  1. Turn the power switch to the off position.
    • Turn the power switch to the off position.

    • Shut off the water supply to the steam module.

    • Actuate the steam tap, and allow the tap to steam until all pressure has been relieved from the module. Allow the module time to cool.

    • Boiler water will be hot unless allowed first to cool. Take great care to avoid scalding or burns from direct contact with the water!

  2. Using a 2.5mm hex wrench or #2 phillips, remove the screws that fasten the top and right side panels of the module. Remove both panels. Using a 2.5mm hex wrench or #2 phillips, remove the screws that fasten the top and right side panels of the module. Remove both panels.

  3. Be absolutely sure that the boiler is cooled and depressurized before performing the next step! Using a 13mm open end wrench, hold the sight glass drain fitting in place while using a 5mm hex wrench to remove the drain plug.

    • Using a 13mm open end wrench, hold the sight glass drain fitting in place while using a 5mm hex wrench to remove the drain plug.

    • Hold a container capable of collecting at least 3 liters of water below the drain fitting, and allow the boiler water to drain into the container.

    • Replace the plug once the boiler has finished draining.

  4. Follow the wiring back from the heating element on the right hand side of the boiler, and disconnect both wires. Using a 7/8" or adjustable wrench, unscrew the heating element from the boiler as shown.

    • There may be some residual water in the boiler. It helps to keep a rag handy to soak up any water that escapes.

  5. Apply the included liquid thread sealant to the threads of the new heating element. This prevents water from leaking through the threads after installation. Alternately, teflon thread tape may be used in substitution of the liquid sealant. Liquid sealant is preferred, however.

    • Install the new heating element very tightly using a 7/8" or adjustable wrench.

    • Connect the wires from the heating element, as they were removed in the previous step.

  6. Turn on the water supply to the steam module. Turn the power switch counter-clockwise to the left position, and allow the boiler to fill. Once the level has filled approximately half of the sight glass, the boiler will cease filling.
    • Turn on the water supply to the steam module.

    • Turn the power switch counter-clockwise to the left position, and allow the boiler to fill. Once the level has filled approximately half of the sight glass, the boiler will cease filling.

    • At this point, the power switch can be turned clockwise to the right position, which will begin to heat the boiler.

    • Test that the module is functioning once it has reached set temperature. This process will take approximately 10 minutes.

    • Inspect the area around the heating element for any signs of leakage. If leaking, the element may need to be tightened further. The machine should be turned off, depressurized, and element wiring disconnected before attempting to further tighten the element.

  7. Replace the top and right side panels, and their accompanying screws. Great work! Give yourself a high five!
