# Monogram dishwasher: Cup Open is a reminder to latch the detergent cup

### What the appliance is actually doing

The detergent cup has not been closed. It is a reminder to add detergent and latch the cup, not a failure. On a fully integrated machine this is displayed on the TOP EDGE of the door, which is only visible when the door is open. Most owners have never seen it.

### Which machines this one applies to

Monogram fully integrated dishwashers. Monogram says plainly on their own range and oven table that they cannot list every code for every model past and present, so a code missing from their table is not proof that your appliance cannot raise it — and a code in it is not proof that yours can. The model number settles it.

### What to do about it

- Add detergent and latch the cup.
- The cycle will not start until you do — although pressing Start again without opening the door will override it.
- If it keeps appearing with the cup properly latched, the switch that senses it is the repair.

### Where this goes next

The job this usually becomes is [dishwasher door latch repair](/services/dishwasher-door-latch-repair/), and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 614-3572](tel:+13056143572) and describe what the display is doing before booking anything.
