Dishwashers: Common Failures and What to Look For

Dishwashers are among the most common appliances in residential kitchens and one of the more complex when it comes to water-loss claims. With water connections, internal hoses, solenoid valves, pump seals, and an electrical system all integrated into a compact cabinet, this product has a notably wide range of failure modes. When a dishwasher is involved in a loss, identifying the specific component that failed, rather than the nearest connection point, is what determines the value of the evaluation.

In this episode of Evidence to Answers, forensic engineer Ben covers how dishwashers are typically installed, the most common failure patterns seen in practice, from manufacturing defects in solenoid valves and hoses to installation errors, abuse-related damage, and wear on pump seals, and what experts look for during a product examination. This includes fracture patterns, deformation, corrosion, and evidence of leakage.

This video is for those involved in losses where a dishwasher is a factor. Documenting serial and model numbers, photos of the appliance and all connection points, and the installation date gives experts the best foundation for a complete and defensible evaluation.
