What E10
actually means.
The ChefsCombi sorts its messages by color, and E10 is one of the information messages that do not stop a cook. It reports scale in the steam generator and asks for a descale as soon as possible. If the message stays after descaling, Vulcan asks for the service provider.

What to do when E10 shows on the commercial applianceKind of codeWater, fill and drain
Water is not arriving, not reaching its level, not heating or not leaving on time. A dish machine may be short of fill because a supply valve is half closed or its line strainer is clogged, it may drain slowly through a scrap basket full of debris, or its booster may be too scaled to heat the rinse; a combi's steam generator may be scaled or its water treatment exhausted; a washer-extractor may time out on a slow drain. Opening the supply valve, cleaning strainers with the unit off and checking the drain line are fair; a pump, a fill valve, a heater or a leak near wiring is a visit.

Before you book,
in this order.
Each step comes from Vulcan's own guidance for E10 on its commercial appliances. Follow it to the end: the last card says whether this is a visit.
Finish the current cook; the message does not stop it.
Run the descaling procedure from the ChefsCombi manual as soon as the oven is free.
Use only cleaning and descaling products the manual approves for this oven.
Book a visit if E10 stays after descaling, and ask about water treatment for the supply.
What not to do
E10 is not a failure of the steam generator itself; it is an early warning. It is also separate from E90 and E91, which report the steam generator failing to deliver during cooking or cleaning.

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.
