Extractor Baxi Roca Laura 30 30 F Ref. 122220170
Gas boiler flue extractor Roca Laura. On the mounting plate, there is only a handwritten mark '40', which corresponds to a batch or internal control marking, not a factory reference. It is the part responsible for expelling combustion gases. The replacement requires first confirming the fault of the part through technical diagnosis, even when it fails, makes noise, or causes the boiler to lock.

How to check if ref. 122220170 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 122220170. 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 extractor 122220170
The extractor evacuates the combustion gases with forced draft. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The extractor makes a bad sound, with vibration or buzzing, when starting the boiler.
Cause: The wear of the impeller or the bearing generates that noise over time.
With the boiler unplugged, move the impeller by hand: if you notice friction or play, the wear is confirmed.
- 02
The boiler does not ignite or locks out immediately upon trying.
Cause: If the extractor does not provide the minimum flow rate, the pressure switch does not close and the control board cuts off the ignition for safety.
Before changing the part, check the flue pipe for any blockages or improper installation.
- 03
The impeller rotates with difficulty or remains stationary when the ignition command is given.
Cause: After months of not using the heating, the shaft may seize up due to dirt or lack of use.
Try turning it by hand with the boiler off; if it starts with just a push, it's a seizure and not a burnt motor.
- 04
The boiler operates intermittently, sometimes it ignites and other times it locks out.
Cause: A fan that loses flow rate variably causes irregular blockages.
Check if the fault coincides with days of strong winds, which would point to the duct and not the extractor.
Fault codes Roca that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 20 | Insufficient pressure in the pressure switch or flue thermostat. | The flue gas extractor (fan) does not start or spins without providing flow, so the pressure switch does not close and the electronics block the ignition; verify by listening/observing pre-ventilation, measuring voltage at the motor terminals, and checking the venturi/tubes of the pressure switch. |
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.
