Problem 8 - No steam pressure.
If no steam pressure is present in the steam boiler, there are several items to check. The main
power switch, the heating element, and the pressure switch.
Solution 1 - Ensure the main power switch is in the proper postition.
1. For power to run to the heating elements, the main power switch must
be in the “2” or “Run” position.
If the switch is in the “1” or “Fill” position, all other functions except the
heating elements will operate. This may lead the operator to believe the
machine is operational.
Solution 2 - Ensure the heating element is receiving voltage and operational.
1. Remove the machines top
and left side panel.
2. Using a multi-meter equipped with an amp clamp, check the am-
perage the element is pulling. To determine the proper amperage
an element should pull, divide the wattage of the element by the
voltage going to the element.
If the amperage is zero, turn the machine off, disconnect the leads
powering the element, switch the multi-meter to ohms and check
the element for continuity. If the continuity is zero, the element is
damaged and must be replaced.
If the amperage is lower than it should be. Switch the multi-meter to
ac voltage and check the voltage at the elements leads. The proper
voltage reading should be between 208-230. If the voltage is too
low, check the pressure switch for proper operation (Problem 8,
Solution 3). You can also check the wall outlet to ensure voltage is
3. If the heating element requires replacement, following the instructions on the following page.
