I replaced the filler hoses because an "aneurism" threatened to burst.
I used metal clad hoses by Flood Protection. Expensive, but I assumed a
good product. Although the hot water worked fine, no cold water was
getting to the washer. Others on this group offered suggestions, all
good, but none helped.
It turns out that this brand has a built in automatic cutoff if the flow
is greater than 3.5 gpm and considers this evidence of a hose burst.
To restore it, the hose must be disconnected from the supply.
GF discovered all this by reading the tags on the hoses!
