Thanks George. All outside my area of competence. Would you go for an official LG technician to fix (if they exist) or any other suggestions about making sure any technician would be up to the job?
LG use a third party company for their repairs.. You could follow this website link to book a repair... However, If you can let me know your postcode David, I can let you know of some independent engineers most local to you who can test and repair LG appliances.
Please rate the assistance given by me today
George - EX1 2BG. Would prefer a good independent any day.
PS - it's definitely button-related. On the 25th bang (to the side of the appliance not front or top) it started. Then I tried to pause it - but it won't pause. So not apparently related to door-locking mechanism.
