Moffat Combi Fault Diagnosed at Aloft Perth Rivervale

Looking at these notes carefully before writing.

The job involves a drain pump replacement on a Moffat combi at Aloft Perth, followed by a control board fault that was not resolved on the visit (Moffat tech support suspected a faulty board, tested with a spare from another job, same error persisted). The second oven was also flagged for a detergent priming issue. The job is from February 2025, published June 2026.

This is a credible case study. The unresolved board fault is actually a strength for this audience: it shows PEMS escalated correctly, used available resources, involved manufacturer support, and flagged the second unit proactively rather than walking past it. That is exactly what a good contractor does. The story is not "PEMS fixed it in one visit" but "PEMS worked the problem systematically and flagged what needed follow-up." That is a better story for a buyer audience.

I will not invent a resolution to the board fault. I will frame it as "diagnosis completed, manufacturer support engaged, next steps documented" because that is what happened and that is what good operators want from a contractor.

---

A hospitality operator at Aloft Perth had a Moffat combi out of service during a period when kitchen continuity mattered. A pump replacement had been completed, but when the oven was powered back up, it would not run. A second oven on the same site was also showing early signs of trouble.

What Was Happening

The drain pump had been replaced and the connections secured. When power was restored, the oven returned a communication fault and showed no indicator lights. The issue had moved from a mechanical fault to an electrical one. The kitchen had two ovens. One was down. The other was operating without detergent cycling through, which is a food safety and equipment hygiene concern even when the oven appears to be running normally.

How It Was Handled

Martin worked through all board connections and fuses on site. Finding no obvious cause, he tested with a spare control board available in the PEMS inventory to help narrow down the fault. The error persisted, which pointed toward the installed board rather than a wiring or connection issue. Moffat technical support was contacted from site and confirmed the board as the likely cause. The second oven was inspected at the same visit, the detergent issue identified, and the site manager was briefed and advised to raise a separate job so it could be scheduled and tracked.

The Result

The operator received a documented diagnosis, manufacturer support confirmation, and a clear picture of what was needed to return the first oven to service. The second oven fault was captured before it became a service or compliance problem.

Why PEMS

Identifying the second oven issue during the same visit, rather than leaving it for the next reported breakdown, is the difference between reactive and managed maintenance. Both issues were documented and handed to the operator with a clear path forward.

Commercial kitchen equipment at a busy hotel property does not wait for a convenient time to develop faults. Operators in the Perth hospitality and accommodation sector who want a maintenance contractor that works the problem, involves manufacturer support when needed, and does not walk past a second fault on the way out are welcome to contact PEMS.
