If your washing machine continues to drip water even after you have turned off the hot and cold water valves on the wall, there could be a few potential causes:
Water pressure: Sometimes, water can continue to flow due to residual pressure in the pipes. This can cause a slow drip even when the valves are closed. To alleviate this, you can try turning on another faucet in your house to release the pressure, which may help stop the dripping from the washing machine.
Faulty valves: The valves on the wall may not be shutting off completely, resulting in a persistent drip. Over time, valves can develop wear or mineral buildup, affecting their ability to seal properly. In such cases, you may need to replace the faulty valves to prevent the dripping.
Faulty inlet hoses: The dripping could be occurring from the inlet hoses themselves. Check if the hoses are securely connected to both the washing machine and the wall valves. It's possible that the hose connections are loose or worn out, causing water to leak even when the valves are closed. Tightening or replacing the hoses may solve the issue.
Internal washing machine issue: There could be an internal issue with the washing machine, such as a faulty water inlet valve or a malfunctioning water level sensor. If the dripping persists despite checking the external factors, it's advisable to contact a professional technician or the manufacturer's customer support for further assistance.
It's important to address the issue of a dripping washing machine as prolonged dripping can waste water and potentially lead to other problems.
