Abstract
A method for cleaning a drain line of a dialysis machine downstream of a filtration unit. The method includes closing inlet and outlet valves of the filtration unit, and closing a bypass valve along a bypass line that connects a source line to a drain line. The method also includes configuring the balancing chamber such that flow is permitted only via the drain line, flowing an amount of a cleaning agent into the drain line through a cleaning agent valve, and rinsing the cleaning agent from the drain line with a rinse fluid.
