Troubleshooting
Problem Cause Check
Primary Voltage Circuit C. Wiring Connections With power off, check continuity of circuit through each
point in the circuit. If a break in the circuit is found,
repair. After repair, recheck with continuity light with
power off. Turn power on and check with an amp meter.
D. Burned or Broken Wiring With power off, check continuity of circuit through each
point in the circuit. If a break in the circuit is found,
repair. After repair, recheck with continuity light with
power off. Turn power on and check with an amp meter.
Verify wire size is sufficient for amp draw.
E. Contactor Contact Points If burned or dirty, clean with fine emory paper. If burned
through, replace. If not engaging completely,coil may be
weak. Replace.
F. Elements Shorting or Open Circuit With power using a continuity tester, check to see if an
element is burned out between each point. If power is
on, a volt meter may be used. If an element is bad,
replace.
Low Water Condition A. Circulating Pump Clean or replace all filters or screens to assure proper
water flow through them.
B. Water Makeup Supply Check to see that your supply water has not been shut
off or that there are no restrictions in the line leading to
the boiler.
C. Leaks in the System Check piping for any leaks.
Scale Formation Elements A. Hardness, Salt, Precipitation Softener perfomance
B. High Dissolved Solids Blowdown Schedule
Poor Steam Quality A. High Alkalinity in Boiler Water Adequate blowdown schedule or over feeding of water
B. High Organics in Boiler Water treatment chemicals
C. High Total Dissolved Solids in Boiler Water
