Cove Dishwasher Repair

Cove dishwashers are designed to be the quietest and most adaptable appliances in the world, perfectly suited to Sub-Zero and Wolf kitchens. If your machine leaves spots on glassware, doesn’t drain properly, or makes unexpected noises, it needs specialised care. We troubleshoot their advanced filtration systems, circulation pumps, and spray arms to ensure your precious china and crystal are cleaned with the quietness and precision you expect.

Common Cove Dishwasher Issues

01: Water Inlet Fault. The unit isn’t filling with water. Fix: Check the home water supply valve. Ensure the inlet hose isn’t kinked and the inlet valve screen isn’t clogged with sediment.
02: Drain Fault. Water is remaining in the sump. Fix: Clean the fine and coarse filters at the bottom of the tub. Check the “air gap” on your sink or the drain hose for a clog (often a piece of plastic or a bone).
03: Wash Motor Fault. The main pump isn’t circulating water. Fix: Could be a piece of glass jamming the impeller. If clear, the motor or the start capacitor may have failed.
04: Diverter Fault. The valve that switches water between spray arms is stuck. Fix: Often caused by a foreign object falling into the sump. Requires a technician to clear or replace the diverter.
05: Heating Fault. Water is not reaching the set temperature. Fix: Check for a tripped circuit breaker. If the power is fine, the heating element or the control relay is likely faulty.
08: Temperature Sensor. The thermistor (NTC) is sending an invalid signal. Fix: The sensor or its wiring harness needs to be checked for continuity and replaced if defective.
20 / 30: Leak Detected. The leak protection system has sensed water in the base pan. Fix: Turn off the water supply immediately. Dry the base pan; if the code returns, you have an internal leak.

Specialized Cove Troubleshooting

1. The “Clean” Light is Flashing

If the “Clean” light flashes and the unit won’t start, it often indicates the door wasn’t latched properly or a cycle was interrupted.

The Fix: Open the door, press and hold CANCEL for 3 seconds to reset the board, then close the door firmly until you hear the latch click twice.

2. “Door” or “Lid” Message

Cove dishwashers have very sensitive door sensors to maintain their airtight seal.

The Fix: Check if a dish or a long utensil handle is preventing the door from closing flush. Even a 1mm gap will prevent the machine from starting.

3. Hard Reset (The Sub-Zero Secret)

Since Cove is part of the Sub-Zero family, the electronics are high-quality but can occasionally “lock up.”

The Fix: Turn off the dedicated circuit breaker in your home’s breaker panel for 60 seconds, then flip it back on. This forces a full reboot of the control module.

The OEM Advantage

Cove appliances are built with high-grade materials and complex sound-dampening insulation. We use only genuine OEM Cove parts for repairs. Generic components can compromise the machine’s near-silent operation and custom fit. We ensure every repair meets the exacting standards of the Sub-Zero / Wolf / Cove family.

We service all configurations of Cove dishwashers, including:

24″ Built-In Dishwashers: DW2450 Series
Panel-Ready & Stainless Steel: Custom cabinet-front and classic stainless finishes

Frequently Asked Questions: Cove Repair

Is there a fee for the service call?

We offer a $0 service fee with any completed repair. If you choose to proceed with the fix, the diagnostic fee is completely waived.

Do you use genuine Cove parts?

Yes. To ensure your appliance maintains its high standard of performance and to protect your warranty, we use exclusively genuine OEM (Original Equipment Manufacturer) parts. These components are specifically engineered to fit the unique dimensions and specifications of Cove’s appliance lines.

Do you provide a warranty on your work?

Yes. All our Cove repairs come with a comprehensive 90-day warranty on both parts and labor. We stand behind our quality so you can have peace of mind.

Is it worth repairing my Cove appliance or should I replace it?

Because Cove appliances are often integrated directly into your cabinetry, replacing them can be a complex and expensive process. Repairing is usually the most cost-effective and convenient option, as it preserves the seamless look of your kitchen without the need for custom carpentry or installation adjustments.
