Cove Dishwasher Error Code 300114

Error code 300114 on a Cove dishwasher is a maintenance notification, not a fault or failure code. It indicates that the sump filtration system has accumulated enough debris, grease, and food particulate that the filter assembly requires cleaning. The sump is the basin at the bottom of the dishwasher tub where water collects before being recirculated through the wash arms or drained. The filtration system typically consists of two components: a coarse sump screen that captures larger debris and a finer removable cylindrical filter that traps smaller particles. When these components become clogged, wash performance degrades and the machine triggers this notification.

The primary concern during filter service is preventing debris from entering the hydraulic system. Loose food particles, broken glass, or other material that bypasses the filter and enters the pump or wash arm passages can cause mechanical damage or blockages that result in more serious faults. The notification is designed to prompt cleaning before restriction becomes severe enough to affect pump performance or water circulation. Regular filter maintenance is the most effective way to prevent this code from appearing and to maintain optimal cleaning results.

Clearing this code requires physically cleaning both the sump screen and the removable filter, not simply resetting the control board. After cleaning, the machine should recognize that normal flow conditions are restored. If the notification returns very quickly after cleaning, it may indicate unusually heavy soil loads in regular use, or it could point to a separate issue affecting how the system monitors filter condition.
