Whirlpool Dishwasher
Customer complaint: Not cleaning. Initial visit (Oct 21) — Tim B: Reported concern The customer reports that the dishwasher is displaying a drain error code during operation. Wastewater discharged into the sink drain is backing up and flowing back toward the appliance. Assessment The appliance is attempting to drain, but a backup within the household sink plumbing is preventing proper wastewater evacuation. This flow restriction forces effluent back into the system, causing the dishwasher to detect a drain fault and trigger an error. Next steps As the issue stems from the household plumbing rather than an internal appliance failure, the work order is being transferred to a plumber to inspect and clear the house drain lines.
