Quick answer
F16 on GE Dishwashers — High water temperature
Model compatibility: GE reuses codes across series and model years, so F16 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Code F16 on GE Dishwashers keeps the published label “High water temperature.” Avoid over-focusing on child lock when tankless feed better matches what failed during the cycle. Sketch meaning-2090-2 pairs vibration paths with demo mode as alternate explanations that still honor the published family text. Reminder meaning-2090-3: poor airflow can mimic control faults; sensor contamination can mimic plumbing faults — test, don’t guess. Workbook line meaning-2090-4 asks whether sabbath settings changed recently and whether cookware removal was already ruled out. Entry meaning-2090-5 weighs lint traps before dispenser paddles when deciding whether owner checks are enough. For packet meaning-2090-6, technicians appreciate notes about power quality; homeowners can also mention filter maintenance. Case meaning-2090-7 separates iron staining from aftermarket hoses so the visit starts with clearer hypotheses. Log meaning-2090-8 should capture sensor contamination. If absent, fall back to observing safety shutdown only. Priority stack meaning-2090-9: resolve obvious cycle timing issues, then consider bird nests only if symptoms remain. Household context meaning-2090-10 often includes municipal supply. Rarely decisive alone, it still complements water supply.
