5 Tips To Reduce Dishwasher Power Consumption?
Here are some best practices 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 them properly.
It will consume more detergent and, most importantly, more power as it has to do extra work.
2. Choose Air Dry Over Heated Dry
You will get two options to dry your dishes in almost all dishwashers. You can choose either the air-dry option or the heated dry option. A heated dryer means there will be a heater that will dry your dishes.
The downside of heated drying is that it consumes a lot of power. Don’t use the heated dry option unless it is required. That way, you will save some power.
3. Keep Your Filters Clean
Dishwashers mainly have two filters: a fine filter and a coarse filter. Any blockage in these filters will delay your wash cycle, which means the machine has to do more work, which 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 a dishwasher uses monthly.
Especially, the filters get bad in no time depending on how dirty dishes you throw into the dishwasher.
A dishwasher has multiple sensors, such as a Turbidity Sensor and a Flood Sensor, that can easily get damaged if not used properly.
Regular servicing will ensure that all parts work as expected, allowing the dishwasher to consume the optimum power.

Knowing about a particular appliance before you buy it is always wise. After purchasing, you have no other option except to regret it.
