Question 1

What is the real difference between a commercial and a residential dishwasher?

Accepted Answer

The key differences are speed, hygiene, and power. A commercial machine washes and sanitizes within 1 minute at 82°C (180°F), while a home model takes over an hour and does not get hot enough to sanitize. We explain this in detail in our guide, Commercial vs. Residential Dishwasher: Can You Use One at Home?

Question 2

What do I need for installation?

Accepted Answer

This is a critical step. You need to confirm your power supply (single-phase or 3-phase), hot water access, and floor drainage. A high-temp model may also need a ventilation hood. We cover all of this in our Commercial Dishwasher Installation: A Pre-Installation Checklist.

Question 3

What is the running cost of a commercial dishwasher?

Accepted Answer

Costs include water, electricity, and chemicals. Modern high-efficiency models can save you thousands. For example, units with heat recovery reuse steam to heat incoming water, slashing electricity use.

Question 4

What is a "high-temp" vs. "low-temp" machine?

Accepted Answer

• High-Temp machines are the standard. They use a booster heater to rinse at 82°C+, killing bacteria with heat. (Source: https://www.fsai.ie/food-business/food-safety-management-system/dishwashing-in-food-businesses).
 • Low-Temp machines use chemical sanitizers (like chlorine) to kill bacteria. They are cheaper to run but require the ongoing purchase of sanitizer chemicals. Our Commercial Dishwasher Chemicals & Rinse Aids Explained guide covers this.

Question 5

How often do these machines need maintenance?

Accepted Answer

Daily cleaning of filters by your staff is essential. We recommend regular professional servicing to keep your machine in peak condition. Our complete Commercial Dishwasher Maintenance & Troubleshooting (A Complete Owner's Guide) provides a full schedule.
