I have metered out the flow switch and get some funny readings. It appears to have 3 contacts on the connection plug, so I assume its some sort of micro-switch with a NO/NC/COM contact arrangement. I get continuity through two of the terminals and not the other, which I assume would be correct. The switch appears to allow air ( me blowing through it ) and the impeller inside moves around and is not jammed. When I meter this switch in normal operation with power on, I measure 240V AC on all three pins of the plug, so am a little confused as to what a real reading should be if the switch was working normally. I want to be sure that its defective before fitting a new one, as they cost over £20. Has anyone got a circuit diagram of the flow through sensor area of the machine or know how its is supposed to work please ?
