CDA CW446

done a search for this fault i’m getting on this d/washer, and somebody said to check the water flow switch, but this m/c does no have one, I’ve seen them on the w/pool models, in the sump on r/h side. But I’m getting the classic fault of this d/washer drains out at start, then immediately shuts done, and pulse’s on fill, and drain till the cows come home. There is no fault code comming up, and I’ve noticed whatever prog has been selected that light constantly flashes.
I checked all the working components, and for broken wires etc, the air chamber, p/switch etc,etc. But cannot find a fault.
Any other info on this problem would be welcomed.
