Cove dishwashers are engineered for quiet, reliable performance, but when a unit refuses to begin a cycle, the cause can range from a minor power glitch to an issue requiring expert service. Even the most durable luxury appliances eventually need attention.

The list below details the five most common reasons a Cove dishwasher will not start, along with advice on when to call a trusted service provider, such as Wilshire, for professional repair.

1. The Door Latch Has Not Engaged

The first check should always be the door. Cove units are designed with a safety mechanism, preventing the machine from running unless the door is fully closed and securely latched. Over time, the latch mechanism might shift, or a simple obstruction can block a tight seal.

Inspect the interior of the machine. Make sure large items, like baking sheets or extended utensil handles, are not pressing against the door. Examine the latch itself for visible damage or any sign of misalignment. If the door seems to close completely, yet the dishwasher remains unresponsive, it is time to schedule a service appointment.

2. A Disruption in the Power Supply

A loss of power is another frequent cause when a unit fails to start. A tripped circuit breaker or a plug that has worked loose can cut power without warning. This is common after moving the appliance slightly or following an electrical fluctuation in the home.

First, confirm the dishwasher cord is firmly seated in the outlet. Then, inspect the home’s main breaker box to see if the dedicated circuit has tripped. If the connection appears normal but the control panel remains dark or unresponsive, contacting a professional for service is the correct next step.

3. The Delay Start Feature is Active

Many Cove dishwashers come equipped with a Delay Start option, which is useful for scheduling a cycle for a later time. However, if activated unintentionally, the dishwasher will appear to be broken when it is simply waiting for its scheduled start time.

Look closely for a timer icon or a countdown on the display panel. The setting should be canceled before trying to start a new cycle immediately. If the control panel is frozen, or the cycle will not clear, a specialist needs to examine the appliance.

4. The Dishwasher is Not Receiving Water

A consistent water supply is essential for a Cove dishwasher to begin its cycle. If the main water valve is closed or the supply hose is kinked, the machine cannot fill. It will sit idle or attempt to drain, leading to a failure to start. This problem is often missed, especially following plumbing work or a new installation.

Confirm that the water valve, typically located beneath the sink, is completely open. Inspect the water hose behind the unit for any visible bends, crimps, or damage. If the dishwasher displays an error code on the control panel, or if it drains without ever filling, contact a professional service provider.

5. The Unit is Stuck in Showroom Mode

Cove appliances sometimes leave the factory or the showroom with the demonstration mode still enabled. This setting allows the unit to power on for display purposes but disables all actual washing functions. The machine appears fully powered but refuses to begin a cycle.

Refer to the user manual for instructions on how to exit showroom mode. This process usually involves holding a combination of specific buttons for a few seconds. If those steps do not resolve the issue, scheduling a repair is the best solution for returning the dishwasher to normal operation.

When to Bring in a Trained Technician

If the obvious fixes have been exhausted and the Cove dishwasher still will not start, it is likely time to involve a trained professional.

The basics do not solve the problem.

When simple checks fail, it usually indicates an internal, technical issue that requires expert attention, particularly with high-end brands like Cove.

Repeated error codes or flashing lights appear.

Blinking indicators or unfamiliar error codes often signal a problem ranging from a sensor failure to a software glitch. A technician can quickly read the diagnostics and complete the necessary repair.

An electrical or control board failure is suspected.

If the control panel lights up but is unresponsive, or if the unit is completely dark, the fault may lie in the complex circuitry. These repairs should be handled exclusively by certified professionals.

The unit is a built-in or panel-ready model.

Built-in Cove dishwashers are highly integrated with custom cabinetry. Attempting a repair without proper training risks both cosmetic and functional damage. It is always safer to schedule service with a qualified expert.
