Charlie experienced an issue where grit from the water tank got sucked into the solenoid valve. He found an online video demonstrating how to disassemble the relevant part, remove the grit from the solenoid valve, and reassemble the machine, thus resolving the problem.
This video is a comprehensive review of the Rancilio Silvia Pro X dual boiler espresso machine. Charlie, the reviewer, discusses the machine's espresso quality, build, features (like variable soft pre-infusion), steam performance, value, and minor issues. The review is based on nearly a month of daily use.
Charlie's criticisms of the drip tray and cover include: the slats across the middle and side holes (similar to the previous Silvia model); the metal ramps to raise the drip tray, which while reducing splashing for espresso only, barely allows the steam arm to fit underneath even when flat; the lip at the front of the tray making it difficult to pull out without spilling; and the tendency for the steam wand to spray water onto the table when flushing the steam into the drip tray. He notes that these are minor issues that haven't significantly impacted his daily use.
The provided transcript does not offer a direct comparison of the Rancilio Silvia Pro X to other espresso machines in terms of espresso shot pulling capabilities beyond stating that it's a significant improvement over single boiler machines, even those with PID, due to its superior thermal stability. The reviewer highlights the consistency in brew temperatures achieved after a brief warm-up period. No other specific machine comparisons are made regarding espresso shot pulling alone.
