Combi Oven Fault Diagnosed and Fixed in Mandurah Cafe Kitchen

A community recreation centre in Mandurah runs a cafe kitchen as part of its daily public operations. When the combi oven in that kitchen started throwing an air filter fault, the facilities team did what most would do. They cleaned the filter and waited to see if the problem cleared.

What Was Happening

The fault kept returning after the filter was cleaned. What looked like a maintenance issue turned out to be something else entirely. A failed internal cooling fan was the root cause. Without that fan running, the oven could not manage its own internal temperatures, and the fault message was the oven's way of flagging it. The filter was in poor condition and needed replacing regardless, but cleaning it was never going to fix the underlying problem.

How It Was Handled

PEMS attended the site and tested the unit properly rather than treating the fault message at face value. The failed power supply driving the cooling fan was identified and replaced. A replacement air filter was also specified as a follow-on action. The oven was returned to full operation with both the immediate fault and the contributing condition documented in the service record.

The Result

The combi was back in service the same day. The operator received a complete service record covering what was found, what was replaced, and what requires follow-up. Nothing was left open without documentation.

Why PEMS

This site had a prior PEMS service history. That context mattered. Knowing the unit's background meant the technician could move faster and with more confidence toward the real cause, rather than starting from scratch.
