Hi, I am trying to replace the hinge on a Siemens Integrated Dishwasher and I've got as far as needing to remove the side panels to get at the hinges. These look like they simply clip on and I have released them at the back of the machine. However, they don't seem to want to come off at the front. Is there something else that needs to be removed first? There are various parts that the side panels seem to sit on/clip to around each side but it's not clear whether these need to be removed as well. The model number is SN658D00MG/01.
