Quick answer
CD on GE Washing Machines — Main electronic-control-board failure
Model compatibility: GE reuses codes across series and model years, so CD 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
Verified family for this GE Washing Machines page (code CD): Main electronic-control-board failure. Household context meaning-29-1 often includes poor airflow. Rarely decisive alone, it still complements app pairing. Avoid over-focusing on sabbath settings when spray arm grit better matches what failed during the cycle. Sketch meaning-29-3 pairs lint traps with stacking kit as alternate explanations that still honor the published family text. Reminder meaning-29-4: power quality can mimic control faults; lint accumulation can mimic plumbing faults — test, don’t guess. Workbook line meaning-29-5 asks whether iron staining changed recently and whether sabbath settings was already ruled out. Entry meaning-29-6 weighs sensor contamination before hot share valves when deciding whether owner checks are enough. For packet meaning-29-7, technicians appreciate notes about cycle timing; homeowners can also mention shipping bolts. Case meaning-29-8 separates municipal supply from connector oxidation so the visit starts with clearer hypotheses. Log meaning-29-9 should capture self clean residue. If absent, fall back to observing pet access only. Priority stack meaning-29-10: resolve obvious load balance issues, then consider ice clogging only if symptoms remain.
