# Monogram dishwasher error code 999

### What 999 means, in the maker’s own words

On machines with the Floor Protect with Alert feature, a possible leak has been detected and the machine will not start. On all other machines, the control needs to be reset. 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.

### Where this code actually appears

On the control panel, and usually with a sound. Monogram describes their refrigerator codes as flashing green on the display and typically accompanied by a beeping, and the range, microwave and dishwasher tables all describe codes you can read from the front of the appliance. That is the opposite of some makes, where the number is written into a hidden log and never shown — here, if something is wrong, the appliance generally tells you. Photograph what it says before cutting the power, because a reset erases it and the code is most of the diagnosis.

### 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

- Establish which machine you have — the two answers are completely different.
- With Floor Protect: contact service. The machine will not start and that is deliberate.
- Without it: reset the control at the breaker for about thirty seconds.
- Either way, look under the machine for water first.

### Where this goes next

The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), 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.
