# Problem Possible Cause Remedy
1. EZFill System does
not power ON.
(Area around switches Does
NOT backlight.)
Apparatus (operator’s
panel) not receiving
power. ● Check apparatus operator's panel per manufacturer's
recommendations.
● See manufacturer's apparatus manual for troubleshoot-
ing procedures.
Blown fuse / disconnect
(between apparatus
and EZFill system). ● Check and replace with same size fuse. If fuse / dis-
connect blows a second time, system requires further
torubleshooting to determine cause.
● NEVER insert a larger size fuse.
Main power to EZFill
system not available. ● Check for main power at pins #1 (+9VDC...+32VDC)
and #8 (vehicle ground) on Smart-Switch. See Figures
6-3 and 6-4 on page 35.
● If power is available, replace smart-switch
● If power is not available, continuity test wire harness -
repair and/or replace.
2. EZFill system is ON,
but CLASS1 logo fails
to light when FILL or
FLUSH buttons are
pressed. Does pump/motor run
when FILL or FLUSH
buttons are pressed? ● If motor runs, possible defective LED - repair and/or
replace smart-switch.
● If motor does NOT run, see headings:
* Defective motor run relay
* Defective tank FILL sensor
* Bad motor
Defective motor relay
(Single Tank).
Note: For a Dual Tank system,
see Step 4 on page 38.
● Check for main voltage (+9VDC...+32VDC) at pin #30
on relay. See Figure 6-1 on page 33.
No voltage - see preceding Step 1 to verify main power
is provided, repair and/or replace accordingly.
● If voltage is OK, check for voltage from smart-switch at
pin #85 on relay. See Figure 6-1 on page 33. No volt-
age - replace smart-switch.
● Check for voltage at pin # 87 on relay. Low or odd volt-
age indicates possible motor stall leading to possible
blown fuse / disconnect. No voltage indictaes defective
relay - replace.
Defective motor. ● Check for voltage across motor contacts. Low or odd
voltage indicates possible motor stall leading to possi-
ble blown fuse / disconnect.
● Repair and/or replace motor.
Defective FULL tank
level sensor.
Note: A defective sensor can
prevent pump motor operation
by providing a constant tank
FULL signal.
● Using an ohmmeter, check for current across sensor
switch leads.
● Low ohm reading is present when switch is activated
Zero (0) reading when switch is released, indicating a
FILL requirement.
