Rocket Espresso Mozzafiato Timer Type V Espresso Machine

Initial Setup

Fill the internal reservoir. Run water through the system without coffee. Allow 25–30 minutes for the machine to reach stable operating temperature. The vibration pump draws from the internal reservoir only — no direct plumbing option.

PID Temperature Control

The Mozzafiato Timer Type V features a PID controller for precise boiler temperature management. The PID display is mounted on the machine — set your target brew temperature in one-degree increments. Factory default is approximately 200°F (93°C).

Shot Timer

The built-in shot timer starts when the pump activates and displays elapsed time. Use it alongside a scale for recipe development and consistency.

Cooling Flush

Even with a PID, an HX machine can overshoot brew temperature after idle periods. Run a 2–3 second cooling flush before each shot if the machine has been idle for 10+ minutes.

PID vs. Temperature Surfing

The Mozzafiato Timer Type V's PID eliminates the need for temperature surfing required on non-PID HX machines. Set your target temperature, use a consistent cooling flush protocol, and your brew temperature will be stable and repeatable.

Vibration Pump Notes

The vibration pump produces slightly more noise than a rotary pump. This is normal and expected. Ensure the machine is on a stable surface to minimize vibration.

E61 Group Head Pre-Infusion

Rocket's modified E61 group incorporates pre-infusion — water gently saturates the puck at low pressure before full extraction begins. This is passive and automatic; no settings are required.

Daily Cleaning

Wipe the steam wand and purge after each use. Remove the portafilter and rinse the basket under warm water. Wipe the group head area and drip tray.

Weekly Backflushing

Backflush with the blind basket and espresso cleaner. Run 5–6 cycles of 10 seconds on / 10 seconds off, then 5–6 rinse cycles with plain water.

PID Controller

The PID unit requires no maintenance. If the display becomes hard to read, clean the screen area with a dry cloth.

PID Not Holding Temperature

Small temperature fluctuations (±2–3°F) are normal. Wider swings may indicate a boiler probe issue — contact SCG service.

Shot Timer Not Starting

The shot timer activates when the brew switch triggers the pump. If the timer doesn't start, check that the switch is fully engaged.

Shots Running Too Hot After Idle

Apply a longer cooling flush — 3–5 seconds — after extended idle. The HX circuit stores extra heat; the flush removes it before brewing.

Machine Running Dry

Monitor water level in the reservoir and refill before the machine runs dry. Running the pump dry can damage the pump and boiler.
