Troubleshooting RO Systems
| RO System does NOT start up | |
|---|---|
| Power cord not plugged in, Power outage | Check and connect power |
| Transformer burned out | Check the transformer input voltage/overload burned out |
| Insufficient water (water cut off) and inlet pressures | Check the inlet water pressure |
| Booster pump malfunction | Replace Booster pump |
| Post filter cartridges are clogged | Check if post filter cartridge is clogging the water flow |
| High pressure switch failure | Replace high pressure switch |
| Low pressure switch failure | Replace low pressure switch |
| Insufficient Output RO Water | |
|---|---|
| Insufficient water pressure coming out of booster pump | Replace booster pump |
| RO membrane filter element got clogged | Replace RO membrane |
| Insufficient water input | Check if the Stage 1,2 or 3 filter cartridge is clogged |
| Stage 1,2 or 3 filter cartridge is clogged | Check if the Stage 1,2 or 3 filter cartridge is clogged/replace |
| No or Little Decrease in TDS Value in Product Water | |
|---|---|
| RO membrane connector O-RING deformed with leakage | Replace O-RING |
| RO membrane ruptured/aperture enlarged | Replace RO membrane element cartridge |
| System NOT Treating Water After Replacing Filter Cartridge | |
|---|---|
| Air in the tubing (AIR) | Release the air in the tubing |
| Pressurized Motor Continues to Restart Frequently | |
|---|---|
| Outlet check valve is not blocking water completely | Replace check valve |
| Leakage in the tubing | Lock tight/replace tubing |
| Booster Pump Motor Burned Out | |
|---|---|
| Abnormal frequent startup and overheat | Replace booster pump |
| Pressurized Motor Junction Leakage | |
|---|---|
| Motor triangular diaphragm rupture | Replace booster pump |
| Motor Does NOT Pump Up the Pressure | |
|---|---|
| Air in the motor | Release the air |
| Insufficient water input | Check if water supply and post filters cartridge are clogged |
| RO Water Smells or Tastes Strange | |
|---|---|
| Inline active carbon is saturated | Replace inline activated carbon filter cartridge (polished filter) |
| Intermittent usage, water ceases flowing | Drain tank water/replace inline active carbon cartridge |
| Stage 1,2 or 3 filter cartridge Junction Leakage | |
|---|---|
| Filter housing not locking tightly | Lock each filter housing ( canister ) tightly |
| Filter housing o-ring deformed | Replace housing o-ring |
| Transformer Burning Smell | |
|---|---|
| Power input specification error/burned out | Check if power input complies with standard specs |
