What Service 41
actually means.
Some iCombi Pro functions inject water through a nozzle into the cabinet to make steam directly. Service 41 reports scale on that nozzle or its pipe. Until it is cleared, the oven will not use steam injection.

What to do when Service 41 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.
Usually leads toDish machine repair
Undercounter, door-type and conveyor dish machines: tank heaters, boosters, wash pumps, fill and drain valves.

Before you book,
in this order.
Each step comes from Rational's own guidance for Service 41 on its commercial appliances. Follow it to the end: the last card says whether this is a visit.
Power the oven down and wait for the nozzle area to cool.
Descale the steam nozzle as the manual describes: remove it with a hex key, soak it in descaler with gloves and a mask on, rinse it, dry it and refit it.
If Service 41 comes back soon after descaling, book a visit and ask about your water hardness and filtering.
What not to do
Service 41 is not about the main steam generator; that has its own care status indicator and messages. It does not stop dry heat cooking, only the steam injection function.

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.
