Whirlpool Dishwasher Error Code 8-3 (stuck on)

The 8-3 error code means the dishwasher's drain motor is stuck in the on position due to a faulty drain motor drive circuit on the control board. The control board is continuously sending power to the drain motor when it should not be. In some cases, a shorted or overheated drain motor may have caused or contributed to the control board circuit failure. Both the control board and the drain motor should be inspected before completing the repair.

Resetting the dishwasher will not permanently clear the 8-3 code because the fault is caused by a hardware failure in the control board's drain motor drive circuit. The code will return as soon as the appliance attempts to run a cycle. A proper repair requires replacing the faulty control board and addressing any drain motor issues found during inspection.

Repair costs depend on which components need replacement. A control board is typically the main part involved, and control boards for Whirlpool dishwashers generally range from $100 to $250 for the part alone. If the drain motor also requires replacement, expect to add $40 to $120 for that component. Professional labor costs vary by region but commonly fall in the $100 to $200 range for this type of repair.

Technicians and experienced DIYers can address this fault by first disconnecting power to the dishwasher, then inspecting the drain motor and wiring connections for signs of overheating or shorting. If the motor and wiring look intact, the control board requires replacement. If burn marks or melted wiring are found at the motor, both the motor and the control board should be replaced to prevent repeat failure.

It is not recommended to continue operating the dishwasher with an active 8-3 fault. A drain motor stuck in the on state can cause the motor to overheat, and if a short circuit is present in the drain motor or wiring, continued operation could worsen damage to the control board or create a fire risk. Disconnect power until the repair is completed.
