MIele dishwasher gurgling sound
I am new to this forum - I am replacing most of the kitchen appliances with Miele ones.
I bought a Miele G5815 SCi Topaz dishwasher which was installed by a Miele installer. The machine will make quite loud gurgling sounds, when it first starts and at other times.
I understand MIele dishwashers are quite (this model is rated Q4), but the gurgling sounds defeat what should be a quite dishwasher.
Is there anything wrong with this?
Please see the picture for the manner in which the drain was installed.
