Q: Why Does My Pump’s Soft Start Trip Repeatedly?
A: Tripping usually indicates overload or voltage issues. Check these first:
- Is the power supply stable? Voltage fluctuations can trigger safety mechanisms.
- Are the impeller or pipes blocked? Mechanical resistance strains the motor.
- Does the display show error codes like “OL” (overload) or “UV” (undervoltage)?
SHUYI Tip: If resetting doesn’t work, our technicians can remotely analyze your system’s performance data.

Q: Why Does the Motor Overheat During Startup?
A: Overheating often results from:
- Mechanical Issues: Worn bearings or a seized impeller increasing friction.
- Electrical Problems: Incorrect voltage settings or a faulty capacitor.
- Environmental Factors: High temperatures in poorly ventilated areas.
Next Step: Avoid further damage—submit your system specs via our online form for tailored solutions.
Q: Should I Worry About Strange Noises from the Soft Start?
A: Unusual sounds like humming or clicking may signal:
- Loose internal components vibrating during operation.
- A failing cooling fan struggling to dissipate heat.
- Corroded connections causing electrical arcing.
Safety Note: Power down immediately if you hear buzzing or see sparks. Our team can guide initial checks via phone.

Q: Can I Repair the Soft Start Myself?
A: While minor fixes like tightening wires are DIY-friendly, contact professionals for:
- Electrical component repairs.
- Recurring issues after resetting.
- Complex parameter adjustments.

Q: How Often Should I Maintain My Pump’s Soft Start?
A: Preventive maintenance is critical:
- Clean dust and inspect connections annually.
- Conduct thermal imaging scans biannually.
- Replace capacitors every 5–7 years (usage-dependent).
