We have two Siemens fridges and a Siemens freezer, all integrated. Approx 3 years old, lightly used. The door panels on all three have gone out of alignment and now foul the cabinets when opened. It’s been suggested that this is likely to be hinge problems, despite the relative newness. Realignment doesn’t look a diy job for the inexperienced. Can’t see any identification on the actual hinges. Will buy new hinges if necessary but total cost is £250+ so want to be sure this is necessary. I’m not sure how to proceed, any suggestions please?
