Cove Dishwasher Filter Location: Where It Sits and How to Lift It Out

The Cove dishwasher filter sits in the sump at the bottom of the tub, directly beneath the lower spray arm, so the lower rack and spray arm come out first. To release the Cove filter, press it down lightly, turn it counterclockwise 1/8 turn and lift it straight up.

Cove prompts this job with a Clean filter message every 30 cycles. That Cove reminder counts cycles rather than measuring soil, so a busy Sonoma kitchen may need filter attention sooner.

Where exactly is the filter inside a Cove dishwasher?

Pull out the Cove lower rack and remove the lower spray arm from the tub floor. The filter assembly sits underneath, seated in the sump where wash water collects before the Cove pump recirculates or drains it.

A Cove dishwasher behind a custom wood panel, as in a restored home near the 1840s Mexican-era adobes around Sonoma Plaza, a National Historic Landmark, needs no panel removal; reaching the Cove filter happens inside the open tub.

How do you take the Cove filter out and put it back?

Step 1: Switch the Cove dishwasher off and let the tub cool if a cycle just ended.

Step 2: Press the Cove filter down lightly, rotate it counterclockwise 1/8 turn and lift it out.

Step 3: Rinse the Cove filter under warm running water with a soft brush; a wire brush can tear the fine mesh.

Step 4: Seat the Cove filter in the sump, press lightly and turn it clockwise until it locks without rocking, then refit the spray arm. An unlocked Cove filter lets debris slip toward the pump.

Why does the Clean filter message appear every 30 cycles?

Cove logs this reminder as code 30 01 14 for the sump filter, and the count runs on cycles alone, so it appears whether the filter is spotless or packed with seeds. If the Cove Clean Filter reminder stays on after a proper cleaning, switch the breaker off for 30 seconds and retest; a reminder that persists is a controls question for a technician.

What water hardness does to the Cove filter and tub

Hard water leaves mineral scale that binds with food film, so the Cove filter mesh clogs sooner and the tub turns chalky. Very soft water brings the opposite Cove problem: detergent that never fully rinses away.

Cove scales liquid, gel and powder detergent to hardness: fill the cup 1/3 for 0-3 gpg, 2/3 for 4-8 gpg and full for 9+ gpg. Overdosing a Cove in very soft water can cloud glassware.

On the Cove DW2451WS, test the supply with the supplied strip, then set Water Hardness in User Set Up by holding Options about 10 seconds; 0 is the default for 0-4 gpg, and 10 covers 25+ gpg.
