The Homend Pottoman 1840H (and its UK/International counterpart, the 1840UK) is the core smart model in Homend’s Turkish coffee lineup. It is specifically designed to replicate the traditional "slow-cooked" texture and foam of Turkish coffee while offering fully automatic safety features.   ## Key Specifications Feature Details Model Number 1840H (TR) / 1840UK (Intl) Power 535 Watts Capacity 5 Cups (450ml reservoir) Safety Features Overflow protection, Boil-dry protection, Auto shut-off Color Black (Siyah) ## Detailed Features Smart Sensors (Anti-Overflow): This is the machine's most praised feature. It uses infrared sensors to detect the rising foam and stops the brewing process instantly to prevent the coffee from spilling over the sides.   Special Heat Balance: To achieve the "köz" (embers) taste, the machine avoids rapid boiling. Instead, it cycles the heat to brew the coffee at the ideal temperature, ensuring a thick layer of foam (köpük).   Voice Warning System: Unlike basic electric pots, the 1840 series includes an audible warning system (or voice alerts in the 1840UK model) that notifies you exactly when the coffee is ready to be poured.   Auto Shut-Off: For energy efficiency and safety, the machine shuts down automatically the moment you remove the pot from its base.   ## Critical Usage Tips for the 1840H The "Cold Water" Rule: For the best foam, always use cold, filtered water. Warm or hot water will brew too quickly, resulting in less foam.   No Milk: The 1840H is strictly for water-based coffee. Do not use milk in this model as it can scorch the bottom and damage the sensors. (If you want milk-based coffee, you need the Pottoman Milk In 1873H model).   Pre-Stirring: Mix your coffee and water in the pot before you place it on the machine. Once it starts brewing, do not stir it. Maintenance: Hand-wash the coffee pot only. The dishwasher will destroy the specialized coating and the sensor contact points on the bottom of the pot.
