If there is excessive water left in the washing machine after it drains, several possible reasons could be causing this issue:
Clogged or Partially Blocked Drain Pump: The drain pump is responsible for removing water from the washing machine during the drain cycle. If it becomes clogged with debris or foreign objects, it may not be able to pump out all the water effectively.
Drain Hose Obstruction: The drain hose that carries the water from the washing machine to the household drain or standpipe could be partially blocked or kinked, hindering the smooth flow of water.
Drain Filter or Trap: Some washing machines have a drain filter or trap that captures lint, coins, and other debris from the laundry. If this filter is clogged, it can impede the draining process.
Incorrect or Insufficient Drainage Height: The washing machine's drain hose should be installed at an appropriate height to allow water to flow freely. If the hose is too low or too high compared to the recommended height, it can lead to improper drainage.
Problems with the Water Pump: If the water pump itself is faulty or not functioning correctly, it may not be able to expel all the water from the machine.
Control Board or Sensor Issues: Electronic issues with the control board or sensors that manage the draining process could cause incomplete draining.
Washer Load Imbalance: Sometimes, if the laundry inside the machine is unevenly distributed, it can affect the balance of the washer drum, leading to incomplete draining.
Siphoning Effect: If the drain hose is inserted too far into the standpipe or if there is no air gap between the hose and the drain, a siphoning effect can occur, causing water to flow back into the washing machine after draining.
To address this problem, you can try the following troubleshooting steps:
Check the drain pump, drain hose, and drain filter for any blockages or obstructions. Clear out any debris if necessary.
Ensure that the drain hose is positioned correctly, neither too high nor too low.
Inspect the water pump for any signs of damage or malfunction. If it's faulty, it may need replacement.
Verify that the control board and sensors are working correctly.
Make sure the washing machine is not overloaded or the load is evenly distributed.
If you are uncertain about diagnosing or fixing the issue, it's advisable to seek assistance from a qualified appliance repair technician or contact the manufacturer's customer support for further guidance.
