PDF manuals and 17 models in the SR Universal, Optimajor and S10 ranges. Verified codes and indicators for the Hydrostat 3250-Plus control.
These official documents cover the US market. Each range links to its manual and brochure. These PDFs do not contain a separate code table for every model: faults depend on the installed control or burner.

Accessories, burner and venting: these PDFs are not code tables for every Saint Roch boiler.
Hydrostat 3250-Plus messages only: SR S10/3 through S10/7, SR Optimajor OPTI GLP 6/8/10/12/14 and SR Universal with the LT kit. Confirm the control reference and version; the cited manual is for the 3250-Plus, revision 082625. These messages are not assigned to the 3250TC in WT-1/WT-2 kits or older Belgian ROKOR and ULTRA PF boilers. LEDs and Pur are labelled as indicators rather than fault codes. Burner faults require the burner’s own manual.
8 error codes found
Check the identification label accessible without dismantling, the invoice or maintenance report. Keep the range name and all suffixes: VCW 286 or TOP 22/28 alone may not be enough.
No. The ThemaCondens manual cited in our article associates F.22 with insufficient water or pressure. The older ThermoMaster F24E, FAS28E and F28E manual gives excessive pressure for F22. Check the model before topping up.
The subcode can distinguish different conditions. The official Bosch lookup cited in our article gives different descriptions for EA-227 and EA-511. Check applicability to your model; do not automatically apply those results to an older Junkers.
An ordinary radiator does not have a boiler diagnostic display. Identify the boiler or electronic controller actually showing the message, then look up its brand and model.
