Sunbeam EM0440 GrindFresh Conical Burr Coffee Grinder, 25 Grind Settings, Direct to Handle Grinding, 250g Bean Hopper, for Espresso, Filter, Turkish Coffee and More, Grey/White

When I had initially tested the grinder, it worked well. After testing it I practised removing the BURR and replacing it, then I stored it in the caravan for using while travelling or when staying at our beach cottage.Upon grinding some beans a few weeks later, the grind was far too coarse even on the FINE setting. I had forgotten that it HAD worked properly earlier. I put up with it for a couple of brews before giving a poor review.I then remember that it HAD worked initially, so with the setting on FINE, I pressed and held down the UNLOCK button at the back of the grinder and rotated the setting past COARSE as far as it would rotate ANTI-CLOCKWISE.I noticed that the button locked down until the vertical markers aligned (see photo)I needed to press the button to start rotating CLOCKWISE but could release it soon after and it stayed LOCKED until it passed the COARSE setting.I then tested the grind on the FINE setting. It worked exactly as it should:Easy to use, value for money and producing a full-favoured brew.I’m very happy now.
