Pressure switch Halstead Best / Wickes LWCi Ref. 500609
When you turn on the heating, the Halstead Best / Wickes LWCi pressure switch activates to monitor the air or water pressure in your boiler. Its function is to authorize the operation of the boiler, ensuring that everything is in order. If this component fails, you will notice that the boiler does not start or gets locked, even if the pressure is correct, and the fault code 05E: Smoke pressure switch anomaly may appear. This pressure switch is compatible with boiler models such as Biasi Minox, among others. A technician should confirm through diagnosis whether it needs to be replaced when you experience starting or locking issues in your system.

How to check if ref. 500609 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 500609. 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 pressure switch 500609
The pressure switch controls the air or water pressure to authorize operation. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler is locking out or not igniting.
Cause: The micro switch does not close the circuit that allows ignition because it does not detect the necessary draft depression.
Check that the flue is not blocked, bent, or leaking, which could prevent the proper draft from being generated.
- 02
The boiler is showing a fault related to the flue or combustion.
Cause: This pressure switch controls the combustion draft pressure and blocks if the value does not reach the necessary threshold.
Check that the tubes connecting the pressure switch to the flue are properly fitted and free of accumulated condensation.
- 03
The boiler runs for a few seconds and then stops.
Cause: An unstable pressure reading during startup causes the pressure switch to open the contact halfway through the cycle.
Note if the fault coincides with strong winds or rain outside; this could indicate a problem with the duct rather than with the pressure switch.
Renova fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 05E | Flue pressure switch anomaly. | If the differential pressure switch (Huba 500609) does not switch when the fan starts, the PCB does not receive the draft test and locks the boiler; check with a differential manometer that the venturi reaches the minimum depression (e.g., MINOX ECO 24E ≥140 Pa) and verify the continuity of the pressure switch micro by applying real depression and checking tubes/venturi. |
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.
