Required maintenance follows the exact model and revision. Merrychef conneX and e2s routines differ; Rational checklists also apply to specified models and markets. 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.

Commercial dishwasher diagnostics
A KONGRA job photograph shows the rack oven door and hinge area with the outer trim removed. Door support, hinge movement and closing alignment are assessed together; this access view is not a post-repair test 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 findingsAn 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.

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.
Record equipment identity, available backup, symptoms, task sources, service windows and handover. Keep completed copies with your private equipment records.
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.
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.
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.
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.
