If a washing machine has an issue with too much water in the tub and not enough suction, there could be several possible reasons for this problem:
Clogged or obstructed drain hose: A clogged or partially obstructed drain hose can prevent water from draining properly, causing the water level in the tub to rise. Inspect the drain hose for any blockages or kinks that might be impeding the flow of water and clear them if necessary.
Drain pump malfunction: The drain pump is responsible for removing water from the washing machine's tub during the drain cycle. If the pump is faulty or not functioning correctly, it may not be able to remove all the water, leading to an excessive water level in the tub. The pump may need to be repaired or replaced.
Drain pump filter clog: Many washing machines have a drain pump filter that traps debris and lint from the water. If this filter is clogged, it can impede the draining process and cause water to accumulate in the tub. Cleaning or replacing the drain pump filter may resolve the issue.
Water level sensor or pressure switch malfunction: The water level sensor or pressure switch detects the water level in the washing machine's tub and signals the machine to stop filling with water once the desired level is reached. If this sensor is faulty, it may not detect the water level correctly, leading to overfilling. Testing and replacing the water level sensor might be necessary.
Malfunctioning inlet valve: The inlet valve controls the flow of water into the washing machine. If the inlet valve fails to close properly, it will continuously allow water to fill the tub even when it shouldn't, resulting in an excessive water level. Replacing the faulty inlet valve may be required.
Electronic control board issues: The electronic control board is responsible for coordinating various functions of the washing machine, including water levels. If the control board is malfunctioning or there is a communication error, it may cause incorrect water level readings or issues with the water intake process.
Improper installation or leveling: If the washing machine is not installed correctly or not properly leveled, it might lead to issues with water drainage and suction. Ensuring that the machine is level and correctly installed can help improve its performance.
If you encounter any of these issues with your washing machine, it's best to consult the manufacturer's manual or seek help from a qualified appliance repair technician to diagnose and fix the problem safely. Washing machine repairs can involve electrical components and water, so caution is necessary.
