Frequently Asked Questions
My dishwasher isn't dispensing chemicals properly. What's wrong?
Chemical dispensing problems are typically caused by: clogged or faulty chemical pumps, incorrect dilution ratios, empty chemical containers, broken injection lines, or control board issues. In low-temperature machines, proper chemical concentration is essential for sanitization — test strips should verify concentration after every repair. Many chemical distributors offer free testing; alternatively, a technician can verify and repair the dispensing system.
How do I know if my commercial refrigeration has a refrigerant leak?
Signs of a refrigerant leak: unit runs but doesn't reach temperature, ice buildup on evaporator coil, hissing or bubbling sounds from refrigerant lines, oily residue near connections or fittings, and higher than normal electricity consumption. Only EPA-certified technicians can legally handle refrigerant. If you suspect a leak, call a technician promptly — operating a refrigerator with low refrigerant damages the compressor.
Why has my ice machine's production dropped?
Reduced ice production is usually caused by: mineral scale buildup on evaporator plates reducing heat transfer, dirty condenser coils reducing refrigeration efficiency, warm ambient temperature in the equipment room, low refrigerant levels, or water flow problems. The fix for scale buildup is professional cleaning and descaling. Other issues require a technician. Never ignore reduced production — it often progresses to complete failure.
