In a commercial kitchen, every minute counts. The dishwasher is a key component for maintaining a smooth workflow, ensuring hygiene, and optimizing resources. However, when choosing a dishwasher, a common question arises:
Dishwasher with or without a drain pump?
The answer depends on your installation, the type of drain, and the location of the equipment. Here's the definitive guide to getting it right the first time.
Difference between dishwashers with and without a drain pump
The key is how the dirty water is evacuated :
-
Without pump (gravity evacuation) :
The water flows under its own weight toward the drain. It's cheaper, simpler, and less likely to break, but it requires the drain to be below the dishwasher outlet. -
With pump :
It includes a motor that propels water upward, allowing the unit to be installed even if the drain is at the same level or above it. It provides flexibility in kitchens with limited space.
When to choose each option?
-
✅ Without pump : Ideal if the drain is low and you can raise the dishwasher about 25 cm so that the water flows effortlessly.
-
✅ With pump : Perfect if the drain is high, if the equipment is on a counter, or if you cannot modify the installation height.
Advantages and disadvantages
| Guy | Advantages | Disadvantages |
|---|---|---|
| No pump (gravity) | Cheaper, fewer breakdowns, easy installation | Requires height and low drainage |
| With pump | Flexible in location, installation at any point | More expensive, requires periodic maintenance |
Tips before installing
-
Please measure the height of the drain before purchasing.
-
Assess the installation : elevating the equipment can save you the cost of the pump.
-
Plan your maintenance : If you choose a pump, clean the filters regularly to avoid blockages.
-
Consult a technician if you have any questions: this will save you from unexpected problems and expenses.
Maintenance and useful life
-
Clean the filters daily.
-
Avoid solid waste in the tank.
-
Perform preventative maintenance every 6 months to check the pump and connections.
Conclusion
If gravity is on your side, a pumpless dishwasher will be more economical and easier to maintain.
If not, invest in a model with a pump: you'll gain flexibility, comfort, and avoid unpleasant surprises.
Pro tip: A bad drain not only slows down your wash cycle, it can also cause odors and hygiene problems. Choosing the right drain starts before you even turn on your dishwasher.
