Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

CodeWhat does it mean?Cause and diagnosis (this part)
60-80-90Insufficient pressure in the pressure switch or flue thermostat.The air differential pressure switch does not close because it does not reach the required depression/pressure (blocked connections, dirty venturi, or fan without flow). Check by measuring the continuity of the micro and/or pressure with a U manometer at the pressure switch connections and inspecting the tubes/venturi.
40-50-80-90Pressure above zero in the pressure switch or flue thermostat.The pressure switch contact is closed at rest (poor tube connection, stuck diaphragm, or incorrect setting), so the electronics detect pressure before starting. Verify that the pressure switch is open at rest (multimeter) and that the connections are correctly crossed and clean.
19Waiting for the pressure switch to open.The PCB detects the pressure switch closed when it should be open before start-up (stuck contact or inverted tubes). Check the status of the micro (open continuity at rest) and the direction/cleanliness of tubes and venturi; if it remains closed, pressure switch (122160280) out of range.
20Pressure switch closing delay.After starting the fan, the pressure switch does not close due to lack of depression (blocked ports/venturi, fan without flow, or miscalibrated pressure switch). Check the contact closure when starting ventilation and the pressure in mbar applied to the pressure switch inlet.
How do I know if this pressure switch is for my boiler?
Verify the reference 122160280 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Huba part.
What is it used for?
The pressure switch controls the pressure/draught (of air in sealed systems) or water to authorize operation.
Is the boiler not starting or showing a draught fault?
If the fan spins but does not ignite, check the pressure tubes (loose/blocked), the diaphragm, and the fan.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
Check the tightness of the pressure pipes and the switching of the contact.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
