Thanks Picasso, We have a combi. I had the main unit witched off for about 45 minutes this morning, when I switched it back on and turn the shower on again, it ran for a minute then stopped with the display saying WAIT then it went to SERVICE 13 after another minute the shower ran OK. also...

We are now getting SERVICE 11 error on our Grohthem Wireless Shower. When we use it the display says WAIT, it then runs for a minute or two then stops with the above error code. Can anyone help us. Many thanks.
