Hello Everybody, greetings from Poland.

I would like to ask You for help. I have problem with my coffee machine WMF 1200 S.
First there was problem with error 187, 188 and 189. I have changed steam sensor for termistor 10kOhm and this is ok.
But, actually when a turn on the machine, first is heating espresso boiler and than machine starts to heat steam boiler.
There is some kind of problem with steam boiler. Because machine is heating steam bojler continuously, again and again.
Next is too much of steam in boiler and steam erupts from boiler. ?.

Can somebody help me. ? Thank You
