Cove Dishwasher Repair
Cove is the dishwasher made by Sub-Zero Group, usually installed next to a Sub-Zero and a Wolf behind a matching custom panel. We repair panel-ready and stainless Cove dishwashers in place where we can, pull them out only when the repair needs it, and give you the price in writing before any work starts.

In short: a Cove that needs service usually will not drain or fill, stops with water in the base, leaves dishes dirty or wet, or has a door that drops open or will not stay closed. Many of these start outside the machine: a clogged filter, a drain or supply connection under the sink, detergent, or a custom panel that is heavier than the door springs were set for. We are an independent service, not affiliated with Sub-Zero Group.
The Cove dishwashers we service
Cove is the dishwasher brand of Sub-Zero Group, the company behind Sub-Zero refrigeration and Wolf cooking, and it is the newest of the three. That means most Coves in Orange County are still fairly young, and a problem on one is often about how it was installed rather than a worn part. Cove builds 24-inch built-in dishwashers in two styles:
- Panel-ready. The front takes a custom cabinet panel so the dishwasher disappears into the run of cabinets, with the controls on the top edge of the door, seen only when it is open.
- Stainless steel. A finished stainless front with a handle in the Sub-Zero and Wolf style.
Inside, both styles work the same way: a stainless tub, a filter and sump at the bottom, a circulation pump that drives the spray arms, a heater, a drain pump, a water inlet valve, and, as on most premium machines, a leak sensor in the base pan. The model and serial label is usually on the edge of the inner door or the tub frame, seen with the door open. A phone photo of it before the visit lets us check parts.

What goes wrong on a Cove, and why
Common Cove faults, and what to check before you call:
Not draining, or water left in the bottom
What it usually is: a filter packed with food and labels, a drain hose kinked behind the machine, a garbage disposal connection that is clogged or, on a new installation, still sealed by its knockout plug, or an air gap on the counter that has filled with debris. When all of those are clear, the drain pump itself or the check valve that stops dirty water flowing back is the cause. A cupful of water left in the sump after a cycle is normal on most dishwashers; a puddle over the filter is not.
What you can check: take out and rinse the filter, run the disposal for a few seconds, and clear the air gap cap if you have one.
What we do: follow the drain path from the sump to the sink, and test the pump. Our jobs Why Is My Asko Dishwasher Not Draining? (Irvine, October 2026) and Bosch Dishwasher E25 Error: The Drain Pump Fix (Newport Beach, September 2026) show the same diagnosis on other European-style built-ins.
Not filling, or filling slowly
What it usually is: the supply valve under the sink not fully open, a kinked supply line, a screen at the inlet valve clogged with hard-water scale, or the inlet valve itself. Orange County's hard water is hard on valves and screens.
What you can check: the shutoff under the sink, fully open, and that the hot water at the sink runs normally.
What we do: measure the flow at the machine, clean or replace the inlet valve, and check the water level the control reaches.
Stops with water in the base, or leaks onto the floor
What it usually is: premium dishwashers carry a leak sensor in the base pan. When water reaches it, the machine stops filling and pumps out to protect the floor. The water usually comes from a loose or cracked supply or drain connection, a worn door gasket, a sump or pump seal, or suds overflowing after hand dish soap went into the dispenser.
What you can check: look under the sink for drips, and think back to the detergent used. Do not tip the machine to drain the base; it can hide where the water came from.
What we do: find the source first, dry the base pan, replace the seal, gasket or hose, and run a full cycle with the kick plate off before we close up.
Door drops open, slams shut or will not latch
What it usually is: a panel-ready door is balanced by springs and cables set for the weight of the custom panel. A heavy wood or stone-look panel, or a panel added after the springs were set, wears the springs and cables and the door falls open. A broken spring or cable makes the door drop on one side. A latch that will not catch is usually a panel or door that is out of line with the tub, or a worn latch.
What you can check: open the door halfway and let go. It should stay roughly where you leave it.
What we do: weigh the door against the spring setting, replace springs and cables as a pair, and realign the door and panel so the latch catches cleanly and the panel lines up with the cabinets on either side.
Dishes not clean, cloudy or spotted
What it usually is: a clogged filter, spray arm holes blocked by seeds or glass, cold water at the start of the cycle, the wrong amount of detergent, or hard-water film. Less often the circulation pump is weak or the heater is not bringing the water up to temperature.
What you can check: clean the filter, rinse the spray arms, run the hot water at the sink before you start, and keep rinse aid topped up.
What we do: measure the water temperature through the cycle, test the circulation pump and the heater, and check the spray arms and their seals.
Dishes come out wet, or the water does not heat
What it usually is: an empty rinse aid dispenser is the most common cause of wet dishes. Plastics stay wet on any dishwasher. A failed heater or temperature sensor leaves the final rinse cool, so nothing dries, and the cycle may also run much longer than usual.
What you can check: rinse aid level, and whether the inside of the door is hot to the touch right after a cycle ends.
What we do: test the heater, its sensor and the control that drives them, and replace the failed part.
Controls dead or not responding
What it usually is: a control lock, which looks exactly like a dead panel, a tripped breaker or GFCI, a door switch that does not see the door closed, or a control board. On panel-ready models the controls on the top edge of the door can take steam when the door is opened mid-cycle.
What you can check: the breaker or GFCI, the control lock in the use and care guide, and that the door closes fully.
What we do: read any fault the control has stored, test the door switch and power supply, and replace the board only when the tests point to it.
How we repair a Cove in a finished kitchen
- In place where possible. The filter, spray arms, door springs, cables, latch, gasket and controls are reached from the front with the door open or the kick plate off.
- Out of the opening when needed. The drain pump, circulation pump, heater, base pan and hoses on some models need the dishwasher slid out. We protect the floor, support the panel so it does not scratch the neighboring cabinets, and disconnect water and power first.
- Mounting checked on the way back in. We reset the brackets to the counter or the cabinet sides, level the machine, and confirm the panel lines up and the door balances.
- Leak test before we leave. A full cycle with the kick plate off, connections dry, and the drain clear.
- Lead times up front. Common parts are on the van. Cove parts come from a distributor or Sub-Zero Group, usually in a few business days, and we say so before you decide.
What Cove repair costs
The $79 service call covers the trip and the diagnosis and is applied to the repair once you approve the written price. That price does not change after work starts. Typical ranges for premium dishwashers:
Luxury dishwasher repair (Miele, Cove, Thermador, Fisher & Paykel)
| Repair | Typical price, parts and labor |
|---|---|
| Drain pump | $350 to $600 |
| Water inlet valve or protected hose | $300 to $600 |

| DishDrawer motor or lid actuator | $400 to $800 |
| Electronic control board | $700 to $1,300 |
Typical Orange County ranges for parts and labor. The $79 service call is applied to any of them. Parts that ship from the manufacturer and older or discontinued models can run higher. You get the exact written price after the diagnosis and before any work starts.
Drain pumps, inlet valves and door springs are the common Cove repairs; control boards and circulation pumps cost more. Every table is on pricing.
How a Cove repair goes
- Call or book online. Max, who owns the business and still repairs appliances himself, answers. Tell us what the dishwasher does and whether it has a custom panel.
- Diagnosis and written price. A same-day or next-day visit Monday to Saturday when the schedule allows; the price and any parts lead time in writing.
- Repair. If the pump or base pan needs it, the machine comes out on padding on the same visit; ordered Cove parts go in on a return visit.
- Warranty. Parts and labor; the same fault back within 90 days means no service-call fee.

Cove dishwasher repair: questions
Is Cove made by Sub-Zero?
Yes. Cove is the dishwasher brand of Sub-Zero Group, the company that makes Sub-Zero and Wolf. We are an independent service, not affiliated with Sub-Zero Group, and if your Cove is still under its own warranty, contact Sub-Zero Group first.
Why does my Cove door fall open?
The door springs and cables are set for the weight of the panel. A heavy custom panel, or one added later, wears them out and the door drops. Springs and cables are replaced as a pair and set to the panel, which is a moderate repair.
Why is there water in the bottom of my Cove after a cycle?
A little water in the sump under the filter is normal. Water standing above the filter means a drain problem: the filter, the drain hose, the disposal or air gap, or the drain pump.
My Cove stopped mid-cycle with water in the base. Is it safe to run?
Not until the leak is found. The leak sensor stopped the machine on purpose. Close the water supply under the sink and call; tipping the machine to empty the base only hides where the water came from.
Why are my dishes cloudy?
In Orange County it is usually hard-water film: keep rinse aid topped up, run the hot water at the sink before starting, and use the detergent amount the guide gives. If dishes are also gritty, the filter or spray arms need cleaning, or the pump or heater needs testing.
Do you have to pull a Cove out to repair it?
Not for most repairs. Door, latch, controls, spray arms and filter are done from the front. Pumps, the heater and base-pan leaks often need it slid out; we protect the floor and the panel and tell you before we do it.
How much does a Cove dishwasher repair cost?
A door spring and cable set, an inlet valve or a drain pump is a moderate repair; a control board or a circulation pump is the larger one. The dishwasher table above gives typical ranges, and the written price comes before any work.
