Motor detection methodology and system

A washing appliance, the appliance comprising:

• a cabinet defining a wash chamber for receipt of articles for washing;
• a spray arm disposed within the wash chamber;
• a first motor associated with a circulation wash pump assembly of the washing appliance;
• a second motor associated with a drain pump assembly of the washing appliance;
• a relay configured to be adjusted between at least a first position associated with a first circuit of the first motor and a second position associated with a second circuit of the second motor;
• and
• one or more control devices configured to identify the position of the relay within the appliance by executing computer-readable instructions stored in one or more memory devices that when executed by the one or more control devices cause the one or more control devices to perform operations, the operations comprising:
• providing a test signal to the relay;
• detecting an output signal that is based on the test signal, wherein the output signal is associated with the second circuit;
• determining the relay is in the first position when the output signal corresponds to a first reference signal indicative of the relay being in the first position;
• and
• determining the relay is in the second position when the output signal corresponds to a second reference signal indicative of the relay being in the second position.
