The drain hose on our (very old) IKEA Renlig DWT160 dishwasher has sprung a leak and I need to replace it. How do I remove the drain hose from the back of the dishwasher? Do I have to undo some parts to release it from the inside or can I just plier or twist it out? I don’t want to try anything until I know for sure! We’ll be replacing it all next year but right now is just a bit too early. Thanks. PCN911989307/03
