WATT Equipment We Repair — By Category
WATT Product Lines We Repair
Our engineers are trained on the full WATT product range. Below are the major product families we service.
WS-Series Soft Starters
WATT WS-Series soft starters reduce inrush current and mechanical stress on motors in pump, fan, and compressor applications. Common issues include thyristor firing failures, control board corrosion from moisture, and nuisance trip faults in high-ambient environments.
WATT VFD Energy Drives
Variable frequency drives with integrated energy metering and harmonic filtering for cement mills, sugar factories, and textile spindle motors. Typical faults: capacitor bank degradation, IGBT module burnout, and encoder communication loss in multi-motor arrays.
WATT Control Modules (ECU)
Embedded control units and parameter cards for WATT drives, managing soft-start ramps, braking sequences, and thermal protection. Prone to EEPROM corruption, relay stickiness, and potentiometer drift in factory-floor dust environments.
WATT Power Factor Correction Units
Static VAR compensation and capacitor-bank systems for reducing reactive power penalties in Indian industrial plants. Repair focuses on blown capacitor cells, thyristor short-circuits, and control relay failures under load-switching stress.
WATT Braking Resistor Assemblies
High-power dynamic braking resistors for energy dissipation in VFD stop sequences, especially in hoists, elevators, and punch presses. Failures include wire-wound resistor open circuits, mounting bracket corrosion, and thermal fuse nuisance trips.
Why Choose Synchronics for WATT Repairs?
PCB-Level Expertise

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common WATT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in WATT equipment arriving at our workshop.
- ✓WATT soft starter thyristor misfiring or no output — WATT soft starters rely on synchronized thyristor gate signals. Misfiring occurs due to control board capacitor leakage, optocoupler failures (TLP291 series), or trigger pulse generation faults. Indian humidity and industrial dust aggravate PCB trace corrosion.
- ✓WATT VFD capacitor bank swelling or leaking — Electrolytic capacitors in WATT ED-Series drives degrade in high-ambient conditions (40°C+ typical in Indian industrial zones). Ripple current stress and inadequate cooling cause early electrolyte loss and pressure relief venting.
- ✓WATT ECU control module EEPROM corruption (no parameter memory) — Power transients, lightning strikes, and inadequate surge protection corrupt WATT ECU flash memory. Industrial sugar mills and textile plants report parameter loss after grid disturbances, forcing manual re-entry of soft-start curves.
- ✓WATT PFC unit capacitor bank shorted or blown — Overvoltage transients on incoming mains, switching harmonics from adjacent VFDs, or internal capacitor cell rupture cause PFC unit failures. Indian power quality issues (20%+ voltage fluctuations) stress WATT PFC systems beyond nominal ratings.
- ✓WATT braking resistor open-circuit or thermal fuse nuisance trip — Wire-wound resistor elements fatigue under repeated deceleration cycles (hoists, elevators). Thermal fuses on WATT BR-Series units trip prematurely if cooling air intake becomes blocked by foundry dust or textile lint.
- ✓WATT drive communication loss or CAN/Modbus timeout — Encoder cable damage, connector oxidation, or control module watchdog reset during parameter upload. Multi-drive arrays in sugar mills report intermittent CAN-bus dropouts when WATT modules share ground planes inadequately.

Frequently Asked Questions — WATT Repairs
Do you repair WATT equipment anywhere in India?+
Yes. Synchronics repairs the full WATT product range — soft starters, VFDs, control modules, PFC units, and braking resistors. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Nashik, Jalgaon, and all major cities. All repairs are performed in our ISO-certified facility in Vadodara, Gujarat, with 3-7 day turnaround for most units.
What is the typical repair cost for a WATT WS-Series soft starter?+
WATT WS-Series soft starter repair costs typically range from Rs 8,000 to Rs 25,000 depending on fault severity. Thyristor replacement and trigger-card repair cost less; full capacitor-bank replacement with module retuning costs more. Synchronics provides free diagnostic assessment within 24 hours of arrival. We accept trade-in of defective cards and offer 12-month warranty on repairs.
Can Synchronics reprogram WATT ECU modules with custom soft-start curves for my sugar mill?+
Absolutely. Synchronics holds WATT factory programmer licenses and maintains curve templates for pumps, fans, compressors, and sugar-processing equipment. We reprogram WS-Series and ECU modules with custom ramp times, current limits, and bypass frequencies matched to your motor load. On-site commissioning available for multi-drive installations in Indian plants.
Do you stock WATT spare parts or only repair existing boards?+
We stock genuine WATT optocouplers (TLP series), thyristor modules, power capacitors, and control relays. For WS-Series and ED-Series drives, we maintain inventory of common replacement cards. For rare or obsolete WATT components, we source from international distributors within 5-10 business days. All parts come with authenticity certification and warranty.
What warranty do you offer on WATT repairs, and do you provide preventive maintenance?+
Synchronics provides 12-month parts and labor warranty on all WATT repairs. We also offer preventive maintenance contracts for sugar mills, textile plants, and cement factories — including annual thermal imaging, capacitor health testing, and firmware updates. Preventive plans cost 5-8% of new equipment value annually and reduce unplanned downtime by 60%.
How do I send my WATT unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a WATT drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on WATT repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your WATT unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
