What E57
actually means.
The CTP uses a separate valve for rinse water, watched by a flow switch. E57 is called out when that switch sees nothing for 60 seconds or more. A closed supply, low pressure, or a dirty or failed flow switch are the causes the manual lists.

What to do when E57 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.

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 E57 on its commercial appliances. Follow it to the end: the last card says whether this is a visit.
Check the water valve to the oven is fully open.
Confirm normal pressure at nearby sinks.
Book a visit if water is on and E57 returns; the flow switch may need cleaning or replacing.
What not to do
E57 is not the steam generator fill, which reports as E01 or E51. It is also different from E105, which is the general water pressure switch.

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.
