Specialist combi oven and combi steamer repair across Perth & WA. Rational, Convotherm, Electrolux Professional and all brands. Electrical and gas. Call 08 7095 3550.
Combi ovens are the most complex and expensive piece of equipment in a commercial kitchen — combining convection heat, steam, and in gas models, a burner system, all controlled by sophisticated electronics. A Rational iCombi Pro or Convotherm is not a job for a general electrician or a plumber. PEMS specialises in exactly this intersection of electrical, gas and mechanical systems — we do not send generalists to combi ovens.
Rational SelfCookingCenter and iCombi Pro repair. Control board faults, steam generator issues, door seal replacement, fan motor faults and software diagnostic resets. Perth's most common combi oven brand.
Convotherm OEB, OES and 4 series combi oven diagnosis and repair. Heating element, steamer, humidity control system and control panel faults.
Electrolux Professional and AOS combi oven repair. Door safety switch, thermostat, element and control board faults across the full range.
Combi oven steam generator repair and descaling. Blocked steam injectors, scale build-up, solenoid valve failure and water inlet issues. Regular descaling is essential in Perth's hard water conditions.
Door seal and gasket replacement for all combi oven brands. A failed door seal causes steam loss, uneven cooking, wasted energy and can trigger safety shutdowns. Usually a same-day repair.
Touchscreen, display panel and main control board repair or replacement. We test under load before recommending full board replacement — sometimes it is a connection or sensor rather than the board itself.
Convection fan motor and impeller replacement. Fan failure causes uneven cooking, temperature error codes and safety shutdowns. Common in high-use kitchens after 3-5 years.
Core temperature probe, oven cavity probe and humidity sensor replacement. Inaccurate probes cause cooking failures and HACCP non-compliance.
Gas burner, gas valve and ignition system repair for gas combi ovens. Requires both gas licence and electrical qualification — PEMS holds both.
Scheduled combi oven maintenance including descaling, gasket inspection, probe calibration and full system check. Extends equipment life and reduces breakdown frequency significantly.
We have access to service documentation for all major combi brands. Most error codes point to a specific sensor, board or component rather than a complete failure. We diagnose before ordering parts.
Most common cause in Perth is scale build-up on the steam generator from hard water. Secondary causes are solenoid valve failure or water inlet restriction. A descale and inspection resolves the majority of steam faults.
Fan motor beginning to fail, temperature probe drift or door seal leak causing heat loss. A combi oven producing inconsistent results is costing you food quality and waste — don't wait until it stops completely.
Door gasket failure. The gasket is a wear item that degrades with heat cycles. Replacement is straightforward and inexpensive relative to the running cost of a leaking oven.
Element failure (electric), burner fault (gas), temperature probe drift or fan motor slowing. Each has a different repair path — systematic diagnosis is essential.
Rational, Convotherm, Electrolux Professional, Hobart, Giorik, Lainox, Unox, Turbofan, Moffat and all other commercial combi oven brands across Perth and WA.
Most repairs are completed same day or next day. Complex control board or steam generator issues may take 2-3 days depending on parts availability. We will always give you an honest timeline upfront.
In most cases, repair is significantly cheaper than replacement. A Rational or Convotherm is a $15,000-$40,000 piece of equipment. We will give you an honest assessment of whether repair is economical before proceeding — we won't recommend a repair that doesn't make financial sense.
We carry common parts for Rational and Convotherm — door gaskets, temperature probes, steam generator components and fan motors. For less common parts we source quickly through our supplier network, often same day.
Perth has hard water with high mineral content. This causes accelerated scale build-up in steam generators. Regular descaling (every 3-6 months depending on usage) is essential — neglected scale build-up causes steam generator failure which is an expensive repair.
All Perth metro suburbs from Yanchep to Mandurah. Regional WA by arrangement. Most Perth metro jobs attended same day or next day.
