Seeing an unfamiliar error code on your Cove dishwasher can make it difficult to know what went wrong. Fortunately, Cove dishwasher error codes are designed to identify the system experiencing a problem, which can help narrow down the cause.
Depending on the code, the dishwasher may be experiencing a drainage problem, water supply issue, wash pump drive system error, or detected leak. Some problems may interrupt a cycle completely, while others can affect normal dishwasher performance.
Understanding Common Cove Dishwasher Error Codes
Cove dishwasher error codes provide diagnostic information about specific systems within the appliance. However, an error code does not necessarily identify the exact component responsible for the problem.
That distinction is important. Two dishwashers displaying the same code may require different repairs depending on what caused the fault. A professional diagnosis can identify the underlying issue rather than relying on the code alone.
Here are several Cove dishwasher error codes you may encounter.
Error Code 800186 (MOT4): Poor Draining
Cove dishwasher error code 800186, also identified as MOT4, indicates that the dishwasher is experiencing insufficient or poor draining.
A dishwasher relies on its drainage system to remove used wash water during and after a cycle. When that process is interrupted, water may remain in the dishwasher and normal operation can be affected.
Drainage problems can have more than one possible cause, and the error code itself does not confirm which component is responsible. While keeping the dishwasher’s accessible filter clean according to Cove’s maintenance recommendations can help support normal performance, a recurring MOT4 error deserves further attention.
If error code 800186 continues to appear, professional service can determine what is preventing the dishwasher from draining correctly and identify the appropriate repair.
Error Code 050117: Wash Pump Drive System Under Voltage
Cove identifies error code 050117 as a wash pump drive system under-voltage Vbus error. Cove notes that fluctuations in residential AC power can cause this error.
The wash pump plays an important role in dishwasher operation by circulating water during the wash cycle. When the drive system detects an improper voltage condition, the dishwasher may not be able to operate as intended.
Because this code specifically involves voltage, diagnosing the underlying problem requires more than routine dishwasher maintenance. Homeowners should not attempt to access wiring, electrical connections, or internal dishwasher components to investigate the error.
If error code 050117 persists, a qualified appliance technician can diagnose the voltage-related condition and determine what service is needed.
Error Code 050113: Wash Pump Drive System Open Phase Error
Cove dishwasher error code 050113 is identified as a wash pump drive system MOT1 open phase error.
Because the wash pump is responsible for circulating water throughout the dishwasher, the drive system must operate correctly for the dishwasher to complete its normal washing functions. An open phase error indicates a problem within this system that requires further diagnosis.
The error code does not, by itself, confirm which component has failed. Attempting to access or disassemble the wash pump assembly is also not recommended.
When error code 050113 appears, or returns, professional diagnosis is the appropriate next step. A technician can evaluate the wash pump drive system and determine which repair is necessary.
Error Code 050118: Wash Pump Drive System Over Voltage
Error code 050118 indicates a wash pump drive system over-voltage Vbus error, according to Cove.
This error is essentially the opposite voltage condition of error code 050117. Instead of detecting insufficient voltage, the dishwasher has detected an over-voltage condition involving the wash pump drive system.
Since voltage-related faults involve the dishwasher’s electrical operation, they should not be diagnosed by accessing internal electrical components at home. The code also should not be used to assume that a particular part has failed without proper testing.
If error code 050118 continues to appear, schedule professional dishwasher service. A technician can properly diagnose the condition and determine what is causing the over-voltage error.
Error Code 560187 (FE1): No Water Supply to Dishwasher
Cove dishwasher error code 560187, also known as FE1, indicates no water supply to the product.
Your dishwasher needs an adequate water supply to fill and complete its wash cycles. If the appliance cannot detect the expected water supply, it may display this error rather than continuing normal operation.
For applicable Cove dishwasher models, manufacturer guidance includes making sure the home’s water supply to the dishwasher is open and that the supply line is not kinked. However, homeowners should not pull the dishwasher out or attempt to access internal components to investigate the problem.
If the dishwasher has an available water supply but continues to display error code 560187, the cause may require professional diagnosis. A technician can evaluate the dishwasher’s water inlet system and related components to determine why the appliance is not receiving water as expected.
Error Code 300137 (FLT1): Leak in Base Detected
Cove dishwasher error code 300137, also identified as FLT1, means the dishwasher has detected a leak in the base.
A leak warning should be taken seriously because water may be present inside an area of the dishwasher that is not readily accessible. You might notice moisture near the appliance, but the absence of visible water outside the dishwasher does not mean the error can be ignored.
Cove does not recommend that homeowners access the dishwasher base to diagnose this error. Moving or disassembling the dishwasher to search for the source can also introduce unnecessary safety risks.
If the FLT1 error appears, professional service is the appropriate response. A trained technician can access the necessary components, locate the source of the problem, and determine the repair needed to restore proper operation.
Why Does My Cove Dishwasher Error Code Keep Coming Back?
A recurring Cove dishwasher error code generally means the condition that triggered the code still needs attention.
Although an error code identifies the affected system, it does not always identify the exact failed component. For example, a drainage error tells a technician where to begin diagnosing the problem, but additional evaluation may still be necessary to determine why the dishwasher is not draining correctly.
This is also why replacing a part based solely on an error code is not recommended. Professional diagnosis helps identify the actual cause and reduces the risk of replacing components that are still functioning correctly.
When Should I Call for Cove Dishwasher Repair?
Professional service is especially important when a Cove dishwasher error code involves an electrical condition, internal wash pump system, leak, or recurring drainage or water supply problem.
It is also worth scheduling service when an error returns repeatedly or prevents the dishwasher from completing normal cycles. Continuing to operate an appliance with an unresolved problem may allow the underlying issue to worsen.
