Amana's ADB1400AGS is an entry-level dishwasher typically selected for affordability and basic, dependable cycles. Common failures are straightforward: door latches, drain pumps, inlet valves, and wash motors.
Because the unit's replacement cost is relatively low, the repair threshold is intentionally tight-repairs quickly become uneconomical if labor is high or multiple parts are needed. Repair is usually worthwhile for a single, clearly identified component failure when the dishwasher is not old and the tub and racks are in good condition.
Replacement becomes the better choice when wash performance declines due to motor and heating issues together, when leaks appear around seals or the pump, or when repeated service calls are needed. The price used represents a typical entry-level stainless-front market price for this model family.
