Can an error code on a Whirlpool Cabrio washer be caused by a simple issue like a kinked water hose?

Yes, a kinked or blocked water hose is a common cause of error codes, especially those related to water intake (LE). Inspect the water inlet hoses for any kinks or obstructions. Also, check the water supply valve to ensure it's fully open. Simple fixes like straightening a kinked hose or opening the valve can often resolve the problem.
