This is interesting! I bought one of these (hoses) for a new dishwasher that I installed about a year ago. Sometimes we get marginal operation, i.e. leftover food particles on the dishes after a cycle. I wondered if the hose could be restricting flow on the fill cycle so that there was less water than the appliance was expecting to have. But, if this was true, I would assume that the dishwasher opens the inlet supply valve for a fixed duration of time instead of measuring the accumulated water level prior to starting (working with control systems and understanding that water pressures will vary from one home to another, I would have assumed that the unit was working on level via direct measurement). Thinking back to the installation manual, I'm almost positive that I remember there being a requirement that the available flow of the water source is greater than "x" gpm. So, perhaps the hose is really causing our issues?
Love to hear any insights on this.
Funny how you can get trick-bagged trying an alternative, albeit seemingly safer product!
TTFN,
