Cove Dishwasher Error Code 050116

Error code 050116 indicates an overload error on MOT1, the main wash pump motor. The dishwasher's drive system has detected that the motor is operating under excessive load and has shut it down as a protective measure. This is most commonly caused by a physical blockage inside the wash pump, though motor wear or a control board fault can also be responsible.

A reset may temporarily clear the error code, but if the underlying cause is still present, the code will return as soon as the dishwasher attempts to run the wash pump again. Always address the root cause first. A reset alone is not a repair and should only be used to confirm whether the issue has been resolved after performing diagnostics.

If the cause is simply a blockage, there may be no parts cost at all, just the time to clear the obstruction. If the wash pump motor needs replacement, parts and labor costs typically range from $150 to $400 depending on the component and service rates in your area. A motor control board replacement can push costs higher, generally in the $200 to $500 range including labor.

Start by removing the lower spray arm and filter assembly to inspect the wash pump for any foreign objects or debris lodged against the impeller. Clear any blockages you find, clean the filter thoroughly, and run the dishwasher again. If the error returns after clearing any obstruction, the pump motor or control board may need professional evaluation and possible replacement.

No, you should not attempt to run the dishwasher while this error is active. The wash pump motor is in an overload condition, and continued operation could cause permanent motor damage or create an electrical hazard. Resolve the fault before resuming normal use.
