3 Bar Safety Valve Hermann Micra Condens 26 Ref. H155600002
If you notice that your boiler is leaking continuously, a technical diagnosis must confirm whether you need the 3 Bar Safety Valve Hermann Micra Condens 26 Ref. H155600002. This valve is responsible for releasing water when the circuit pressure exceeds 3 bar, preventing damage to the system. If it fails, it does not discharge properly or may present leaks. It is compatible with the Micra Condens range, including the Micra Condens 26 model, among others. A technician must confirm through diagnosis whether it needs to be replaced when constant dripping or pressure issues are observed.

How to check if ref. H155600002 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 H155600002. If it is not visible, do not identify the part from 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 safety valve H155600002
The safety valve releases pressure when the circuit exceeds its setting. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
It drips or bleeds intermittently from the discharge pipe.
Cause: The seat does not close completely due to accumulated scale or a small residue of dirt in the interior passage.
Operate the bleed lever a couple of times to try to clean the seat before replacing the part.
- 02
The valve opens just when the circuit approaches 3 bar, even during normal use.
Cause: If the expansion vessel does not properly cushion the pressure increase, the circuit reaches the set limit sooner than expected.
Measure the air pressure of the expansion vessel with the boiler cold and empty before suspecting the gas valve.
- 03
It's difficult to maintain a stable pressure in the circuit: it rises and falls easily.
Cause: A valve that starts to fail releases small amounts of water each time the pressure rises, without visibly dripping.
Monitor the pressure gauge during a complete heating cycle and note if the pressure decreases progressively after each increase.
- 04
A ring of moisture or dry lime appears around the discharge pipe.
Cause: It is a sign that the valve has been leaking intermittently for some time, even though no active water is visible now.
Clean the area and check it again after a few days: if the stain reappears, confirm that the leak is still active.
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.
