Neal,
If you are referring to the hoses inside the machine they only have water pressure, and a limited amount at that, when the machine is filling with water. When the solenoids at the inlet valve shut off when the tub is full they have no pressure. When the tub is filling they are running free into the tub.
The braided hoses are much better than the straight rubber hoses. I can't say that I've seen a braided hose fail. Washing machine hoses failing are in the top 10 water damage events. Water heater and toilet failures are higher. Frozen pipes come in at 18%, higher in the frozen north.

Washing Machine Failure Risks
Washing machine-related failures are one of the top 10 leading sources of residential water losses. The typical causes are supply hose failures, machine overflows and drain line failures.
A multi-company and multi-region study of homeowners’ insurance claims from water damage caused by washing machines revealed:
These failures cost an average of $5,308 per incident after the deductible was paid.
Failures of supply hoses accounted for more than half of all washing machine-related losses.
Of the water supply hose failures resulting in water loss claims, 78% involved washing machines that were less than 11 years old. Of these failures, 54% occurred in washing machines between eight and 10 years of old.
The proportion of washing machine related claims to total water loss claims was 67% higher in South Region states than in North Region states.
The average claim severity for South Region states was 28% higher than North Region states.
Although the affect of washing machine location on claim frequency could not be determined in this study, in the North Region, claims for units located in basements were 24% higher than claims for units located on the first floor.
Approximately 6% of all washing machine failures occurred in unoccupied homes.
Failures that occurred in unoccupied homes resulted in claims that were on average nearly two-and-a-half times more severe than those occurring in occupied homes.
