Hydraulic pressure too low
on Gildemeister CNC
Hydraulic pressure is not enough for the chuck, the tailstock or a tool change. The machine stops, or does not clamp properly.

// Why we narrow it down by phone
Error codes are context-dependent. What is the right response on a CTX 400 with EPL2 would cause a second failure on a GDM with Eltropilot. Instead of a half-truth guide, we publish only the component class here — the real diagnosis we do by phone, in 5–10 minutes, free of charge and without promises.

Where the code appears.
All Gildemeister lathes with a hydraulic system (CT, CTX, GDM, MD, TWIN, GMX).
What the code means specifically on your machine depends on the year of manufacture, the control, the configuration and any previous maintenance. From 30 years of workshop experience we know the typical patterns — we place them for you over the phone.
Please note first
What you should not do yourself.
In most cases it is the sensor, not the pump. Replacing the wrong pump costs four to five figures.
In concrete terms: before any repair on a Gildemeister CNC, back up the parameters and NC programs. Replace a component only after a diagnosis, never on a hunch. If you are unsure: call us. Those 5 minutes often save a four-figure mistake.

// FREQUENTLY ASKED QUESTIONS
What does hydraulic pressure too low mean on a Gildemeister?
Hydraulic pressure is not enough for the chuck, the tailstock or a tool change. The machine stops, or does not clamp properly.
Which Gildemeister machines are affected?
All Gildemeister lathes with a hydraulic system (CT, CTX, GDM, MD, TWIN, GMX).
What is usually behind it?
From 30 years of workshop practice: usually the pressure sensor, the hydraulic pump, the filter, the oil level or the seals. An exact diagnosis requires a machine-specific workshop check or a preliminary phone diagnosis with ESDI.
What should I NOT do myself?
In most cases it is the sensor, not the pump. Replacing the wrong pump costs four to five figures.
