Dacor Range, Oven, Cooktop Error Code L2

Despite being associated with Dacor range, oven, and cooktop product lines in some databases, the L2 code in this context actually applies to Dacor third-generation dishwashers. It indicates an overfill condition, meaning the dishwasher's control system has detected water inside the tub at an unsafe level, either through the pressure sensor or the float switch activation. The machine halts operation automatically to prevent a potential overflow.

No, you should not run the dishwasher while the L2 code is active. The code indicates the machine has already detected a potentially dangerous water level, and continuing to operate it could result in water overflowing onto your floor or into surrounding cabinetry. Leave the dishwasher off until the underlying cause has been diagnosed and corrected.

Repair costs vary depending on which component is at fault. Clearing a blocked drain hose or cleaning the pump filter is generally low cost, often between $0 and $100 if done as a DIY repair or a basic service call. Replacing an inlet valve or flow meter typically falls in the $75 to $250 range for parts and labor combined. A faulty pressure sensor or control board issue can push costs higher, potentially into the $200 to $500 range depending on parts availability and labor rates in your area.

Start by checking the drain pump and drain hose for blockages that may have left standing water in the tub from the previous cycle. Next, inspect the float switch to make sure it is not stuck in the raised position due to debris or scale. If those components check out, test the inlet valve for proper shutoff, examine the flow meter, and verify all wiring connections to the pressure sensor and float assembly are secure and free of corrosion.

A power reset may temporarily clear the L2 code, but if the underlying problem is not fixed, the code will return as soon as the dishwasher attempts its next fill cycle. If the drain is blocked or the inlet valve is faulty, the overfill condition will simply repeat. The code should be treated as a symptom of a real hardware problem that requires physical inspection and repair.
