How do I know if this pressure sensor is the one for my boiler?

Verify the reference MU1033700 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part.

The pressure sensor measures the water pressure of the circuit for the electronics.

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 connector and the gasket.

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.

What does the F3 code mean in Fagor?

Circuit pressure out of range (low/high). The water pressure switch/transducer (MU1033700) may send an incorrect reading or fail to activate the contact, causing the PCB to detect low/high pressure and lock out. Verify by comparing the pressure gauge vs. display and measuring the sensor signal (≈0.5–3.5 V) or use a jumper/test spare part.
