What Service 47.1
actually means.

During automatic cleaning the iCombi Pro pumps used water out of the cabinet. Service 47.1 reports that the waste water pump is defective. Rational still lists cooking as possible.

What to do when Service 47.1 shows on the commercial appliance

Kind of codeMotors and drives

Something that should turn is not turning, or not at the speed the controller expects. A washer-extractor's drive or its inverter may stop the spin when the load is out of balance or a bearing drags, a tumbler's belt may slip so the drum barely moves, a convection or combi fan may slow on worn bearings and bake unevenly, and a dish machine's wash pump may hum without spraying. Redistributing a load, confirming the door is latched and running the machine's own test cycle are fair; a drum, a belt or a motor is a visit, and nobody reaches into a drum that could still move.

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 47.1 on its commercial appliances. Follow it to the end: the last card says whether this is a visit.

01

Check the drain screen and outlet in the cabinet floor for food scraps, fat or foil that could block the flow.

02

Check beneath the oven for pooled water and keep staff off that spot until it is mopped dry.

03

Book a visit before the next automatic clean.

What not to do

Service 47.1 is not the circulating pump (Service 48.1) or the steam generator pump (Service 110). It does not stop cooking, but it will stop cleaning working properly.

Questions
about Service 47.1.

Can I clear Service 47.1 myself?
Check the drain screen and outlet in the cabinet floor for food scraps, fat or foil that could block the flow. If it comes back, it needs a visit.
Can I still cook on a Rational with Service 47.1?
Yes. Rational lists cooking as possible; the pump is needed for cleaning, so book the repair before the next clean.
Why is there water on the floor with Service 47.1 on my Rational?
If the waste water pump cannot move water out, it can collect where it should not. Keep people clear and dry the floor before anyone works near the oven.
Is Service 47.2 different from 47.1 on a Rational?
The manual gives both the same wording. The number helps the technician tell which pump step failed.

Back to your everyday

Still showing Service 47.1?

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.
