# Lelit Elizabeth My home espresso machine — the heart of [[My Coffee Gear]]. The Elizabeth (model **PL92T**) is Lelit's dual-boiler machine that punches well above its price: it brought true dual-boiler capability into the prosumer entry tier, which is usually the domain of single-boiler or heat-exchanger machines. For my full setup (grinder, scale, baskets, beans) see **[[My Coffee Gear]]**. For how I actually brew, see **[[Ristretto Recipe]]** and **[[Americano Recipe]]**. ## Why It's a Standout - **Dual boiler** — separate brew and steam boilers, so I can pull a shot and steam milk at the same time, each at its own optimal temperature. Rare at this price point. - **PID temperature control** — precise, stable brew temperature with an adjustable setpoint. - **Programmable pre-infusion** — gently saturates the puck before full pressure, improving extraction evenness. - **Programmable shot volumes** and a shot timer built into the display. - Compact footprint for a dual boiler. ## Specs | Spec | Detail | |---|---| | Model | PL92T | | Boiler config | Dual boiler (separate brew + steam) | | Brew boiler | ~0.3 L, PID-controlled | | Steam boiler | ~0.6 L, PID-controlled | | Temperature control | PID, adjustable setpoint (brew + steam) | | Pre-infusion | Programmable (time-based) | | Pump | Vibration pump | | Portafilter | 57 mm | | Group | Commercial-style with pre-heating | | Water | Removable tank (plumb-in not supported) | | Display | LCD with shot timer, programmable volumes, settings | ## Brewing With It - **Baskets:** I switch between 18 g and 20 g baskets, usually with a **bottomless (naked) portafilter** for extraction feedback. - **Recipe style:** [[Ristretto Recipe|ristretto]] — a tighter ratio and shorter yield than a standard 1:2. - **Dial-in / dose / yield:** *(record actual grind setting, dose, yield, and shot time here as I dial in each coffee)* - **Pre-infusion setting:** *(note the programmed pre-infusion time here once set)* ## Maintenance & Care - **Backflush** the group with a blind basket + detergent (e.g. Cafiza) periodically to clear the three-way solenoid and group of coffee oils. - **Descale** the brew and steam boilers on a schedule appropriate to local water hardness — using softened/low-mineral water lengthens the interval. - **Water quality matters** on a dual boiler: scale buildup is the main long-term risk. Filtered or remineralized low-hardness water is ideal. - Wipe the steam wand and purge it after every milk drink; keep the drip tray and screen clean. ## Notes & Tweaks - *(log any PID/pre-infusion setpoint changes, quirks, or fixes here)* ## See Also - [[My Coffee Gear]] — the full setup (grinder, scale, accessories) - [[Ristretto Recipe]] — my espresso base recipe - [[Americano Recipe]] — morning Americano - [[List of potential coffee machines]] — upgrade candidates - [[Coffee]] — the Area overview
