I have a LG frontloading washing machine that is about 8 years old. I have replaced the water discharge pump two times now. The motor was always ok, but the plastic "vane" would break and free spin on the motor shaft.
How much water should I be able to drain out of the hose on the bottom left after it is fully pumped out? Benchmarks I have done are typically between 4-5 cups (about a quart). The water is "cloudy" and doesn't smell clean. Is it reasonable to expect this much residual water? My wife says it is causing the clothes to smell bad if left in the washing machine for more than 30 minutes. She also thought in the past it never required draining this much water (i.e. when cleaning the filter).
- I am pretty sure there is no blockage.
- I have run the test mode, and all seems good. The "frequency" does go up when the water drains.
- Could it be the water level sensor? And this might be preventing it from fully draining?
- The discharge standpipe is about 4 feet above floor level. Someone thought it could be a bad check valve, letting water contained in the hose flow back into the tub when the pump stops.
Any ideas would be greatly appreciated.
