When using water dispenser there is a loud banging noise. I replaced the water filter and the dual inlet valve. The noise was still there after replacing both parts. Took the filter out and reinstalled and the noise stopped for a short time then returned. When the noise is present the water flow is greatly reduced.
Try turning the water pressure down, Then slowly turn it uo till the banging starts, then back it out a half or quarter turn.
