Combi Oven Drain Fault Repair Stirling Perth | PEMS

Opening paragraph:

A Convotherm combi oven at a major supermarket in Stirling was leaking during a live chicken roasting cycle. Water was finding its way into the electrical components. The oven was in use when the fault was identified. Keeping it running was not an option.

What Was Happening

The oven's drain had blocked completely. With nowhere to go, water backed up and began escaping through the door and into the wiring. The electrical system was compromised. A blocked drain on a combi running daily roasting cycles is not a slow-burn fault. It puts the unit out of service immediately and introduces a safety concern that cannot be worked around.

How It Was Handled

The technician attended after hours and spent several hours clearing the drain, stripping out the affected components, cleaning the drain box, replacing both the drain pump and circulation pump, and rewiring the entire wiring harness. Everything was tested before the site was left. The deli manager was briefed throughout. One attendance, one documented outcome. The site's facilities team had the full scope on record before the next trading day.

The Result

The oven was returned to service fully operational. All replaced components were documented. The operator had a clear record of what was found, what was replaced, and what follow-up was flagged for scope. No ambiguity on the invoice, no open questions at handover.

Why PEMS

Multi-trade capability meant the electrical and mechanical work was handled in a single attendance, not split across two contractors and two callouts. For a site running a live food service operation, that distinction matters directly to downtime and cost.
