PROBLEM:
WATER OVERFLOWING.
POSSIBLE CAUSE
SOLUTION
Turn power off and observe water level. If water continues to flow
into the heating tank, clean or replace leaky valve.
Disconnect wire from probe terminal. Touch the body of the heat-
ing tank with the terminal at the end of this wire. If water stops,
try cleaning the probe. Probe may have to be replaced.
Liquid level control board must be securely grounded through the
back of the board and the mounting bracket. Check for loose
connections at the terminals. Check for voltage across the inlet
valve terminals. If there is 110 to 120 volts present at the inlet
valve terminals when water level is touching the probe tip, replace
the L.L.C. board.
1 . Defective water
inlet valve
2 . Probe limed up
3 . Non-grounded or
loose terminal
connections at
liquid level con-
trol board
POSSIBLE CAUSE
SOLUTION
1 . Thermostat
turned
OFF
(or
set too low)
Check thermostat to make sure the shaft is knob is rotated clock-
wise to the desired temperature.
PROBLEM:
WATER DOES NOT REACH PROPER TEMPERATURE
POSSIBLE CAUSE
SOLUTION
PROBLEM:
WATER WILL NOT REFILL
1 . Water line closed
or clogged filter
2 . Valve coil burned
o u t
3. Grounded probe
4 . Defective water
level control
board
TROUBLE SHOOTING
Check the water system at your facility to make sure the line is
open. Replace the water filter.
Turn machine off. Disconnect wires from water inlet coil terminals
and connect a power cord to the terminals. Plug cord into a 120V
outlet and verify if water flows when plugged in and stops when
power is disconnected. If valve fails this test, replace valve.
When the water level gets below the probe tip, water should
automatically refill the unit. If not, pull wire off the probe termi-
nal. Water should now start flowing into the water boiler.
Disconnect wire from probe terminal. With a voltmeter, check
voltage at the water inlet coil terminals. This should read 110-120
volts. If no voltage is present, check liquid level control (L.L.C.)
board. Make sure the L.L.C. board is supplied by 120V across
terminals T2 & T3. The L.L.C. board is grounded to the body of
the machine by contacting the board to the mounting bracket.
Make sure board is grounded here. Check for loose connections
at terminals. Replace board.
