Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Significant loss of turbine pressure
MediumSymptoms: Weak agitation at the turbine.
Root cause: Blocked water inlet holes under the pump, or the pump body not fully submerged (low water level).
Turbine will not start when switched on
HighSymptoms: No turbine operation.
Root cause: Power-source fault, or a faulty switch, fuse, GFI cord or main circuit.
Turbine stops during use (thermal overload)
MediumSymptoms: Turbine shuts off, resumes after cooling.
Root cause: Blocked motor ventilation holes or excessive current load; the motor's thermal overload protector has tripped.
Hard-water scale on moving parts
LowSymptoms: Rising noise, reduced turbine performance over months.
Root cause: Mineral build-up damaging the turbine assembly moving parts.
Tank or plumbing leak / drain fault
LowSymptoms: Water around the base, slow drain.
Root cause: Worn drain valve or fill/overflow fittings.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Loss of turbine pressure
- Check the water inlet holes underneath the pump and clear any foreign material.
- Add water so the pump body is completely submerged.
- Restart and check agitation.
- Descale if mineral build-up is present.
- Confirm normal turbine pressure.
Symptom: Turbine will not start or stops
- Check the power source and reset the GFI.
- Have a qualified technician check the switch, fuses, GFI cord and main circuit.
- Clear the motor ventilation holes.
- Let an overheated motor cool - it restarts automatically.
- Confirm continuous operation after clearing the cause.
