Hobart Dishwasher Repair

A Hobart that stops sanitizing can stop a kitchen. In Tampa restaurants, bars and cafeterias, most Hobart warewashers are undercounter units or door-type machines, with conveyor models in high-volume operations. All of them wash with heated water recirculated from a tank through spinning arms, then finish each rack with a fresh final rinse that sanitizes either with heat or with a chemical.

Which method your machine uses decides the diagnosis. A high-temperature machine depends on a booster heater to lift the final rinse to sanitizing temperature, plus a heated wash tank. When dishes come out cool and spotty, we look at the booster element, its thermostat and its contactor. On a low-temperature chemical machine, the same complaint may be a dispenser or supply issue for your chemical vendor.

Scale is the booster's main enemy. Minerals in the incoming water coat the element and insulate it until it overheats and fails, and the same deposits narrow rinse nozzles. Many Tampa kitchens see noticeable scale, so a regular deliming routine matters. Other wear comes from sheer volume: door interlock switches wear out and stop cycles midway, and fill solenoids stick and short-fill the tank.

Pump seals eventually weep onto the dish room floor, and food that gets past the scrap screens plugs wash arm nozzles. Before calling, shut the machine down at its disconnect, empty and clean the scrap screens and baskets, remove and flush the wash and rinse arms, and confirm the water valve is open and the booster breaker has not tripped. Never bypass a door switch or temperature lockout.

On site we measure wash tank and final-rinse temperatures during a live cycle, check fill volume and timing, and watch the drain, then test the elements, thermostats, contactors, solenoids, interlocks and pump those readings point to. Hobart machines are built to be maintained for years, so part repairs nearly always make sense; a cracked tank or badly corroded frame is where replacement comes up.
