The high temperature limit switch is a safety device mounted on the boiler — it trips and cuts power to the heating element if the boiler temperature exceeds 130°C, protecting the machine from thermal runaway and component damage. Unlike a standard thermostat, this is a trip-free safety device, meaning it cannot be reset while the fault condition is still present.\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: L276.01 \/ LAML276.01\u003c\/li\u003e\n\u003cli\u003eTrip temperature: 130°C\u003c\/li\u003e\n\u003cli\u003eType: Trip-free (safety thermostat)\u003c\/li\u003e\n\u003cli\u003eApplication: Boiler high temperature safety cutout\u003c\/li\u003e\n\u003cli\u003eWeight: 200g\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible La Marzocco Espresso Machine Models\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGB5\u003c\/li\u003e\n\u003cli\u003eGS3\u003c\/li\u003e\n\u003cli\u003eKB90\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis part may also fit additional La Marzocco models.

Under normal operation it remains closed (allowing current to flow to the heating element). If the boiler overheats beyond 130°C — due to a failed thermostat, low water level, or scale buildup — the limit switch trips open, cutting power to the element and preventing damage. Because it is trip-free, it will not reset until the fault is identified and the machine has cooled, preventing accidental restart under unsafe conditions.\u003c\/p\u003e\u003ch3\u003eWhen Should You Replace the Temperature Limit Switch?\u003c\/h3\u003e\u003cp\u003eReplace this limit switch if your La Marzocco machine is showing any of the following: the machine has no heat and the main thermostat tests as functional, the limit switch has tripped and will not reset after cooling, continuity testing across the switch terminals shows an open circuit, or the switch body is visibly damaged or corroded.\u003c\/p\u003e\u003ch3\u003eImportant: Diagnose Before Replacing\u003c\/h3\u003e\u003cp\u003eA tripped limit switch is a symptom, not always the root cause. Before replacing, investigate why it tripped — common causes include a failed main thermostat, low water in the boiler, or heavy scale buildup on the heating element. Replacing the limit switch without addressing the underlying fault may result in it tripping again. Bear Coffee Machine can perform a full boiler diagnostic if needed.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between a thermostat and a high temperature limit switch?\u003c\/strong\u003e A thermostat actively regulates temperature by cycling the heating element on and off during normal operation. A high temperature limit switch is a one-shot safety device — it only activates if the boiler exceeds a dangerous temperature threshold, and is trip-free so it cannot be bypassed while the fault persists.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine La Marzocco part?\u003c\/strong\u003e Yes — this is a genuine OEM La Marzocco component (part number L276.01 \/ LAML276.01) meeting La Marzocco’s quality standards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan Bear Coffee Machine diagnose and replace this for me?\u003c\/strong\u003e Yes — we offer in-house repair and servicing for La Marzocco machines.
