5 Tips To Reduce Dishwasher Power Consumption?

Here are some of the best practices that you can follow to reduce dishwasher power consumption.

1. Don’t Overload Your Dishwasher

Every Dishwasher is designed to wash a certain number of dishes per cycle. If you load more dishes than the designed capacity, the machine won’t wash your dishes properly. It will consume more detergent, and most importantly, it will consume more power as it has to do extra work.

2. Choose Air Dry Over Heated Dry

Almost in all dishwashers, you will get two options to dry your dishes. Either you choose the air dry option or use heated dry. Heated dry means, there will be a heater that will dry your dishes.

The downside of heated dry is that it consumes a lot of power. Unless it is required, don’t use the heated dry option. That way, you will save some amount of power.

3. Keep Your Filters Clean

Dishwashers mainly come with two filters. One is a fine filter and the other one is a coarse filter. Any blockage in these filters will delay your wash cycle. That means, the machine has to do more work. More work means more power consumption.

4. Prefer A Cold Wash

Hot wash uses the heater to heat water, which in turn increases the power consumption. A heater is a power-hungry component of any appliance. Unless it is required, I prefer not to use the heater. However, if your dishes are super dirty, you don’t have any option except to use the hot wash option.

5. Service Your Dishwasher Regularly

Servicing your dishwasher regularly is a key factor in determining how many KWh does a dishwasher use per month.

Especially, the filters get bad in no time depending on how dirty dishes you are throwing into the dishwasher.

A dishwasher has multiple sensors like a Turbidity Sensor and a floor Sensor that can easily get damaged if you are not using your dishwasher properly. Regular servicing will ensure that all parts are working as expected. That way, the dishwasher will consume the optimum amount of power.
