Cove Dishwasher Error Code 050187

Error code 050187 on a Cove dishwasher signals a water flow problem, meaning the machine is not receiving adequate water during the fill phase of a cycle. The control board monitors incoming water and triggers this code when the expected flow is not detected. The first step is confirming the water supply valve is fully open before investigating internal components.

You should not run the dishwasher while this error is active. Without adequate water flow, the appliance cannot complete a proper wash cycle, and attempting to run it may result in incomplete cleaning or potential stress on the pump if it runs without sufficient water present. Resolve the water supply issue before starting another cycle.

A reset may temporarily clear the code from the display, but the error will return as soon as the dishwasher attempts to fill and encounters the same flow problem. The underlying cause, whether a closed valve, clogged screen, or failed component, must be corrected for the error to stay cleared. Do not rely on resetting alone as a fix.

Start by verifying the water supply valve is completely open and the supply hose has no kinks or restrictions. If water supply is confirmed, inspect the inlet valve screen for sediment buildup and clean it if clogged. If the screen is clear and supply pressure is adequate, the inlet valve solenoid or a flow-sensing component may need to be tested and replaced by a technician.

If the fix is simply opening a closed supply valve or straightening a kinked hose, there is no parts cost involved. Replacing a water inlet valve typically runs in the range of $50 to $150 for the part, plus labor if a technician is needed. Diagnosing and replacing a flow meter or pressure switch may cost somewhat more depending on the component and service rates in your area.
