# Monogram dishwasher error code C4

### What C4 means, in the maker’s own words

The machine filled twice after a power failure — a stuck or failed float switch, or a clogged drain or sump. It is the code that most often follows a summer storm in South Florida. 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

- Touch Start, then Cancel/Reset.
- Tap on the float cover — the plastic upside-down cup in the front left corner of the tub floor — to free a float that has stuck.
- Check the sump area and the filter for anything holding water in the machine.
- If it repeats, the float switch is tested rather than tapped.

### Where this goes next

The job this usually becomes is [dishwasher drain repair](/services/dishwasher-drain-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.
