DE1 Descaling Instructions 2026-09-07

DE1 Descaling Instructions

 Read Me First If you use soft enough water (TDS below 120 ppm), you only need to descale your machine once a year or every 2 years. If you use distilled or RO-filtered water, you don't need to descale your machine. The best way to determine this is to measure the TDS of your water. If there is a scale buildup issue, you can use distilled water or sufficiently soft water (TDS below 120 ppm) for descaling. Otherwise, the acid will be buffered by the hard water and become less effective. Use CITRIC ... [more]

Water recommendations for the DE1 and Bengle 2025-11-24

Water recommendations for the DE1 and Bengle

 The water used in espresso machines is easily the single most important factor for their longevity and functionality - and our machines are no exception. Using the wrong water can lead to scale buildup, causing heater failures which require sending the machine back to our Hong Kong factory for repair - failures we cannot cover under warranty. The good news: Our machines are designed to safely use reverse osmosis (RO) or distilled water, either of which is actually the ideal water choice. With sufficiently soft water (under approximately 30ppm TDS) there is no need to ever descale, since no scale will build up in the machine. This document provides specific water recommendations based on your water source, guidance on when descaling is necessary, and explains why our machines benefit from softer water than typical espresso machines.
