Maintenance Tips

• Daily wash & sanitize (critical): Empty completely, then clean with warm soapy water, rinse, and use a non-chlorine sanitizer. Do not submerge the server.
• Clean sight gauge tube daily: Remove the mechanical sight glass tube and shroud, then brush thoroughly to prevent coffee oil buildup that can cause false level readings.
• Flush brew-through system: Run a hot water cycle into the server daily and immediately drain through the faucet to reduce residue buildup in internal lines.
• Disassemble faucet regularly: Clean faucet stem, spring, seat cup, and bonnet to prevent sticking, slow flow, and leaks.
• Clean lid fill tube & gaskets: Brush the brew-through lid tube and silicone fittings to prevent clogging and maintain smooth filling during brewing.
• Wipe exterior only (no pressure spray): Use a soft cloth with mild detergent—avoid jets or submersion to protect vacuum insulation and seals.
• Inspect sight gauge seals: Check washers and seals regularly; worn parts can cause leaks or inaccurate level visibility.
• Avoid chlorinated cleaners: They can damage stainless steel and void warranty on ThermoFresh servers.
• Air dry fully after cleaning: Prevent trapped moisture to avoid odor formation and microbial growth.
• Handle carefully during transport: Vacuum insulation is durable but can lose efficiency if seals are compromised or impact-damaged.
