If your equipment is down right now
Photograph the display code and the mode you were cooking in.
Make sure the water valve to the oven is open and the filter cartridge isn't overdue.
If a descale cycle failed partway, stop and call; restarting can trap chemical in the boiler.

FAQs
Usually scale on the level probes or heating elements, a failed fill valve, or a drain that won't empty. A descale often fixes it, but a burned element has to be replaced.
With untreated Twin Cities water, many kitchens need it monthly or more. Good water filtration stretches that a lot and protects the steam generator.

First visit is card-on-file or COD. Once an account is established, we invoice Net-15 or Net-30 with itemized statements aligned to your accounting cycle.

Every technician holds EPA Section 608 Universal certification covering R-404A, R-448A / R-449A (Solstice N40, Opteon XP40), R-290 hydrocarbon systems where code permits, and legacy R-22. Cooking-equipment techs are gas-certified for natural gas and LP on ranges, fryers, ovens, and combi-ovens.
