Hi,

Really need help here. I have a 9 year old LG washing machine, top load. The problem I am facing right now is that, the minute I turn on (pressing the On/Off) button, water starts flowing into the drum without me even selecting any type wash cycle of anything. And it will keep on flowing until spills over. The only way to stop the water from flowing is I turn off the electric supply or I pull the plug from the solenoid valve.

I have replace both the solenoid valve and the pressure switch and the tubing that connects the pressure switch to the drum, but it's still the same. I am really lost.

Solution Summary

AI-generated from this discussion

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

LG top-load washer fills with water as soon as it is switched on

The problem
A 9-year-old LG top-load washing machine starts taking in water immediately when the On/Off button is pressed, before any wash programme is selected, and continues filling until it overflows. The water only stops if the electrical supply is turned off or the solenoid valve is unplugged.
Likely cause
The accepted reply says the inlet valve is likely being energised whenever the machine is powered, possibly because it is switched via the neutral return and there is a leak to earth somewhere. This was presented as a possible explanation rather than a confirmed fault.
What fixed it
Do not replace any more parts speculatively. Further diagnosis should be carried out by a suitably qualified appliance engineer.
Checks to try
  • Solenoid valve replaced
  • Pressure switch replaced
  • Tubing between pressure switch and drum replaced
  • Observed that filling stops when electrical supply is turned off
  • Observed that filling stops when the solenoid valve is unplugged
Parts or tools mentioned
  • Solenoid valve
  • Pressure switch
  • Pressure switch tubing

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

The valve is possibly powered up all the time the machine is on and is switched on by making the neutral return. One possibility is a leak to earth somewhere causing the valve to energise. I would get an engineer to look at it. Don't replace any more parts. Speculatively replacing parts is just nuts to be honest.

Thanks for the reply. I guess I have to really call an engineer now.
