Bad Experience with DEFY Dishwasher

We bought the DEFY 12 Place S/Steel Dishwasher (DDW 181) on 16/12/2017. We are using the machine once a week. Since we bought this Dishwasher it only gave problems.

1. The top drawer that takes the glasses, struggles heavy to close, you need to force it to go till the back, this is very frustrating. 2. The dishes never comes out dry, we need to dry everything by hand when unpacking the dishes after a cleaning cycle. 3. The dishes does not come out clean, there is still food and stains on the glasses, dishes and cutlery after a wash. Yes we do pack them with spaces between everything and we do use the hottest cycle. 4. It sometimes leaves white stain marks all over all the dishes, then we need to begin a new cycle all over again. 5. Sometimes all the dishes comes out like it's got an oil coating all over it.

Please get back to me regarding this matter asap.
