The computer expects the probe resistance to change with oil temperature. A short makes the reading impossible, and the display shows SYSTEM and FAILURE in turn. Pitco's service steps are to test the probe with an ohmmeter and check the wires and connectors between the probe and the controller for a short. Pitco commercial appliance display · also shown as SYSTEM What to do when SYSTEM FAILURE shows on the commercial appliance ### Kind of code Sensors 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. ### Usually leads to Commercial controls and board repair Controllers, touch panels, relays, contactors and interlocks tested, and replaced only when the evidence says so. ### Shows up as Commercial 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. ### Make Pitco A Pitco visit begins only once the vat is cool enough to drain, since nobody on the crew should be reaching near hot oil. ### Source Pitco Solstice and Solstice Supreme SG/SSH series gas fryer service manual (L22-345 R1) Pitco computer controls on Solstice and Solstice Supreme gas fryers (L22-345). The Digital Solid State Control reports the same shorted probe as Prob HI, and the SELV manual lists a shorted temperature probe in its controller table. ## Before you book, in this order. Each step comes from Pitco's own guidance for SYSTEM FAILURE on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Switch the fryer off and move frying to another tank or fryer. 02 Check that nothing has been jammed against the probe or its wiring during cleaning, without removing any covers. 03 Have the probe and harness tested on a visit and the shorted part replaced. ### Still there? It usually turns into [commercial controls and board repair](https://commercialappliancerepair.center/services/commercial-controls-and-board-repair/). Book with the code and the model number. ### What not to do Despite the broad name, SYSTEM FAILURE on these fryers points at the probe circuit, not at the whole control. It is the shorted partner of PROBE OPEN, which is the open circuit. ## What you may notice with it. The commercial appliance problems SYSTEM FAILURE tends to arrive with.

Switch the fryer off and move frying to another tank or fryer. If it comes back, it needs a visit. ### Does SYSTEM FAILURE mean my Pitco computer is dead? Usually not. Pitco's own service steps for this message test the temperature probe and its wiring for a short before looking at the computer. ### Can I reset SYSTEM FAILURE on a Pitco by turning it off? The message may clear for a moment, but a shorted probe will bring it back as soon as the control reads it again. ### Is SYSTEM FAILURE on a Pitco dangerous? The control stops trusting its temperature reading, so the tank should not be used. Book a visit rather than running it with a thermometer. --- **[Read on the site: Pitco SYSTEM FAILURE: the temperature probe circuit is shorted](https://commercialappliancerepair.center/error-codes/pitco-system-failure/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
