It's not entirely clear what you mean by "washing gun" in this context, but I'll assume you're referring to using a pressure washer or a high-pressure water gun to wash something while your washing machine is also running. If that's the case, the water you see in the spinning hub of the washing machine may be due to a couple of reasons:
Splashback: When using a pressure washer or water gun, the force of the water can cause splashback or splatter, especially if you're washing nearby the washing machine. Some of this splashing water may find its way into the spinning hub or other parts of the machine.
Leaks or Loose Connections: Another possibility is that there might be a leak in the washing machine's water supply or drainage system. Leaks can occur due to damaged hoses, loose connections, or worn-out seals. When the washing machine is running, the spinning action could cause the water to move around and collect in the hub.
Regardless of the specific reason, it's essential to address this issue to prevent potential damage to your washing machine. Excess water in the spinning hub or other parts of the machine could lead to corrosion, electrical issues, or other malfunctions over time.
Here are some steps you can take to resolve the issue:
Inspect for Leaks: Check the hoses, connections, and seals of your washing machine for any signs of leaks. If you find any, replace or repair the affected parts.
Keep a Safe Distance: Try to keep a safe distance between your pressure washer or water gun and the washing machine to minimize the chance of splashback.
Timing: If possible, avoid using both the washing machine and the water gun simultaneously. Instead, schedule them at different times to prevent any interference.
Clean the Washing Machine: If water has accumulated in the spinning hub, carefully clean it out. Make sure the machine is unplugged before attempting any maintenance or cleaning.
If the issue persists or you're unsure about handling the problem yourself, it's best to consult a professional appliance repair technician. They can thoroughly inspect your washing machine, identify the source of the water, and carry out any necessary repairs to ensure proper functioning.
