Ebm-papst Gas Valve For Viessmann Vitodens 100-W Ref. GB-NO 055 E01 S00
Gas block manufactured by ebm-papst, as stated printed on the label ('Made by ebmpapst'). It regulates the gas flow to the burner in Viessmann Vitodens 100-W B1HC and B1KC boilers of 19 and 26 kW. Replacement requires first confirming the fault of the part through technical diagnosis, even when the boiler does not ignite or is locked due to a gas supply fault.

How to check if the reference 7861580 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 7861580. If it is not visible, do not identify the part by its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms that require diagnosis in the gas valve 7861580
The gas valve regulates and modulates the gas flow to the burner. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite and remains locked because gas is not reaching it.
Cause: The gas block does not open the passage to the burner.
Check that the gas valve is open and that power is reaching the control board before replacing it.
- 02
A buzzing or strange noise is heard in the area of the gas block.
Cause: The internal coil vibrates due to a power supply fault or a shutter that does not seat properly.
Check that the connection wiring to the block is not loose or damaged before replacing the part.
- 03
There is a smell of gas near the block, even though the boiler is working.
Cause: A joint or connection of the gas block is losing tightness.
Locate the exact point with soapy water; it could be a loose joint, not the entire block, before replacing it.
- 04
The boiler repeatedly locks out when trying to start.
Cause: The unit does not provide the necessary gas flow for flame detection.
Check the gas pressure in the installation before assuming that the block is faulty.
Viessmann fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| F8 | Burner fault: the (combined) gas valve closes too late. | A faulty gas valve delays its closure during the safety test, and the control detects it and locks out. Check in service mode/minimum power by observing the closure delay, measuring the signal to the valve, and performing a tightness/closure test. |
| F4 | Burner fault: no flame signal (ionization not detected). | If the gas valve does not open or delivers insufficient flow, the flame is not established and F4 appears. Check by measuring voltage at the valve coils during ignition and the gas pressure/flow; confirm opening from the service menu/function. |
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
