Calibration cycles in washing machine appliances

A method for a fill cycle calibration in a washing machine appliance, the washing machine comprising a tub, a basket within the tub, and a controller, the method comprising:

• receiving, at a controller, an activation signal of a calibration cycle,
• performing the calibration cycle in response to receiving the activation signal, the calibration cycle comprising:
• initializing, by the controller, a fill sequence of the washing machine appliance;
• determining, by the controller, a supply connection orientation of a hot water supply hose and a cold water supply hose;
• measuring, by the controller, a volume of water from a hot water supply valve before reaching a predetermined temperature threshold;
• measuring, by the controller, flow rates of water from the hot water supply valve and a cold water supply valve;
• and
• updating, by the controller, operational parameters of the washing machine appliance in response to each of the supply connection orientation, the volume of water from the hot water supply valve before reaching the predetermined temperature threshold, and flow rates of water from the hot water supply valve and the cold water supply valve,
• analyzing, by the controller, a cycle history of the washing machine appliance, wherein the cycle history indicates a cycle was conducted within a set time of receiving the activation signal of the calibration cycle, the method further comprising:
• determining, by the controller, a distorted temperature reading based on the cycle conducted within the set time of receiving the activation signal;
• and
• updating, by the controller, the operational parameters is in response to each of the supply connection orientation and flow rates of water from the hot water supply valve and the cold water supply valve.
