What E01
actually means.
Delfield's table names sensor 1 as the air sensor. It is the one the control relies on to decide when to cool, so with E01 showing the cabinet temperature is no longer properly controlled.

What to do when E01 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.

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.

For a Delfield station that runs warm by late lunch, we time the visit to a slow hour so the pans can come out and the rail can be tested empty.

It usually turns into commercial controls and board repair. Book with the code and the model number.
What not to do
E01 is not a warm alarm, but a warm or overly cold cabinet may follow. E02 is the coil sensor, which affects defrost more than the cabinet temperature.

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.
