I have decided to use the washing machine 86305 WTE compared to WAQ284A1 - for the simple reason, because my Bedinungspanel WTE 86305 selbsterklaerender seemed. Have also the associated Bosch dryer WAQ acquired 28321, and the Stacking Kit WTZ 11310 Connection kit f. "Sensitive", which was recommended. (My bathroom is small, so everything on one another). The two guys from Hermes were great, 2nd floor without a lift! (Who gave me my fridge delivered (Samsung RL-34LW-Plus fridge-freezer - great refrigerator)!). Even the packaging material taken back, and advised me that I do not really braeuchte the Stacking Kit. Well, now I had ordered him and have also used it. Installation was easy, the appropriate drill bit was included, just four drill holes in the upper plate of the WaMa, screw and the dryer on top of it (weighs about 40kg), a friend helped.
