Daily operator care and work requiring qualified service are assigned separately. Regulated work stays within KONGRA’s legal scope or is coordinated with properly licensed independent contractors.

Sveba-Dahlen C152 door and hinge service access
During a completed Sveba-Dahlen C152 rack-oven service, two customer-supplied door hinge assemblies were replaced. The door was supported and removed as needed, then reinstalled and aligned; closing and alignment were checked, the oven was reassembled, and a final operational check was performed.

Rack oven: recorded service result

A documented rack-oven service record confirms door hinge work, closing and alignment checks, and a final operational check. Door wear and sealing belong in subsequent condition reviews. The photograph above shows service access, not the final test.

Rack oven service and findings

Belshaw fryer: recurrence recorded

An ignition complaint initially responded during diagnosis and was later reported to recur. Follow-up observation was needed; a lasting repair was not established. A maintenance record should retain that open item rather than close it after one successful start.

Fryer ignition diagnostics

A documented Avantco slicer inspection shows why oil-level checks and new carriage-drive noise belong in a preventive-maintenance routine. Read the slicer lubrication and gearbox field case.

Visit records

A clear handover after service

For an intermittent fault before service, use the equipment failure observation log to retain the mode, load and display message separately from the maintenance plan.

The report separates what was observed, what was performed and what still needs attention. Below is a blank report structure, not a completed service record.

Observation: Condition, operator report and relevant readings.
Approved work: Tasks actually authorized and carried out.
Result: Functional checks and measurements taken, where applicable.
Open items: Unresolved faults, parts or access still needed.
Next action: Proposed date or usage trigger, with its basis.
Responsibility: Operator care, agreed KONGRA service or specialist work.

Maintenance reduces risk but cannot prevent every failure. Corrective work needs approval; parts and emergency attendance are covered only if quoted. Written findings and invoices are provided; W9 and COI are available on request.

FAQ

Maintenance questions

How often should commercial equipment be serviced?+

The exact model's manufacturer instructions set required tasks and intervals. Operating hours, water condition, kitchen heat and fault history may call for more frequent attention. An interval is extended only where the applicable instructions permit it.

What if a fault returns after a maintenance visit?+

Record when it returns, the operating mode and the message shown. A successful start does not establish a lasting fix for an intermittent fault; the recurrence becomes a follow-up diagnostic item.

Can one agreement cover a mixed kitchen?+

Yes, after a scope review. Refrigeration, dishwashing, ice machines and cooking equipment each need their own model-matched tasks. Parts, corrective repairs and emergency attendance are included only when expressly quoted; there is no default response-time or round-the-clock guarantee.
