Cove Dishwasher Error Code 300137

Error code 300137 means the dishwasher has detected water in the base pan via the conductivity sensor, or has detected an overfill condition through the pressure sensor. Both situations indicate water is present where it should not be. The unit triggers this fault as a safety measure to prevent water damage. Shutting off the water supply and drying the base completely is the recommended first response.

No, you should not continue running the dishwasher while this error is active. The code indicates water has accumulated in the base of the unit, and running a cycle could worsen an existing leak or cause water damage to surrounding cabinetry and flooring. Turn off the water supply to the unit and leave it off until the error has been diagnosed and resolved.

Repair costs vary significantly depending on the root cause. If the fix is simply drying out the base, there is no parts cost involved. A door gasket replacement is generally a lower-cost repair, typically in the range of $20 to $80 for the part plus labor if a technician is needed. Pump seal or inlet valve repairs tend to cost more, with parts and labor potentially ranging from $100 to $300 or higher depending on the specific component and service rates in your area.

In some cases, yes. If the error was caused by residual moisture in the base pan rather than an active leak, thoroughly drying the base and conductivity sensor and then power-cycling the unit may clear the code without any parts or professional help. However, if the error returns after drying, an internal component such as a door gasket, hose, or pump seal is likely leaking and a technician should inspect the unit to identify and repair the source.

A power-cycle reset is actually part of the recommended diagnostic process, but it should only be done after the base pan and conductivity sensor have been fully dried. If there is still moisture present on the sensor, the error will return immediately after the reset. If an active internal leak is the cause, the error will also return quickly once water supply is restored, so a reset alone will not permanently clear the code in those cases.
