Cove Dishwasher Error Code 300114

Code 300114 is a Clean Filter message indicating the sump filtration system needs maintenance. It is not an error or mechanical failure. The dishwasher is notifying you that the sump screen and removable filter have accumulated enough debris to require cleaning. Addressing it promptly helps maintain wash performance and protects the pump and hydraulic components.

You can continue using the dishwasher for a short period, but cleaning should not be delayed. A clogged filter restricts water circulation, which reduces cleaning performance and puts additional strain on the recirculation pump. Prolonged operation with a heavily blocked filter increases the risk of pump wear or more serious faults.

In most cases, there is no cost involved because the fix is simply cleaning the filter, which requires no parts or tools beyond what is in your home. If the filter assembly is cracked or damaged and needs replacement, part costs typically range from a modest amount depending on the component, plus any applicable labor if you choose professional service. Routine filter cleaning on a regular schedule helps avoid any repair costs entirely.

Remove and clean both the sump screen and the removable filter at the bottom of the dishwasher tub. Use caution when removing debris to avoid pushing particles into the pump or wash arm passages. Rinse the filter components thoroughly and reinstall them securely before running the machine again. The notification should clear once the filter system is clean and the machine resumes normal operation.

A simple reset will not permanently clear code 300114 because it is tied to the condition of the filter, not a control board error. The correct resolution is to physically clean the sump screen and removable filter. If the code reappears quickly after cleaning, check whether the filter is damaged or whether load soil levels are unusually high.
