What Prob
actually means.
The Digital Solid State Control has a short display, so it abbreviates. When it cannot see the probe at all, it shows Prob, and Pitco's service manual sends the technician to test the probe and then the wiring and connectors back to the control for continuity.

What to do when Prob shows on the commercial applianceKind of codeSensors and probes
A probe is handing the controller a reading it cannot trust, or none at all: a box or coil sensor torn loose from its clip, a fryer probe coated in carbon from oil left too long between filterings, a combi core probe with a kinked cable, or a connector gone green from steam and cleaning chemicals. The unit then runs on, stops, or shuts the heat or the cooling off to protect itself. Letting it cool and restarting it as the manual describes is fair; a probe that still reads wrong sits behind a panel, and that is a visit.

Controllers, touch panels, relays, contactors and interlocks tested, and replaced only when the evidence says so.
Shows up asCommercial Appliance Error Code on a Combi, Fryer, Dish Machine or Laundry Display
A commercial appliance error code appears as letters or numbers on a combi, fryer, reach-in controller, dish machine or laundry machine display, or as a flashing light or an alarm tone.

A Pitco visit begins only once the vat is cool enough to drain, since nobody on the crew should be reaching near hot oil.

Before you book,
in this order.
Each step comes from Pitco's own guidance for Prob on its commercial appliances. Follow it to the end: the last card says whether this is a visit.
Turn the control off and stop frying on that tank.
Write down when Prob first showed and whether it comes and goes, which helps find a loose connector.
Have the probe and its connections metered on a visit.
Still there?
It usually turns into commercial controls and board repair. Book with the code and the model number.
What not to do
Prob alone is the open probe; Prob followed by HI is the shorted probe. Neither is the same as HEAt FAIL, which is about the heat circuit rather than the temperature reading.

A booking with a code goes further when it has the code as shown, the model and serial from the data plate, and a word on whether the unit still holds temperature, heats, rinses or spins. With those three, the office can match the likely part to your unit the same day.
