When a production line in a food processing plant goes down, every hour counts. Perishable products don’t wait. Over 20+ years, we’ve carried out hundreds of machine repairs in Swiss food processing facilities — from failed pumps to complete drive rebuilds. This article shares what we’ve learned.
Why Machine Repair in Food Processing Is Different
In a metalworking shop, a broken machine can often wait a few days. In food processing, that’s not an option:
Perishable products: Meat, dairy, and fresh products have tight time windows. A production line down for 8 hours can jeopardize an entire day’s batch.
Hygiene requirements: Repairs must be executed without creating contamination risks. Metal shavings, lubricants, or unsuitable replacement parts have no place in the food production zone.
Cost impact: Downtime costs of CHF 5,000 to 50,000 per hour are not uncommon — depending on plant size and product. A fast, professional repair is an economic necessity.
Documentation: Every repair must be documented. Material certificates for replacement parts, welding protocols, and a description of measures taken are standard requirements.
The 5 Most Common Machine Failures
From thousands of service calls, we know the typical failure causes in Swiss food processing plants:

1. Bearing Failures on Conveyors and Drives
Bearings are the most frequently wearing components in food production. Moisture, cleaning chemicals, and high loads drastically shorten their lifespan. Signs: unusual noises (grinding, knocking), elevated temperature at the bearing housing, vibrations.
Repair time: 2–6 hours (if replacement bearings are available) Typical cost: CHF 800–3,000 including parts and labour
2. Pump Failures
High-pressure pumps in washing systems, dosing pumps for cleaning agents, and product transfer pumps — pumps are the heart of many systems. Failed mechanical seals, cavitation, and worn impellers are the most common causes.
Repair time: 3–8 hours Typical cost: CHF 1,500–5,000
3. Electrical Failures (VFDs, PLCs, Sensors)
A failed variable frequency drive shuts down the entire motor. Moisture damage in control panels, defective sensors, or communication problems between the PLC and peripherals are frequent causes.
Repair time: 1–4 hours (sensor), 4–12 hours (VFD replacement) Typical cost: CHF 500–8,000
4. Pneumatic Failures
Leaking cylinders, failed solenoid valves, or contaminated air preparation — pneumatic systems are sensitive to moisture and contamination, both common in food production environments.
Repair time: 1–4 hours Typical cost: CHF 500–2,500
5. Mechanical Damage (Chains, Belts, Flights)
Chain wear, broken flights, or torn conveyor belts result from normal wear — but are accelerated by missing maintenance. In meat processing, foreign objects (bone fragments, packaging remnants) are an additional damage cause.
Repair time: 2–8 hours Typical cost: CHF 1,000–5,000
The Emergency Repair Process
At VLD Service, we follow a structured 5-step process:
Step 1: Remote Diagnosis (0–30 minutes)
Our technician takes the symptoms by phone or video: error message, noises, time of failure, last maintenance. In many cases, we can narrow down the probable cause and bring the right spare parts.
Step 2: Travel (30 min–4 hours)
From Wangen bei Olten, we reach most locations in German-speaking Switzerland within 2 hours. Interventions in Ticino and French-speaking Switzerland available on request. Our service vehicle is stocked with the most common spare parts and tools.
Step 3: On-Site Diagnosis (15–60 minutes)
Systematic troubleshooting: visual inspection, measurements (current, pressure, temperature, vibration), reading PLC fault logs. Only when the cause is clear does the repair begin.
Step 4: Repair
The actual repair — from bearing replacement to pump overhaul to VFD swap. All work is carried out in compliance with food safety hygiene requirements.
Step 5: Test Run and Documentation
The system is tested under production conditions. Only when everything runs flawlessly do we hand back to the operator. A service report with cause, measures, and recommendations follows within 24 hours.
What Does Machine Repair Cost?
Costs depend on the scope of damage. Reference values for Switzerland:
| Repair Type | Time Required | Cost (incl. parts) |
|---|---|---|
| Sensor replacement | 1–2 h | CHF 500–1,500 |
| Bearing replacement | 2–6 h | CHF 800–3,000 |
| Pump overhaul | 3–8 h | CHF 1,500–5,000 |
| VFD replacement | 4–8 h | CHF 3,000–8,000 |
| Chain repair | 2–6 h | CHF 1,000–4,000 |
| Complete drive rebuild | 6–16 h | CHF 5,000–15,000 |
Key insight: These costs are a fraction of the downtime cost. A pump repair for CHF 3,000 at a plant generating CHF 10,000/hour in production value pays for itself in 20 minutes.
Repair vs. Preventive Maintenance
The best repair is the one that’s never needed. A structured maintenance programme reduces unplanned failures by 60–80%. This means:
- Monthly inspection: Bearings, pumps, drives — check for noise, temperature, and wear
- Quarterly maintenance: Replace wear parts (seals, filters, V-belts)
- Annual overhaul: Complete inspection with documented protocol
A maintenance contract with VLD Service typically costs far less than a single unplanned repair — individual quote available on request.
