The last few days, if I draw hot water (from the hot water wand, not the group head!) after my Giotto has been sitting for a while, there is a short burst of brownish (weak tea colored) water before clear hot water starts running.
The water from the steam wand is fine. If I draw water again a short time later its still fine. If I make a shot and then right away draw water it seems fine.
The machine is mainly used by people who drink espresso, so normally there will be multiple shots before someone uses the hot water.
Can anyone tell me whats going on? I replaced the control board myself recently, though not sure how rewiring could have caused this.
Any help very much appreciated...

to the steam, that will give you a good idea how bad it is. If its really offensive then youll need to do the job either yourself or through a service provider.
