Claim 0:
1. A method, comprising:
receiving, by a computing device configured to control a plurality of valves, user input to initiate washout of a rear portion of a concrete mixer truck; and
in response to the user input, performing, by the computing device without further user input, washout of the rear portion of the concrete mixer truck, including by:
causing, by the computing device, a first valve of the plurality of valves to be opened, wherein the first valve is configured to control water flow to a first subset of spray headers that are positioned to clean a first portion of the concrete mixer truck;
determining, by the computing device, that a first condition has been met;
in response to determining that the first condition has been met, causing, by the computing device, the first valve to be closed;
subsequent to causing the first valve to be closed, causing, by the computing device, a second valve of the plurality of valves to be opened, wherein the second valve is configured to control water flow to a second subset of spray headers that are positioned to clean a second portion of the concrete mixer truck;
determining, by the computing device, that a second condition has been met;
in response to determining that the second condition has been met, causing, by the computing device, the second valve to be closed; and
controlling turning of a mixing drum of the concrete mixer truck while at least one of the first valve or the second valve is open.
