Common Commercial Dishwasher Problems
A dead dish machine backs up a kitchen within one service. San Francisco health code requires every food-contact surface to be sanitized, so a dishwasher that can't reach temperature puts you out of compliance until it's fixed. FixitBay LLC repairs commercial dishwashers for restaurants, hotels, hospitals, and institutional kitchens across San Francisco, the Peninsula, and Marin County.
Our licensed technician diagnoses under-counter units, door-type machines, and conveyor dishwashers from all major manufacturers. We test wash and rinse temperatures, inspect spray arms and pumps, check chemical dispensers, and evaluate control systems. The $100 diagnostic fee is credited toward your repair.
We rebuild wash and drain pumps, replace booster heaters and heating elements, recalibrate thermostats, and repair control boards. Every repair carries our 180-day warranty on parts and labor.
Not Cleaning Dishes Properly
Commercial dishwasher leaving food residue, spots, or film on dishes due to spray arm clogs, detergent dispenser malfunction, or insufficient water temperature in high-volume restaurant service.
Not Draining or Slow Drainage
Water pooling in the wash chamber after cycle completion. Typically caused by clogged drain screens, failed drain pumps, or blocked drain lines from food debris accumulation.
Not Reaching Sanitizing Temperature
High-temp units failing to reach the 180°F rinse temperature required by San Francisco health code. Booster heater failure, thermostat drift, or heating element issues are common culprits.
Leaking Water on Kitchen Floor
Door gaskets deteriorating from heat cycles, pump seal failures, or loose plumbing connections causing water on the floor, a slip hazard your staff works around all shift.
Won't Start or Complete Cycle
Door interlock switch failures, control board malfunctions, or timer relay problems preventing the dishwasher from initiating or finishing wash and rinse cycles.
Chemical Dispenser Not Working
Detergent and rinse aid dispensers clogged, pumps failing, or chemical lines kinked - resulting in poor wash quality and sanitization concerns.
Conveyor Drive Belt Issues
Conveyor-type dishwashers with belt slipping, tearing, or motor failures causing racks to stop moving through the machine.
Wash or Rinse Below the Required Temperature
Wash water under 150°F, or a final rinse under the 180°F high-temp sanitizing point (or weak sanitizer on a low-temp machine). We measure at the dish surface, find why it is running cold, and bring it back into range.
What Types of Commercial Dishwashers Do We Repair?
A wine bar runs a compact under-counter glasswasher; a hotel banquet kitchen runs a conveyor line that clears 300 racks an hour. We repair every type on this page, and each one fails in its own way, so we bring the right parts and test gear for the machine you actually run.
Under-Counter Dishwashers
Compact units used in bars, cafes, and small restaurants. Common issues include pump failures, heating element burnout, and door latch problems. Brands: Hobart LXe, Jackson DishStar, Champion UH-series.
Door-Type (Single Rack)
The workhorse of most San Francisco restaurants. Single-rack machines process 30-60 racks per hour. We repair high-temp and low-temp variants. Brands: Hobart AM-series, Champion 44, Jackson Avenger.
Conveyor Dishwashers
High-volume machines for hotels, hospitals, and large catering operations. Belt-driven systems that process 150-300+ racks per hour. We service the drive motor, belt, wash pumps, and temperature controls. Brands: Hobart FT-series, Champion 80, Electrolux Professional.
Glasswashers
Specialized low-profile machines for bars and tasting rooms. Gentle wash action to prevent breakage. Common issues: pump pressure loss, rinse temperature, and chemical dispenser failures.
What Does San Francisco Health Code Require From a Dish Machine?
The San Francisco Department of Public Health sets the warewashing standards your kitchen is inspected against: a minimum wash and final-rinse temperature for high-temp machines, and a minimum sanitizer concentration for low-temp. When a dish machine drifts below those numbers, we recalibrate and repair it back into range so it passes.
High-Temp Sanitizing: Final rinse must reach 180°F (82°C) minimum
We test booster heaters, calibrate thermostats, replace heating elements, and verify rinse temperature at the dish surface - not just the tank.
Low-Temp Sanitizing: Chemical concentration must meet EPA standards
We repair chemical dispensers, calibrate dilution pumps, check supply lines, and test sanitizer concentration with certified test strips.
Wash Temperature: Minimum 150°F (65°C) for wash cycle
We verify incoming water temperature, check tank heaters, inspect mixing valves, and ensure proper wash cycle duration.
Repair vs. Replacement - Commercial Dishwashers
Commercial dishwashers run dozens of cycles daily. Most failures are repairable.
Commercial dishwashers last 10–15 years. Component repairs keep them running through heavy use.
Pump and heater repairs (from $350) restore wash performance. Far less than a $4,000+ replacement.
Booster heater or thermostat repair restores the required 180°F final rinse at a fraction of replacement cost.
When pump, heater, and controls all fail on an aging unit, a new energy-efficient machine often saves more long-term.
Our honest policy: If our diagnostic shows the repair isn't economically justified - we'll tell you before any work begins. No pressure, no hidden charges beyond the $100 diagnostic fee.
How We Diagnose and Fix Commercial Dishwashers
Commercial Diagnostic
We test the wash pump, drain pump, heating element, booster heater, fill valve, door latch, and control board. Water temperature is measured at wash and rinse stages.
