It is not recommended to rinse a dishwasher with hot water. Dishwashers are designed to handle the hot water needed for their cleaning cycles, and rinsing them with hot water can actually be detrimental to their functionality and potentially cause damage.
Dishwashers have internal heating elements that heat the water to the appropriate temperature for effective cleaning and sanitization. When you rinse the dishwasher with hot water externally, it can lead to overheating, which might affect the dishwasher's components, such as the plastic parts or seals.
If you're experiencing issues with your dishwasher's cleaning performance, it's best to consult the user manual for troubleshooting tips or seek assistance from a professional appliance repair service. Additionally, make sure to use the appropriate dishwasher detergent and load the dishes correctly to achieve the best cleaning results.
