I had one of their washing machines. Purchased about 18 months ago. The dispenser drawer broke. I'm pretty sure it was bad out of the factory but it did last for this long, so I was happy to shell out for a new one.
Turns out they don't exist. LG have a website where you can search for the part. It's not in stock. They told me to fill out a form on a website they own, giving the part number. A third-party spare parts shop emailed me back saying they don't have the part in stock and that I should contact the manufacturer.
I found one that may or may not be the correct one and there's no way to know for sure before purchasing it. It costs almost £100 and takes 3 weeks to ship.
After days of this ordeal and laundry piling up, I decided to cut my losses and buy a Bosch. That one seems pretty great so far.
