GENERAL TROUBLE SHOOTING GUIDE
TROUBLE
Water does not enter the boiler.
Water enters boiler very slowly.
Water level in gauge glass fluctuates
up and down.
Boiler fails to build up pressure when
water level is proper and fuel switch is
turned on.
Boiler fails to reach full operating
pressure of 5 lbs. or 15 lbs.
POSSIBLE CAUSE
1. Water main shut-off.
2. Power not reaching unit.
3. Probes dirty.
4. Water level control board defective.
5. Solenoid valve defective.
1. Dirty strainer screen in solenoid
valve.
1. Top shut off on water gauge is
closed.
1. Check to see that circuit breaker in
main is turned on.
2. Check to see that contactors are
pulling in.
3. Current flow is broken at water
level control (ascertain with
continuity check).
4. Current flow is broken at pressure
control or high limit control switches
due to maladjustment or defect
(ascertain with continuity check).
5. Heating elements are defective.
1. Pressure gauge reads inaccurately.
2. Pressure control and high limit
control switches are out of
adjustment.
3. Safety valve not seating properly.
4. Contactor coils (one or both) not
energizing and closing circuit to the
heating elements.
REMEDY
1. Turn on.
2. Check main fuse or circuit.
3. Remove and clean.
4. See (page 8) for test procedure.
5. If 120V is verified at solenoid coil,
but fails to open, replace solenoid.
1. Clean or replace strainer screen.
Part No. 08-4871
1. Open.
1. Check for voltage at terminal block.
2. Check continuity of coil, if open
replace.
3. Check for voltage at L1 and L2,
replace if defective.
4. Readjust - to proper setting - refer
to instructions for readjustment,
replace if defective.
5. Replace if continuity check through
the circuit of each element shows
defective.
1. Replace.
2. Follow instructions for readjusting
or replace if defective.
3. Clean or replace.
4. Check - replace either contactor
coils or complete contactor - if
found defective. Measure
amperage at terminal block check
to be sure there is an even draw on
all three phases - see wiring
diagrams for correct AMP draw. If
uneven or zero amperage draw is
found on one of the three phases,
check for blown fuse. If fuse is OK,
shut off power, remove wires from
heating elements and run continuity
check - replace if defective.
