Frequently Asked Questions
How do I know if my coffee grinder burrs need to be replaced or if the machine just needs a calibration?
Inconsistent particle size, excessive static, and a noticeably bitter or burnt taste in your espresso are primary indicators of worn burrs. If your grinder takes significantly longer than usual to process a standard dose, or if the grounds are coming out clumpy and hot, the burrs are likely dull. We can inspect the physical cutting edges and replace them to restore a uniform grind profile.
My commercial coffee brewer is filling up very slowly and the temperature keeps dropping. What is causing this?
Slow filling and temperature drops are typically caused by heavy scale accumulation inside the boiler or a malfunctioning water inlet valve. Scale acts as an insulator, preventing the heating elements from transferring heat efficiently to the water. Our technicians can perform a complete teardown to safely remove the scale and inspect the heating elements and valves for proper functionality.
What causes water to leak from underneath my espresso machine during the brewing cycle?
Leaks from the bottom of a machine usually stem from a blocked drain box, a ruptured silicon or braided hose, or a failing expansion valve. Over time, coffee grounds can clog the drain tray lines, causing water to back up and overflow into the machine’s base. It is crucial to have this inspected professionally to prevent water from contacting internal electrical components.
Why is my espresso machine failing to build adequate steam pressure even though it turns on?
A lack of steam pressure is commonly tied to a faulty pressurestat, a failed heating element, or a stuck anti-vacuum valve. If the safety switches trip or the pressure sensor fails to communicate with the control board, the machine will stop heating before reaching steam temperature. We can safely test the electrical continuity of these components to pinpoint and replace the defective part.
How often should commercial coffee equipment undergo professional preventative maintenance?
To prevent unexpected breakdowns and maintain flavor quality, high-volume equipment should receive a professional preventative maintenance service every 6 to 12 months. This schedule varies depending on your water quality and daily throughput. Regular replacement of seals, gaskets, and valves keeps the machinery running reliably and extends its overall lifespan.
