How may a technician narrow down this problem?
A technician will usually separate simple operating, airflow, water, power or installation issues from an actual component failure. For dishwasher not draining, the first checks focus on the conditions that match your symptom instead of replacing parts by guesswork.
A technician may start by confirming the complaint under normal operation, then work through likely causes such as filter or sump obstruction, drain pump problem and kinked or blocked drain hose. If those checks do not explain the problem, deeper electrical, control, mechanical or sealed-system testing may be needed depending on the appliance.
