TROUBLE SHOOTING, CONTINUED
PROBLEM: WATER NOT FLOWING FROM SPRAYHEAD
SOLUTION
POSSIBLE CAUSE
Remove sprayhead and clean. Clean the sprayhead fitting.
Check water level in tank. If water is not flowing into the tank,
review steps 1 thru 4, previous page.
Check the continuity between terminals WHT & BREW VLV.
When the BREW button is pressed, there should be solid conti-
nuity between these two terminals. If not, replace the mem-
brane control panel (see the instructions below).
Make sure the board is receiving 110 to 120 volts at terminals
BREW VLV and WHITE when BREW switch has been pressed.
There should be 110 to 120V going to the dump valve. If not,
then the control board is faulty.
If the control board is functioning properly (step 14), check the
dump valve. Measure voltage across the two terminals of the
valve coil. You should read 110 to 120 volts. Check also for
clogging or lime deposits. Clean if possible. Replace valve or
coil.
12. Sprayhead clogged
13. Water level is too low
in heating tank
14. Defective control board
15. Defective dump valve
or coil
CODE:
PROBLEM: WATER IN TANK DOES NOT GET HOT
OR WATER TEMPERATURE TOO LOW
POSSIBLE CAUSE
SOLUTION
CODE:
Make sure unit is on; power cord plugged in. Toggle switch is
on. Breaker is on.
Remove the sensor and squeeze a dab of silicone compound
(part no. WC-5229) between the sensor and the tank body.
Make sure the fastening nut is secure. Check the wire for
damage.
Check element for continuity and or check with clamp amme-
ter. This should show a reading of approximately 15 amps
(depending on element wattage). If no power is going through
element, replace the heating element.
If checks #8, #9 and #10 are normal, the control board is not
operating correctly. Replace the microprocessor assembly (#8,
figure 6.).
8. Power is off
9. Defective or loose heat
sensor
10. Burned out heating
element
11. Defective control
board
REPLACING THE MEMBRANE CONTROL PANEL
IMPORTANT - This procedure requires careful positioning of the membrane control panel. Improper
application of the new part will ruin the membrane when you try to lift it again. You will have to acquire an
additional panel to complete the task.
TEST
Before you actually remove the old membrane, test the old one by using your new membrane. Your old
one may be okay.
