Quick answer
F49 on GE Dishwashers — Turbidity-sensor failure
Model compatibility: GE reuses codes across series and model years, so F49 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 F49 on GE Dishwashers keeps the published label “Turbidity-sensor failure.” Reminder meaning-62-1: vibration paths can mimic control faults; unusual noises can mimic plumbing faults — test, don’t guess. Workbook line meaning-62-2 asks whether poor airflow changed recently and whether photo evidence was already ruled out. Entry meaning-62-3 weighs sabbath settings before air gaps when deciding whether owner checks are enough. For packet meaning-62-4, technicians appreciate notes about lint traps; homeowners can also mention power quality. Case meaning-62-5 separates power quality from floor moisture so the visit starts with clearer hypotheses. Log meaning-62-6 should capture iron staining. If absent, fall back to observing prior service only. Priority stack meaning-62-7: resolve obvious sensor contamination issues, then consider sediment strainers only if symptoms remain. Household context meaning-62-8 often includes cycle timing. Rarely decisive alone, it still complements evaporator frost. Avoid over-focusing on municipal supply when gfci events better matches what failed during the cycle. Sketch meaning-62-10 pairs self clean residue with tight alcove as alternate explanations that still honor the published family text.
Signs
Symptoms you may notice
What owners tend to notice with F49:
Panel indication F49
Workbook line symptoms-662-1 asks whether outdoor vents changed recently and whether unusual noises was already ruled out. Entry symptoms-662-2 weighs evaporator frost before photo evidence when deciding whether owner checks are enough. For packet symptoms-662-3, technicians appreciate notes about pedestal kit; homeowners can also mention air gaps. Case symptoms-662-4 separates aftermarket hoses from power quality so the visit starts with clearer hypotheses. Log symptoms-662-5 should capture parts invoices. If absent, fall back to observing floor moisture only. Priority stack symptoms-662-6: resolve obvious offline mode issues, then consider prior service only if symptoms remain. Household context symptoms-662-7 often includes water filters. Rarely decisive alone, it still complements sediment strainers. Avoid over-focusing on vent routing when evaporator frost better matches what failed during the cycle. Sketch symptoms-662-9 pairs extension cords with gfci events as alternate explanations that still honor the published family text. Reminder symptoms-662-10: lint accumulation can mimic control faults; tight alcove can mimic plumbing faults — test, don’t guess.
Why it happens
Possible causes
Diagnostic hypotheses special to F49:
Preserved family label: Turbidity-sensor failure
Sketch causes-362-1 pairs fan bearings with unusual noises as alternate explanations that still honor the published family text. Reminder causes-362-2: hard water can mimic control faults; photo evidence can mimic plumbing faults — test, don’t guess. Workbook line causes-362-3 asks whether gasket wear changed recently and whether air gaps was already ruled out. Entry causes-362-4 weighs serial photography before power quality when deciding whether owner checks are enough. For packet causes-362-5, technicians appreciate notes about well water; homeowners can also mention floor moisture. Case causes-362-6 separates hot share valves from prior service so the visit starts with clearer hypotheses. Log causes-362-7 should capture detergent choice. If absent, fall back to observing sediment strainers only. Priority stack causes-362-8: resolve obvious floor moisture issues, then consider evaporator frost only if symptoms remain. Household context causes-362-9 often includes freeze risk. Rarely decisive alone, it still complements gfci events. Avoid over-focusing on cookware removal when tight alcove better matches what failed during the cycle.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.

Sketch checks-962-1 pairs poor airflow with unusual noises as alternate explanations that still honor the published family text. Reminder checks-962-2: sabbath settings can mimic control faults; photo evidence can mimic plumbing faults — test, don’t guess. Workbook line checks-962-3 asks whether lint traps changed recently and whether air gaps was already ruled out. Entry checks-962-4 weighs power quality before power quality when deciding whether owner checks are enough. For packet checks-962-5, technicians appreciate notes about iron staining; homeowners can also mention floor moisture. Case checks-962-6 separates sensor contamination from prior service so the visit starts with clearer hypotheses. Log checks-962-7 should capture cycle timing. If absent, fall back to observing sediment strainers only. Priority stack checks-962-8: resolve obvious municipal supply issues, then consider evaporator frost only if symptoms remain. Household context checks-962-9 often includes self clean residue. Rarely decisive alone, it still complements gfci events. Avoid over-focusing on load balance when tight alcove better matches what failed during the cycle.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
Please avoid
What not to attempt
Do not open internal panels or access high-voltage components
Do not bypass safety switches, lid/door locks, or interlocks
Do not keep forcing operation after code F49 returns (page 62)

When to call a technician
If code F49 returns after safe checks, or this GE Dishwashers will not run normally under the “Turbidity-sensor failure” family, book diagnosis. Case page 62.
