Commercial Dishwasher Fault Diagnosed at The Residence Perth

A commercial dishwasher at The Residence Perth (Regency Hyatt) on Adelaide Terrace, Perth CBD, developed a persistent fault in April 2026. With a high-volume hospitality operation running daily service across multiple dining outlets, a non-functional dishwasher threatened both hygiene compliance and kitchen workflow.

The Fault

The machine displayed error codes 1 and 2, pointing to a heating and filling fault. PEMS technician Tore ran systematic resistance tests across all heating elements, which returned within spec. Contactors and the float switch were also tested and confirmed operational. Further investigation identified the true culprit: the fill solenoids were not passing water during the fill cycle despite receiving the correct signal.

The Repair

Tore isolated the faulty solenoids and moved immediately to source replacement parts. Hobart confirmed no stock was available locally, with a two-week lead time on supply. PEMS documented all findings thoroughly, reported the parts delay directly to the client, and prepared the job for fast completion as soon as components arrive. Interim operational advice was provided to the kitchen team.

The Outcome

The root cause was accurately diagnosed and confirmed, preventing unnecessary component replacements. The kitchen team now has a clear timeline and a documented repair plan, avoiding guesswork and further downtime costs.

Why PEMS

PEMS works systematically through every possible fault point before reaching a conclusion. At The Residence Perth, that process saved time and money by ruling out expensive component changes and identifying exactly what needed replacing.
