Hydrim L110W Troubleshooting ED & EF Error Codes
Error code ED indicates a dosing system failure.
1.
Check cleaning solution box for solution and check for a kinked tubing.
2.
Remove the right side cover.
3.
Disconnect tubing connected to suction side of dosing pump. Verify that cleaning solution
is flowing to the dosing pump. Flush lines or flow switch as needed.
4.
Connect a voltmeter to the red & blue wires connected to the dosing pump. Set the meter to
read line voltage (208-240VAC). Start a device test cycle, with the unit OFF hold in P2 &
P3 and turn the power switch ON and release all buttons. The display should read P5 & 8.
The unit will fill the chamber with water then the dosing pump should run for 20 seconds.
While the dosing pump is running the meter will read line voltage. If the meter reads line
voltage and the dosing pump does not turn, replace the dosing pump (#13634.00).
Note:
Dosing Pump motor should read approximately 60 ohms resistance.
If the meter does
not read line voltage replace the Slave Controller (#13475.04) first then the Master
Controller (#13475.03) if needed.
5.
If the Dosing Pump runs and ED still appears follow the instructions below for error code
EF.
6.
If the Flow Switch tests good and ED still appears with the Dosing Pump running, replace
the Dosing Pump (#13634.00) low output.
Error code EF indicates a shorted Flow Switch.
1.
If the Flow Switch is white and mounted horizontally, replace with new black flow switch
and mount new switch vertically.
2.
Disconnect tubing connected to suction side of dosing pump. Verify that cleaning solution
is flowing to the dosing pump. Flush lines or flow switch as needed.
3.
Disconnect the wires from the flow switch and connect an ohmmeter to the wires. Start a
device test cycle, with the unit OFF hold in P2 & P3 and turn the power switch ON and
release all buttons. The display should read P5 & 8. The unit will fill the chamber with
water then the dosing pump should run for 20 seconds. While the dosing pump is running
the meter should read less than 1 ohm (continuity). If reading is bad replace flow switch
(#01-111474S).
