Does your machine have the Care control?

How much mineral build up in the steam generator?

How is the cooking center used? Hours per day?

The triple solenoid valve green coil fills the generator. As it fills, the CDS sensor monitors how much water goes into the generator. It's located just before the triple solenoid valve. As minerals build up the board will determine that. Service 11 is the CDS sensor I believe. But we'll wait for Ectofix to come in on this.

Serial number would be helpful as they have made a lot of changes over the years.

I see Service 11 as the subject line so I will go with that.

This error means when the steam generator is filling, it measured more water than steam generator can hold until the water level probe sensed the water.

In most cases, this means water is passing the venting valve at the same time steam generator is filling.

It can also mean intermittent water level sensing if you got a little bit of scale forming on the water level electrode.

As a more complex problem, it could mean either the reference volume of steam generator is incorrect or the CDS is not set for 1000 pulses/litre. This is less likely.
