Hi, My inlaws have a Fisher & Paykel dishwasher 920 which is starting to leak and I would like to replace the seal for them. I have found the correct seal to replace the old one however I'm unsure if I will be able to install it correctly myself. Apparently all I need to do is "undo the screws holding on the slips which hold in the seal for this particular model"Is it really that easy? I've searched videos on youtube but the videos seems to be of other models and the seals just push on and pull off. Cheers
