How often should the water inlet hoses be replaced, and why?

The water inlet hoses should be replaced after 5 years of use to reduce the risk of hose failure. You should also periodically inspect the hoses and replace them immediately if any bulges, kinks, cuts, wear, or leaks are found. It is recommended that you record the installation or replacement date on the hoses for future reference. (Pages 4, 8, 18)
