We do not publish specific diagnostic steps.
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 main spindle.
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.
If a full overhaul is due: the procedure and scope of our spindle repair — including a test run on the test bench with a function test report.
Please note first
What you should not do yourself.
Replacing spindle bearings without a preliminary diagnosis costs four figures. Often the cause is not the spindle itself — but the tool or the clamping device.
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.
