What we can confirm
Code PrS, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
PrS
The pressure sensor is sending an invalid signal to the control, and the machine either will not start or cancels the cycle. The manufacturer says this is most likely a harness or sensor issue. 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.

What else belongs to the dishwashers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

About Monogram dishwasher error code PrS
What PrS means, in the maker's own words
The pressure sensor is sending an invalid signal to the control, and the machine either will not start or cancels the cycle. The manufacturer says this is most likely a harness or sensor issue. 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
- Reset the control at the breaker for about thirty seconds — worth one attempt.
- This is a service call rather than an owner fix: the sensor and its harness are measured.
- In coastal air, connectors are as often the cause as the sensor itself.
Where this goes next
The job this usually becomes is 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 and describe what the display is doing before booking anything.
