Abstract
A control circuit for a washing machine appliance is provided. The control circuit includes a ground detection circuit configured to receive a test signal from a test ground path. The control circuit further includes a controller configured to determine a grounding state of a subwasher of the washing machine appliance based at least in part on the test signal. The test ground path operatively couples the ground detection circuit to the subwasher.
Claims20
A control circuit for a washing machine appliance, comprising:
- a ground detection circuit configured to receive a test signal from a main ground path via a test ground path;
- and
- a controller configured to determine a grounding state of a subwasher of the washing machine appliance based at least in part on the test signal;
- and
- wherein the test ground path operatively couples the ground detection circuit to the subwasher.
A method for determining a grounding state of a subwasher, disposed between a main ground path and a test ground path, in a washing machine appliance, the method comprising:
- receiving, by a ground detection circuit of a control circuit, a test signal from the test ground path;
- and
- determining, by a controller of the control circuit, the grounding state based at least in part on the test signal,
- wherein the test ground path operatively couples the ground detection circuit to the subwasher.
A washing machine appliance, comprising:
- a subwasher;
- control circuit, comprising:
- a ground detection circuit configured to receive a test signal from a main ground path via a test ground path;
- and
- a controller configured to determine a grounding state of the subwasher of the washing machine appliance based at least in part on the test signal;
- and
- wherein the test ground path operatively couples the ground detection circuit to the subwasher permanently coupled with the main ground path.
