Appliance Repairs Job - Pinehurst, WC, 7550

Have a Whirpool front loader. Leaking water from dispenser. Had 2 separate companies look at it. One just couldnt find anything wrong with drainage system, only deep cleaned it afterwards. But soon same problem persists. Had someone else look at it, they couldnt find anything wrong, pipes all in tact and clean. Somethimes it leaks a bit, sometimes not. Mostly when water supply on and drum spinning fast, mainly start of rinsing.
