Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries
Did you remove the transit bolts from the back and also the polystyrene packaging from underneath?
Just sending you up a copy of the instructions, not the items in the first couple of pages ~ you need to check that they have removed all the packaging from the appliance, there are bolts that pass through the back of the case and into the actual drum assembly inside and also a polystyrene block that sits under the motor to stop it getting bashed. If you open the door the drum inside should move freely back and forward, up and down if it does not then some part of the transit packaging be it bolts or packaging have not been removed ~~ http://www.electrolux-ui.com//DocumentDownLoad.aspx?DocURL=2013\192\981622EN.pdf
How are you getting on have you found anything?
