F-801 Internal RO System by GE Osmonics
12552e - 27 Feb 04 5- 5 Troubleshooting
5.1 RO Fails to Run
1. Power off.
a. Check position of power switch.
b. Check power cord (plugged in).
c. Check outlet and circuit breaker/fuse panel for power with voltmeter.
d. Check fuses in RO monitor panel.
2. Improper line voltage.
a. Verify that line and equipment voltages are compatible.
b. Check to make sure that combination of RO and other equipment that may be
plugged into the same outlet are not overloading the circuit.
3. Loose electrical connections.
a. Check all wiring connections to verify solid connection.
b. Verify that plug is securely connected to outlet.
4. Pump motor inoperative.
a. Verify that voltage supply is correct and motor is wired for correct voltage.
Correct as necessary.
b. Motor thermal overload switch tripped (most motors have automatic internal
reset). Motor will restart when it cools approximately 10-15 minutes. Correct
reason for the overload.
c. Remove pump head and try restarting motor.
d. Replace motor.
5. Pump inoperative.
a. Inspect pump and motor coupling for wear.
b. Clean any debris or liquid from connection area.
c. Replace pump.
d. See 5.4.
5.2 RO Runs Intermittently
1. Loose electrical connection.
a. Verify that all wiring connections are secure.
b. Verify that plug is securely connected to outlet.
2. Pump pressure too high.
a. Adjust pressure at pump head.
b. Check waste flow-path for obstruction.
c. See 5.1.4
d. See 5.1.5
3. Thermal overload trips
a. Verify line voltage and motor amperage draw.
b. Disassemble pump/motor at clamp and inspect coupler for wear.
c. Pump pressure too high (see 5.2.2).
