Same problem, pause during the time when the machine was suppose to drain the water. Service technician came:
1. Water drainage pump had a bent propeller shaft, possibly due to dislocation by debris. Excess friction with the housing may have occured.
2. Power supply board to the pump overheated with blackened components. Possibly due to the pump overcurrent causing the components (power IC, resistors, capacitors) in the blackened area to fail over time.
Both the drainage pump and the power supply board for the pump had to be changed. After that, everything worked fine.
I also had clean away the hardened detergent around the pump O-ring mating with the housing, and in the drum. It looks like I was using detergent excessively, and over time, leftover had hardened and occasionally dropped off as hardened debris that can damage the pump.
Lesson: It is important to limit the amount of detergent, regularly run the drum cleaning program, and clear the pump filter of debris. The frequency is probably once a month or 2 months. While checking the filter and the pump propellers, be careful not to poke the propellers too hard, because you may dislocate the propeller shaft permanently, thereby also causing excess propeller friction too. Overheating of the pump power supply PCB will occur.
The first earliest symptom of this drainage pump obstruction + power supply failure is: a loud clanking sound 20 mins after the start of the Daily Wash cycle. If you hear this everytime, this means your pump is about to fail. The machine should always run quietly.
