Abstract

A method for controlling additive deposition in a washing machine appliance includes transmitting, after a first agitation of a load within a tub of the washing machine appliance, an additive deposition signal to a user of the washing machine appliance. The method further includes beginning a timer, the timer set to run for a predetermined time period. The method further includes determining whether a door of the washing machine appliance has been opened after transmitting the additive deposition signal and during the predetermined time period. The method further includes determining whether the door has been closed when the door has been opened during the predetermined time period, and performing a second agitation of the load when the door has been closed. The method further includes performing the second agitation when the door has not been opened during the predetermined time period after the predetermined time period has been reached.

First claim

What is claimed is:

1. A method for controlling a washing machine appliance, the method comprising:
transmitting, after a first agitation of a load within a tub of the washing machine appliance, an additive deposition signal to a user of the washing machine appliance;
beginning a timer in response to transmitting the additive deposition signal, the timer set to run for a predetermined time period following transmitting the additive deposition signal;
determining whether a door of the washing machine appliance has been opened after transmitting the additive deposition signal and during the predetermined time period;
determining whether the door has been closed when the door has been opened during the predetermined time period; and
performing a second agitation of the load in response to one of a plurality of conditions, the plurality of conditions comprising
the door has been closed if it has been determined that the door of the washing machine appliance has been opened after transmitting the additive deposition signal, and
the door has not been opened during the predetermined time period after the predetermined time period has been reached.

2. The method of claim 1 , further comprising determining a requested number of additive deposition signals based on a signal received at a controller.

3. The method of claim 2 , wherein the requested number of additive deposition signals is based on a number of signal input at a user interface device.

4. The method of claim 2 , further comprising:
determining, after the predetermined time period has been reached and before performing the second agitation of the load, whether each of the requested number of additive deposition signals have been transmitted; and
repeating the transmitting step if each of the requested number of additive deposition signals have not been transmitted.

5. The method of claim 1 , wherein the additive deposition signal is transmitted to a signal output device of the washing machine appliance.

6. The method of claim 1 , wherein the additive deposition signal is transmitted to a user interface device.

7. The method of claim 1 , further comprising:
flowing a water volume into the tub; and
performing the first agitation of the load.

8. The method of claim 7 , further comprising:
draining water from the tub after performing the second agitation; and
performing an extraction of water from the load.

9. The method of claim 8 , further comprising:
flowing a water volume into the tub after draining water from the tub;
performing a rinse of the load; and
draining water from the tub.

10. The method of claim 1 , wherein the additive is bleach.
