Beko WM5100W

Hi,

Be very careful here, because the pressure switch wiring can vary and getting it wrong can cause overfilling, no spin, or damage to the control circuit. Isolate the washing machine from the mains before checking any wiring.

A few sensible checks:

1. Do not rely on generic internet photos Even if it looks the same, Beko used different pressure switches and looms across similar models. The safest guide is the machine’s own wiring diagram, usually found inside the cabinet, behind the fascia, or attached to a side panel.

2. Identify the pressure switch terminals A 3-terminal pressure switch is usually a common, normally closed, and normally open arrangement, but I would not want to guess which pin is which on your exact part. The terminal markings may be stamped on the switch body itself, such as C, NC, NO, or numbered terminals.

3. Compare old and new parts If you still have the original switch or loom, compare terminal markings and wire positions directly. That is by far the best method.

4. Use a continuity meter With the tube disconnected and then gently blowing into the switch, check which terminals change state. That will tell you the common and switched contacts. Then match that to the machine wiring diagram.

5. Check the air tube as well Make sure the pressure hose is fitted, clear, and not split. A blocked or leaking tube will cause level faults even if the wiring is correct.

If you can post clear close-up photos of the switch terminals, wire colours, and any markings on the switch, I can help you narrow it down. If there is no wiring diagram, I’d strongly recommend a qualified appliance engineer rather than guessing, especially for mains-related wiring.
