Viking Dishwasher Error Code Both flash

The Both flash error means the dishwasher has detected water in the base pan located underneath the appliance. A moisture sensor in the base pan monitors for water accumulation and shuts the machine down when it detects a problem. This is a protective function designed to prevent floor damage and electrical hazards. The sensor circuit should measure approximately 175K ohms when the pan is dry and the system is functioning correctly.

No, you should not continue running the dishwasher while this error is active. Water in the base pan can come into contact with electrical components, creating a shock or fire hazard. The appliance should remain off until the leak is identified, the base pan is dried, and the fault is resolved.

Repair costs vary depending on the root cause of the leak. A door gasket replacement is typically the least expensive fix, generally falling in the range of $50 to $150 for parts and labor. Pump seal or pump assembly repairs can range from $150 to $400 or more depending on parts and labor rates in your area. Diagnosing the exact leak source before ordering parts will help avoid unnecessary expenses.

Start by removing the lower access panel and checking the base pan for standing water. If water is present, dry it out completely and then trace the source of the leak, checking the door gasket, pump seals, and hose connections. After repairing the leak and drying the pan, test the moisture sensor with a multimeter to confirm it reads near 175K ohms before running the machine again.

A reset alone will not permanently clear this error if water remains in the base pan or an active leak is still present. The moisture sensor will continue to detect the condition and re-trigger the fault. The underlying cause must be repaired and the base pan fully dried before the error will clear reliably.
