5.1 Cleaning
- Daily Cleaning: Wipe the exterior of the unit with a soft, damp cloth. Clean the drip tray regularly to prevent water buildup and stains.
- Interior Cleaning (Hand Wash): For thorough cleaning of the inner tank, unplug the unit and allow it to cool completely. Drain all water from the tank. Use a mild detergent and a soft brush or sponge to clean the interior. Rinse thoroughly with clean water.
- Faucet Cleaning: Periodically clean the dispensing faucet to remove any mineral deposits or residue.
- Do Not Use: Abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the stainless steel surfaces.
5.2 Descaling
Over time, mineral deposits (limescale) can build up inside the heating elements and tank, especially in areas with hard water. Descaling is recommended every 1-3 months, depending on water hardness and usage.
- Unplug the dispenser and allow it to cool completely.
- Drain all water from the tank.
- Prepare a descaling solution according to the manufacturer's instructions (e.g., citric acid solution or commercial descaler).
- Pour the descaling solution into the tank.
- Allow the solution to sit for the recommended time (usually 30 minutes to a few hours). Do not heat the solution unless specified by the descaler's instructions.
- Drain the descaling solution completely.
- Rinse the tank thoroughly several times with fresh water to remove all traces of the descaling solution. Dispense several cups of clean water to flush the system before resuming normal use.
6. Troubleshooting
This section addresses common issues you might encounter with your hot water dispenser.
