Viking Dishwasher 4-5 Error Code
A Viking dishwasher that logs 4-5 is asking for confirmation against the use & care guide. Simply Iconic can diagnose independently if the code returns.
Content status: Reviewed — wording follows cited Viking service literature; confirm decode on your exact model.
Plain-language Viking DW guidance — not a factory authorized procedure.
Viking dishwasher code 4-5 — safe owner checks first, then independent diagnosis if it returns.
Model compatibility: Viking reuses codes across series and model years, so 4-5 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
What this code means
Heat relay or drive fault — the control could not switch heating as expected. Reset the unit by pressing and holding the START button for four seconds, then try the cycle again. When the code returns after one reset, schedule Simply Iconic — not a factory independent service center.
