Possible Causes

Steam boiler not heating due to failed element, Incorrect PID or pressurestat setting, Faulty steam boiler thermostat, Scale buildup reducing heat transfer

How to Fix / Troubleshooting

Safety first: Turn OFF, unplug, and allow cooling before internal checks.

  • Check pressure gauge: On models with a steam pressure gauge, verify if it rises to the normal range (typically around 1–1.5 bar). If it stays near zero, the boiler is not heating.
  • Verify steam mode: Ensure the steam function is enabled and that the machine has had enough time (10–15 minutes) to build pressure.
  • Inspect heating circuit: Follow the steps in the general heating failure section to test the steam boiler element and thermostat.
  • Descale steam boiler: If the boiler heats but steam is weak, heavy scale may be insulating the element. Perform a descaling cycle focusing on the steam boiler, following Lelit’s guidelines.
  • Check steam tip: Remove and clean the steam wand tip; blocked holes can make steam appear weak.
