Start by turning the steam module off and unplugging from the wall socket, allow the module to cool before performing this service task. Remove the drain, tap connections and water supply to the module so you can pull unit from installed position.
-
Remove the top panel from the module using a #2 phillips drive or 2.5mm hex wrench depending on age of system could differ.
-
Remove the left and right side panels as well with the #2 phillips or 2.5mm hex wrench as shown.
-
Remove the back panel that also holds the cooling fan in place with the #2 phillips or 2.5mm hex wrench. The fan is plugged into the main board via a small black 3 pin connector, take care to remove this from the main board before removing the panel. There is also a temperature probe that is routed behind the main board, handle this with care.

Using a 1/4" nut driver remove the screw holding the electrical enclosure cover in place, then remove the cover to expose the components.
-
Using the #2 phillips or 2.5mm hex wrench, remove the grounding screw from the base plate as shown.
-
Use the long green ground wire from your kit and install it on the ground screw as shown with the other two grounding wires. Use the smaller of the two eyelet connectors here, the larger eyelet is for the boiler side. Be sure to tighten the screw down tightly so we have a solid ground connection.

Route the ground wire through the enclosure as shown (arrow). Remove the screw from the boiler to bracket as shown, could be 4mm hex or #2 phillips, this is where you will put the other end of the ground wire.
-
Install the eyelet on the boiler bracket as shown. Also make sure this connection is tight! It may be difficult to line up the screw through the bracket, you can loosen the other bracket screw to help shift the boiler back inline if needed.
-
Loosen the V- and ground terminals on the 5 volt and 24 volt power supplies located in the electrical enclosure. It may be hard to see the V- and ground terminals on the 5 volt supply, they are where the grey and green wires are attached. Then put the small green jumper wire between the V- and ground on both power supplies and tighten back down.

-
When finished it should look like the module in the photo. Be sure that all the wires are tight and no loose strands of wire are sticking out!
-
It is now safe to start putting the module back together in the reverse order.
-
Once you have finished putting all the panels back in place, and the unit re-installed, be sure to power up the module and check for proper operation. If all is well after all checks completed.... make a latte and enjoy yourself, good work!
