Does anyone know how to contact Klarstein in the UK? I have tried the only number I can find - 01203 318 3951, but I seem to be blocked from calling it. (Tried two different mobiles but both the same). My problem is, I bought a brand new Brauheld Pro 35 last month. Tried it this morning for the first time. Set up 4 steps with the first step to notify me when the temperature gets to 52ºC. When the controller said 43ºC the water started to boil. Obviously faulty or have I set up the recipe steps wrong?
