01, About This Service
A commercial dishwasher that isn't sanitizing isn't just inconvenient, it's a health code violation in progress.
Most operators think of commercial dishwasher failure in terms of clean vs. dirty dishes. But the real standard across SoCal county health authorities (LA County DPH, OC Health Care Agency, Ventura County Environmental Health, San Bernardino DEHS, Riverside County DEH, all enforcing CalCode) isn't "clean", it's sanitized. A commercial dishwasher is required to reach 140°F for chemical sanitizing machines or 180°F on the final rinse for high-temperature machines. A machine that's washing dishes but not hitting these temperatures is producing sanitized-looking dishes that may carry bacterial contamination, and failing health inspection if an inspector runs a temperature check during a routine visit.
The second issue specific to LA is hard water. At 300–400 mg/L total dissolved solids, LA water deposits mineral scale inside spray arm holes, on heating elements, and on glassware during the drying cycle. Bars and restaurants lose the professional presentation of their glassware when scale builds unchecked, cloudy wine glasses or spotted pint glasses are a direct consequence of a dishwasher that isn't maintaining proper rinse aid dosing and descaling intervals.
We service all major commercial dishwasher types and brands, with Jackson parts carried specifically on service vehicles. All repairs include a temperature verification to confirm the machine is meeting sanitizing spec before we leave.
If your commercial dishwasher is not reaching 140°F (chemical sanitize) or 180°F (high-temp final rinse), stop relying on it for sanitizing and call (424) 325-0520 immediately. This is a county health-code violation waiting to be discovered. We treat sanitizing temperature failures as priority same-day calls, the health code risk makes it one.
02, Sanitizing Temperature & Health Code
The temperature your dishwasher must reach, and what happens when it doesn't
SoCal county health-authority regulations (CalCode-based) specify minimum temperatures for commercial dishwashers. "Looks clean" is not the standard, measured temperature is.
Two types of commercial dishwashers, two temperature standards
California's CalCode (Title 17/22, adopted by all SoCal county health departments) follows FDA Food Code guidelines for warewashing equipment. There are two compliant sanitizing methods, chemical and high-temperature. Whichever type your machine is, it must consistently reach its required temperature to be in compliance with LADPH, OC HCA, Ventura, SB DEHS, or Riverside DEH inspection.
140°F Wash Temperature
Chemical sanitizing machines use chlorine, iodine, or quaternary ammonium at cool-to-warm temperatures. The chemical does the sanitizing work, but the wash temperature must still reach 140°F to properly clean before chemical contact. If the machine isn't heating adequately, chemical sanitizing effectiveness is compromised.
180°F Final Rinse
High-temperature machines use hot water itself to sanitize, no chemicals required. The final rinse must reach 180°F at the dish surface. A heating element failure, thermostat drift, or booster heater failure can drop final rinse temperature below this threshold while the machine continues to operate normally in every other way.
We verify final rinse temperature against a calibrated thermometer on every commercial dishwasher service call, and provide written documentation of the reading for your health inspection records.

04, Common Failures
What our technicians diagnose most often in SoCal commercial dishwashers
Not Cleaning Properly / Food Residue
In LA specifically, scale-clogged spray arm holes are the most common cause, mineral deposits from hard water progressively block the small holes in spray arms, reducing water pressure and distribution. Also: failed wash pump motor reducing overall pressure, or detergent dispenser failure leaving dishes with inadequate chemical contact time. We descale spray arms before recommending part replacement.
Not Reaching Sanitizing Temperature
The health code failure mode. For high-temp machines: failed heating element or booster heater, thermostat drift, or scale buildup on the heating element insulating it from the water. For low-temp chemical machines: failed heating element dropping wash temperature below effective cleaning range. We calibrate against a reference thermometer and provide written temperature documentation.
Not Draining
Failed drain pump motor (most common), blocked drain line with food debris, or a faulty drain solenoid. Water pooling in the wash tank after cycle is a health hazard, bacteria accumulate in standing water that then contacts clean dishes on the next cycle. We treat drainage failures as health code priority calls.
Leaking
Door gasket compression failure (water leaking from door edges), overfill from a faulty water inlet valve, or a damaged pump seal. Any water on a commercial kitchen floor is both a slip hazard and a health inspection issue. Turn off the machine and call us, we typically diagnose and repair same day.
Cloudy Glasses / Spotted Dishes
LA hard water mineral deposits on glassware during the drying cycle. Root cause: rinse aid dispenser failure (rinse aid prevents scale adhesion), or a water softener/treatment system that needs servicing. We check and calibrate chemical dispensers on every call, proper rinse aid dosing is the primary defense against scale on glassware.
Chemical Dispenser Failure
Commercial dishwashers use automatic dispensers for detergent and rinse aid. When a dispenser fails, clogged injector, failed pump, or empty supply not triggering an alarm, dishes may appear washed but lack proper chemical treatment. Dispenser failure also affects sanitizing compliance on low-temp machines.
300–400 mg/L TDS, why LA dishwashers need more frequent descaling
SoCal water's high mineral content (300–400+ mg/L TDS across all 5 counties; Inland Empire wells often run higher) deposits scale inside spray arm holes, on heating elements, on the interior wash tank, and on glassware during drying. For a machine running 200+ rack cycles per day, this accumulation is measurable within weeks. Scale inside spray arms reduces hole diameter and water pressure, the machine cycles normally but can't deliver adequate cleaning force. Scale on heating elements insulates them and reduces heating efficiency, pushing the machine toward temperature non-compliance. Descaling every 3–4 months is the practical standard across SoCal for high-volume operations, not the 6-month schedule designed for lower-hardness water supplies.
05, Jackson Commercial Dishwashers
The most common commercial dishwasher brand across SoCal, and why we stock Jackson parts on the van
Jackson WWS and Conserver series run most SoCal restaurant dish lines
Jackson Commercial Products is the dominant brand across SoCal's independent restaurant market, affordable, reliable, and with a parts availability network that makes them practical for commercial kitchens. The Jackson WWS series door-type machines and Conserver undercounter units are the models we see on service calls more than any other commercial dishwasher brand.
Common Jackson failure patterns across SoCal: wash pump impeller scale buildup from regional hard water (the impeller collects scale that reduces flow without triggering an obvious error), door latch wear on high-volume operations (the door latch assembly on Jackson door-type machines is a consumable part in heavy use), and heating element scale coating that reduces high-temp final rinse performance below 180°F spec.
We carry Jackson wash pump motors, door latch assemblies, heating elements, spray arm assemblies, and door gaskets on service vehicles specifically because these are the most common same-day repair needs on Jackson equipment across SoCal.

07, Recent Repairs
What our technicians actually fixed recently
"Dishes coming out with food still on them, spray pressure seems low"
Scale-clogged spray arms on a Jackson WWS-30S door-type machine, the upper and lower spray arm holes had accumulated significant mineral scale from LA hard water, reducing effective spray coverage by roughly 40%. The machine was cycling at the correct temperature and pressure at the pump, but the restricted holes meant water wasn't reaching the dishes adequately. Classic LA presentation that's easily confused with pump failure.
"Wine glasses coming out spotted and cloudy, customers complaining"
Failed rinse aid dispenser on a Hobart LXEH glasswasher, the dispenser pump had seized, stopping rinse aid injection during the final rinse. Without rinse aid, OC coastal hard water was depositing mineral scale on every glass during drying. The machine was otherwise functioning correctly, it was the absence of rinse aid that was causing the visual issue. The bar had been running this way for approximately 3 weeks before the glass quality became customer-visible.
"Health inspector cited us, final rinse temperature only 168°F"
Booster heater failure on a Champion high-temperature dishwasher, the booster heater raises incoming water temperature to meet the 180°F final rinse requirement. When the booster heater element failed, the machine was still washing and rinsing but the final rinse was only reaching the incoming hot water temperature (approximately 140–160°F from the building's water heater), not the 180°F required for high-temp sanitizing. The restaurant received a Ventura County Environmental Health code violation and a 30-day correction period.
"Machine not draining, water overflowing the wash tank onto the floor"
Failed drain solenoid valve on a Jackson TempStar conveyor dishwasher, the solenoid that opens the drain at the end of each cycle had failed in the closed position, preventing drainage. The wash tank filled to capacity and began overflowing. In a hotel kitchen running continuous covers, this was an immediate shutdown, standing water on a commercial kitchen floor with a health inspection pending the following week.

09, Frequently Asked Questions
Commercial dishwasher repair, what SoCal operators ask us
How much does commercial dishwasher repair cost?
Commercial diagnostic is $120, applied to the repair if approved. Most repairs run $180–$500. Wash pump, spray arm, door latch, heating element, or drain pump is toward the lower end. Booster heater or control board runs higher. Written estimate before any work begins.
Which areas of Southern California do you cover?
All five SoCal counties: Los Angeles, Orange, Ventura, San Bernardino, and Riverside. We dispatch from 8 service territories so the technician on your commercial call is coming from the closest one. Same-day commercial priority dispatch across all 5 counties.
My commercial dishwasher is not reaching sanitizing temperature, is this a health code issue?
Yes. CalCode requires 140°F for chemical sanitize machines and 180°F final rinse for high-temp machines, enforced by all SoCal county health authorities (LA County DPH, OC HCA, Ventura, SB DEHS, Riverside DEH). A machine not hitting spec is a health code violation. Stop relying on it for sanitizing and call us at (424) 325-0520, we treat this as a priority same-day call. We verify and document final rinse temperature on every service call.
My commercial dishwasher is not cleaning dishes properly, what causes that?
Across SoCal, scale-clogged spray arm holes from hard water are the most common cause. Also: failed wash pump motor, depleted chemical dispenser, or temperature below spec. We descale spray arms and check all four factors before recommending part replacement, often cleaning alone restores performance.
Why are my glasses coming out cloudy?
Mineral scale from SoCal's hard water depositing on glass during drying, almost always caused by a failed rinse aid dispenser or inadequate rinse aid dosing. We check and calibrate chemical dispensers on every call. A water softener on the incoming line is the long-term solution for premium glassware quality.
Do you repair Jackson commercial dishwashers?
Yes. Jackson is the most common commercial dishwasher brand across SoCal restaurants. We carry Jackson wash pump motors, door latch assemblies, heating elements, spray arm assemblies, and door gaskets on the van. Jackson WWS series and Conserver units are our most frequent service calls.
My commercial dishwasher is leaking, what should I do?
Turn off the machine and stop using it, water on a commercial kitchen floor is a slip hazard and a health inspection issue. Common causes: door gasket failure, faulty water inlet valve, or damaged pump seal. We diagnose and repair same day in most cases. Document the leak location if you can, it helps us bring the right parts.
How often should a commercial dishwasher be serviced?
Every 3–4 months for high-volume operations across SoCal, every 6 months minimum for all commercial machines. SoCal water's hardness accelerates scale buildup on spray arms and heating elements faster than most manufacturer schedules assume. Each service includes temperature calibration and written documentation for health inspection records.
When does it make sense to repair vs replace a commercial dishwasher?
Commercial dishwashers (Jackson, Hobart, Champion) are built for 12-15 year service lives with proper maintenance. Repair almost always makes sense unless the wash tank is corroded through (typically only on units 15+ years old that haven't been descaled regularly). Replacement runs $5,000–$25,000+ for a new unit plus installation, plumbing, and electrical.
