Common Commercial Dishwasher Problems

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.

Repair vs. Replacement - Commercial Dishwashers

Commercial dishwashers run dozens of cycles daily. Most failures are repairable.

  • Unit under 8 years old (Repair): Commercial dishwashers last 10–15 years. Component repairs keep them running through heavy use.
  • Pump or heating element (Repair): Pump and heater repairs (from $350) restore wash performance. Far less than a $4,000+ replacement.
  • Sanitizing temp not reached (Repair): Booster heater or thermostat repair restores the required 180°F final rinse at a fraction of replacement cost.
  • Multiple major failures (Replace): When pump, heater, and controls all fail on an aging unit, a new energy-efficient machine often saves more long-term.

How We Diagnose and Fix Commercial Dishwashers

1. 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.

2. Parts & Written Quote

You approve a written flat-rate quote before we touch the machine. Common parts arrive in 2-4 business days; specialty components take longer, and we quote the lead time before you approve.

3. Repair & Verification

After repair, we run a complete wash cycle, verify sanitization temperature reaches 180°F, check for leaks, and confirm proper drain function. 180-day warranty.

Frequently Asked Questions

Who repairs commercial dishwashers in San Francisco?

FixitBay LLC services commercial dishwashers across San Francisco, the Peninsula and Marin, from high-temp and low-temp machines to under-counter and conveyor units in restaurant kitchens. We are a licensed California appliance technician (BHGS #51001). A commercial call is a $100 diagnostic credited toward the repair, a written estimate before anything is ordered, and a 180-day warranty on parts and labor. Most dishwashers wash clean again on the first visit; if a model-specific part is needed, it arrives in a few business days and you get the price before you approve. Book same-day or next-day and pick the earliest open window.

Do you repair all types of commercial dishwashers?

Yes. We service under-counter dishwashers, single and double-rack door-type machines, conveyor dishwashers, flight-type machines, and glasswashers. We work with restaurants, hotels, hospitals, schools, and catering operations throughout San Francisco, the Peninsula, and Marin County.

How fast can you respond?

We prioritize commercial dish machines for same- or next-day service. A dead dishwasher backs up a kitchen fast, so we route these calls to the first available slot, and the online booking calendar always shows the earliest window. We also schedule around your service - early morning before you open, evening after close, or weekends - to keep the disruption off your busiest hours. Every job starts with a $100 diagnostic (credited toward the repair) and a written flat-rate quote you approve before any work begins.

What is the difference between high-temp and low-temp commercial dishwashers?

High-temp machines sanitize with 180°F+ water in the final rinse. Low-temp machines sanitize using chemical solution (typically chlorine or quaternary ammonium) at lower water temperatures. We repair both types. High-temp machines are more common in San Francisco restaurants due to better sanitization results.

What commercial dishwasher brands do you repair?

We repair Hobart, Champion, Jackson, Electrolux Professional, CMA Dishmachines, Winterhalter, Ecolab, Stero, Noble Warewashing, and all other major commercial warewashing brands.

How much does commercial dishwasher repair cost?

To give you an exact commercial dishwasher repair cost, we need to perform a diagnostic first. The diagnostic fee is $100. After the diagnostic, we'll provide you with a written repair estimate. Once you approve and go ahead with the repair, the $100 is included in the total cost of the work. We also provide a 180-day warranty on parts and labor.

Is there a warranty on commercial dishwasher repairs?

Yes. All commercial dishwasher repairs include our 180-day warranty on parts and labor.

Do you offer maintenance plans for commercial dishwashers?

Yes. For high-use dish machines we offer maintenance visits alongside one-off repairs. Routine service covers the failure points we see most: booster heaters and thermostats drifting out of the 180°F sanitizing range, spray arms and wash jets clogging, drain screens and pumps fouling, and door gaskets wearing from thousands of daily cycles. Catching these before they fail keeps the machine off a mid-service breakdown, and every visit is documented and carries the same 180-day warranty on the parts we service.

Do you provide invoices and documentation for business records?

Yes. Every commercial dishwasher repair comes with an itemized invoice - work performed, parts used, the flat-rate charge, and warranty coverage - ready for your bookkeeper and your records. We bill per job, not by the hour, so the price you approve is the price you pay. Invoices and service documentation for expense tracking or compliance files are provided on request.

What payment methods do you accept?

We accept all major credit and debit cards (Visa, Mastercard, American Express, Discover), Apple Pay, Venmo, Zelle, online payment via secure invoice link, business checks, and cash. Payment is collected after the repair is complete and you've approved the work. We don't require a deposit beyond the $100 commercial diagnostic visit fee, which is fully credited toward your repair if you proceed. Invoices and documentation for business records provided on request.
