Troubleshooting, Common Faults & Solutions
Motor does not rotate
Likely Cause: Disconnected wire or blown fuse.
Action / Part: Check wiring and power supply voltage.
Pump does not discharge
Likely Cause: Air lock in pump head or suction lift too high.
Action / Part: Release air via air vent screw or check suction piping.
Flow rate fluctuates
Likely Cause: Debris in valve set or worn valve balls.
Action / Part: Clean or replace Valve Balls (L0093) and Seats (L0095).
Liquid leakage from pump head
Likely Cause: Damaged diaphragm or loose bolts.
Action / Part: Replace Diaphragm (L0109) and retighten head bolts (L1166).
Abnormal noise
Likely Cause: Worn worm gear or bearings.
Action / Part: Inspect Drive Unit and replace Bearings (L1110).
