A locked Cove dishwasher door is typically caused by the child lock being engaged, a cycle in progress, a door latch needing manual reset, or a power interruption preventing the electronic release most cases are quick DIY fixes without tools.
Cove dishwashers (luxury line from Sub‑Zero/Wolf) prioritize safety features, so the door stays secured until conditions are met.
Child lock (most common cause)
Cove’s child lock prevents accidental operation and locks the controls/door.
Activate/deactivate:
- Touch and hold Heavy button for 10 seconds.
- Display shows “Child Lock: On” / “Locked” when active.
- Repeat to turn off (“Child Lock: Off”).
Lock persists through power outages. Cannot use with Sabbath mode.

Cycle not finished or paused
Door locks during operation to prevent spills; won’t unlock until cycle ends or properly paused.
Fix:
- Wait for cycle completion (display “Clean” or time 0:00).
- If paused mid‑cycle, press Start/Pause to resume or cancel.
- Cancel: Hold Start/Pause 3–5 sec until drain starts.
Door releases ~30–60 sec after drain completes.
Door latch stuck (manual reset)
Latch mechanism can stick from debris, misalignment, or power glitch.
Reset steps:
- Turn off power (unplug/breaker).
- Remove toe kick/front panel (screws/clips).
- Locate latch assembly (behind inner door or base).
- Insert screwdriver into blue circle/reset point; push spring plate forward to release latch.
- Reassemble panel; restore power.
Post‑serial 20007530 units have reset label on panel.
Power or electronic lock issues
Power loss mid‑cycle locks door electronically.
Fix:
- Confirm power (outlet, breaker).
- Unplug 10 min (hard reset).
- Try child lock toggle after repowering.
If latch won’t budge, door spring may be broken (pro replacement).
