What E100
actually means.
The CTP keeps preventive maintenance timers for descaling, the water filter, cleaning, the ventless hood filter and the door gasket. E100 is called out when one expires without action. The manual asks you to open the maintenance reminder screen, do the item and reset it.

What to do when E100 shows on the commercial applianceKind of codeMode, not a failure
Nothing on the unit has broken; the controller is reporting a state it chose or one somebody set. A defrost pauses cooling for a scheduled melt and shows a warmer air reading for a while, a combi asks for a delime or runs its clean cycle and locks the door until it ends, a dish machine or a laundry machine sits in energy save between busy periods, and a door-open reminder beeps after a long delivery. No part is needed: letting the cycle finish, or the key sequence in the manual, brings the unit back.

An Alto-Shaam call is usually booked for the hours between the last plate and the prep crew, so the cabinet can cool and the tech can open it without holding up service.

Before you book,
in this order.
Each step comes from Alto-Shaam's own guidance for E100 on its commercial appliances. Follow it to the end: the last card says whether this is a visit.
Open the maintenance reminder screen to see which item has timed out.
Do that task, such as descaling or changing the water filter, and reset its timer.
Book a visit if the item is one you do not handle in house, such as a worn door gasket.
Cleared?
The code is gone from the controller, the box pulls down to its set point and holds it, the vat or the cavity reaches temperature and recovers on schedule, the rinse hits its heat and the drum finishes its spin, all without a new part. If the same code comes back within a week, or during the next busy shift, mention it when you book.
What not to do
E100 does not report a failure; the oven is asking for routine care. The maintenance codes 1001 to 1005 on the same screen name which task is due.

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.
