What E2
actually means.
Humidified Flav-R-Savor cabinets heat a water reservoir to add moisture, and a separate sensor watches that side. E2 appears on the cabinet temperature display when that humidity sensor malfunctions. The cabinet may still hold heat, but moisture control is gone, so food can dry out or the water heater can run without proper supervision.

What to do when E2 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.

Before you book,
in this order.
Each step comes from Hatco's own guidance for E2 on its commercial appliances. Follow it to the end: the last card says whether this is a visit.
Check held items for drying and move sensitive food such as breads or proteins to another unit if needed.
Look at the water reservoir and keep it filled as normal while you arrange service.
Book a visit; the humidity sensor and its connection are not owner parts.
Still there?
It usually turns into commercial controls and board repair. Book with the code and the model number.
What not to do
E2 is not an empty reservoir signal; the reservoir having no water is its own condition in the troubleshooting table. It is also different from E1, which covers the air sensor.

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.
