stored energy to discharge, before opening anything.
Safe for plant staff
- Check the command signal and supply to the valve or card.
- Check oil condition and filters.
- Note whether movement is absent, erratic or stuck at one end.
Leave to a specialist
- Valve electronics and amplifier repair.
- Setting gain, offset and ramps.
- Work on pressurised hydraulics.

FAQ
3DREPE 6B-2125EG24N9K31/A1M=00 repair questions
Does the valve need to be sent with the Rexroth 3DREPE 6B-2125EG24N9K31/A1M=00?+
For an amplifier card, not necessarily; it can be tested on a load. Send the valve too if it has integrated electronics or the fault might be in its coil or feedback.
Does the Rexroth 3DREPE 6B-2125EG24N9K31/A1M=00 have to be sent in, or can an engineer come to the plant?+
Either. An engineer can diagnose it in place and repair it there or take it away, or the unit can be sent to MachineryFix from anywhere in India. The diagnosis and repair cost are confirmed before any work starts.
Is MachineryFix connected to Rexroth?+
No. Rexroth and the model name are used only to identify the equipment. MachineryFix is an independent repair service and is not affiliated with or endorsed by Rexroth.
