How to check if ref. FA000170 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference FA000170. If it is not visible, do not identify the part from its shape alone.
2. Check the full boiler model on its data plate and look for it in the model associations on this page.
3. Compare the connections and physical body with the original part before installation.
4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.

Symptoms that require diagnosis in the pressure switch FA000170

The pressure sensor measures the water pressure for the electronics. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  The pressure on the display shows 0 or dashes, even though the circuit is full.

  Cause: The sensor does not send a signal to the PCB, which does not receive any pressure value and shows an error.

  Check for leaks in the circuit or in the safety valve before considering the sensor.

• 02

  The boiler locks out due to low pressure just after refilling the circuit.

  Cause: The sensor may be giving a false reading below the actual level, which causes the lockout even though the water is at the correct level.

  Check the pressure with a separate manometer if possible, to rule out that it is a reading issue and not a water problem.

• 03

  If I move the wiring of the boiler a little, the pressure reading changes immediately.

  Cause: This indicates a possible loose connection in the connector or in the cable of the sensor.

  Carefully move the sensor connector while watching the display, without forcing or disconnecting it while hot.

• 04

  The boiler does not start and gives a warning of low pressure, even though the circuit is properly filled.

  Cause: The PCB relies on the signal from the sensor to determine if there is enough water; if the signal is incorrect, it does not allow the start-up even if everything is correct.

  Bleed the radiators and confirm the actual pressure before replacing the sensor, especially if the installation is new or has just been tampered with.

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.
