# Rational Service 10: the steam generator's automatic control needs a technician

The steam generator is the boiler that makes fresh steam for steam and combination modes.

## What Service 10 actually means.

The steam generator is the boiler that makes fresh steam for steam and combination modes. Service 10 says the logic that runs it on its own is not behaving as expected. Rational marks this message as one where cooking can go on.

What to do when Service 10 shows on the commercial appliance

### Kind of code Water, 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 to Dish machine repair

Undercounter, door-type and conveyor dish machines: tank heaters, boosters, wash pumps, fill and drain valves.

### Shows up as Commercial Appliance Error Code on a Combi, Fryer, Dish Machine or Laundry Display

A commercial appliance error code appears as letters or numbers on a combi, fryer, reach-in controller, dish machine or laundry machine display, or as a flashing light or an alarm tone.

### Make Rational

A Rational visit is timed after the evening cleaning cycle, when the cabinet is cool and the display can be read without a load inside.

## Before you book, in this order.

Each step comes from Rational's own guidance for Service 10 on its commercial appliances. Follow it to the end: the last card says whether this is a visit.

01

Finish the batch in the oven; the table says cooking is still available with Service 10 on screen.

02

Swipe the message aside so it shrinks to a red symbol at the edge of the display, and keep an eye on steam-heavy recipes for weak results.

03

Note the serial number and software version shown in the message, then book a visit.

### Still there?

It usually turns into [dish machine repair](https://commercialappliancerepair.center/services/dish-machine-repair/). Book with the code and the model number.

### What not to do

Service 10 is not the scale warning for the steam nozzle, which has its own number (Service 41). It also does not mean the oven has lost its water feed; that is reported under the water supply numbers in the 42 range.

## What you may notice with it.

## Questions about Service 10.

### Can I clear Service 10 myself?

Finish the batch in the oven; the table says cooking is still available with Service 10 on screen. If it comes back, it needs a visit.

### Can I keep cooking on a Rational iCombi Pro with Service 10?

Yes. Rational's own table marks cooking as possible with this message. Plan your steam-heavy items with a little extra checking until the steam generator has had its service check.

### What does SC stand for on a Rational Service 10 message?

It is the steam generator, the boiler inside the iCombi Pro that produces steam for moist and combination cooking. Service 10 concerns the automatic control of that part.

### Will Service 10 clear itself on a Rational combi?

The manual does not describe a reset for it; it asks you to contact a service partner for every error message. If it keeps returning after a restart, book a visit and have the serial number ready.
