Dacor Range, Oven, Cooktop Error Code L5

Despite the appliance category listing, the L5 code is specifically associated with Dacor Third Generation dishwashers. It means the dishwasher has detected water flowing through the inlet valve when that valve should be fully closed and deactivated. The appliance triggers this code to alert you to a leaking or stuck-open inlet valve condition. Diagnosis should start by checking the inlet valve and flow meter for the source of the unintended water intake.

Yes, the L5 condition should be addressed promptly. A leaking inlet valve allows uncontrolled water to enter the dishwasher even when it is not running, which can lead to water accumulation, overflow, or damage to the unit and surrounding cabinetry. The dishwasher's control system triggers this fault precisely to warn you before a more serious flooding situation develops. Do not ignore this code or attempt to run the appliance repeatedly without resolving the underlying valve issue.

Repair costs vary depending on which component has failed. A replacement inlet valve typically runs in the range of $30 to $90 for the part alone, while a flow meter can range from $25 to $70. If you hire a technician, labor charges will add to those figures and total repair costs commonly fall between $100 and $300 depending on your area and the extent of the fault. Cleaning debris from an existing valve that has not mechanically failed would cost only the time required to do the work.

Some causes of L5 are accessible to a knowledgeable DIYer. You can inspect the inlet valve screen and seat for debris or mineral buildup and clean them without special tools. However, if the inlet valve diaphragm has failed or the flow meter is defective, replacing those components requires shutting off the water supply, disconnecting plumbing fittings, and working with the electrical harness. If you are not comfortable with those tasks, a qualified appliance technician should perform the repair.

A reset may temporarily clear the L5 code from the display, but it will not fix the underlying problem. If the inlet valve is still leaking when de-energized, the control board will detect water flow again during the next cycle and the code will return. The fault must be corrected by repairing or replacing the faulty inlet valve or flow meter before the code will stay cleared permanently.
