What 050187 means on a Cove dishwasher

Error code 050187 on a Cove dishwasher indicates a water flow problem, meaning the appliance is not detecting adequate water entering the wash tub during a fill cycle. The control board monitors incoming water flow and will trigger this fault when the expected volume or rate of water is not achieved within a set time window. This code points to the water supply system, including the inlet valve, supply line, and any associated flow sensors or pressure components that confirm water is entering the machine.

The most fundamental cause to rule out first is whether the household water supply valve behind or beneath the dishwasher is fully open. If water supply is confirmed, attention should shift to the water inlet valve itself, which is a solenoid-operated component that opens on command from the control board. A failed solenoid, clogged inlet screen, or restricted supply line can all prevent adequate water flow even when house pressure is present.

Additionally, low household water pressure can cause this error if pressure is insufficient to open the inlet valve fully or fill the tub at the required rate. Kinked or pinched supply hoses restrict flow without fully blocking it, producing the same result. In some cases, a faulty flow meter or pressure switch that monitors fill level may misreport conditions to the control board, triggering the fault even when water is physically present.

Common causes of 050187

  1. 01

    Water supply valve closed or partially closed

    Wiring / connection

    The shut-off valve supplying water to the dishwasher may be fully or partially closed, blocking flow before it even reaches the appliance. Locate the valve under the sink or behind the unit and confirm it is turned completely open.

  2. 02

    Clogged water inlet valve screen

    Wiring / connection

    The inlet valve has a small mesh screen at its supply connection that filters debris from the water supply. Sediment or mineral buildup can restrict or block this screen, reducing flow to the point that the control board logs a fault.

  3. 03

    Failed water inlet valve solenoid

    Part replacement

    The solenoid inside the inlet valve opens the valve when energized by the control board. If the solenoid has burned out or failed mechanically, the valve will not open and no water will enter the tub.

  4. 04

    Kinked or restricted supply hose

    Wiring / connection

    The braided supply hose connecting the household water line to the dishwasher inlet can become kinked, pinched behind the unit, or partially blocked by mineral deposits. Inspect the full length of the hose for kinks or visible damage.

  5. 05

    Faulty flow meter or pressure switch

    Part replacement

    A flow meter or water pressure switch reports fill status to the control board. If this component malfunctions or reads incorrectly, the board may log a flow fault even when water is entering the tub at a normal rate.

Frequently asked questions about 050187

What does 050187 mean on a Cove dishwasher?
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.
How do I fix error code 050187 on my Cove dishwasher?
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.
Is it safe to use my Cove dishwasher while error 050187 is active?
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.
How much does it cost to repair a Cove dishwasher showing error 050187?
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.
Will resetting my Cove dishwasher clear error code 050187?
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.
