Re: fisher & paykel dishwasher 918td, pump running, noon
A flow meter is a device containing a water wheel with a magnet embedded in it running in the water flow, and a reed switch (usually on a small pcb) mounted on the outside. The magnet passing the reed switch opens and closes it, thus generating pulses, which the computer counts and determines the water level from. There is no “re-set” for such a device. Failure of the reed switch is quite common, although it is worth checking for continuity through the wiring to the main pcb.
