What E1
actually means.
On U-Line's clear ice and craft ice models, E1 in the service error log means thermistor 1 reads as an open circuit. U-Line's list names the sensor only by number; the manual's thermistor section describes a sensor on the right side wall of the ice bin that controls the ice level.

What to do when E1 shows on the ice makerKind of codeTemperature sensors
The control lost track of how cold the ice mold or the ice compartment is, because a thermistor reads nonsense or its wire lost contact. Without that reading the ice maker cannot tell when a batch is frozen, so it stops or harvests at the wrong time. Frost packed around the sensor and a loose plug are checked before the sensor itself is changed.
Usually leads toIce maker control and sensor repair
The control board, the thermistors, the bin sensor and the wiring that decide when an ice maker fills, freezes and stops, tested and repaired when a light flashes, a code shows, a breaker trips or the ice never stops coming.
Shows up asIce Maker Making Too Much Ice
The ice maker making too much ice overfills the bin, pushes cubes into the chute, jams the door ice compartment or keeps the freezer drawer from closing.

U-Line 15-inch clear ice (HCL, OCL, ACP) and craft ice (RCC) models. U-Line says all errors are logged in memory, but only the door error shows on the display with a tone; the others are read from the error log in service mode.
Before you book,
in this order.
Each step comes from U-Line's own guidance for E1 on its ice makers. Follow it to the end: the last card says whether this is a visit.
Note the code and the model number from the plate inside the unit.
Switch the unit off and back on once to see whether ice making resumes normally.
Book a visit so the thermistor and its connector can be measured.
Still there?
It usually turns into ice maker control and sensor repair. Book with the code and the model number.
What not to do
E1 is not a water or drain problem. It concerns a temperature sensor circuit, and the owner will not see it on the display unless it is read from the log.

Questions
about E1.
Can I clear E1 myself?
How do I see E1 on a U-Line ice maker if the display does not show it?
What does an open thermistor do to a U-Line clear ice maker?
Can a dirty connector cause E1 on a U-Line?

Still showing E1?
Book with the code or the blink pattern written exactly as the ice maker shows it, the full model number, and whether there is any water on the floor — when there is a code, that is where the diagnosis starts.
