LG Washing Machine - working fine, except when trying to fill up with water.
Hi.
Does anyone know what could be the issue here?
Our washing machine works fine, except when I start a wash, it sounds like it’s attempting to pull the water into the washing machine several times before actually fill up.
(Not sure if this is useful information but we live in a 1970 block, we have a dishwasher and washing machine attached one pipe using a splitter. (not a plumber so might not be explaining this well))
Thanks!

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
LG washing machine intermittently energising water fill
- The problem
- The LG washing machine otherwise operates normally, but at the start of a wash it appears to try several times to take in water before it finally fills. The machine sounds as though the inlet valve is only being activated briefly.
- Likely cause
- The strongest diagnosis in the discussion is that the water inlet valve is being energised for only a fraction of a second because it is not receiving a proper voltage supply. A less likely but mentioned possibility is an internal fault or poor connection within the water valve coil/terminal area. A PCB fault was also suggested as a possible cause. The shared water supply with the dishwasher was not considered a problem provided both appliances are not used at the same time.
- What fixed it
- No confirmed repair was documented. The accepted advice was that this is difficult to investigate and an engineer may be needed to diagnose whether the issue is with the valve connection or the PCB supply to the valve.
- Checks to try
- Observed that some water does enter the machine
- Considered whether the inlet valve is opening briefly
- Considered the shared water supply arrangement with the dishwasher
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hi. Yes it sounds like the water valve is energised for just a fraction of a second. It does sound like some water goes in. So that would suggest that there is a supply of water to the valve, and that the valve is capable of opening and letting water in. It just sounds like the valve is not getting a proper supply of voltage.
It is possible for the valve to be faulty, I've had water valves in the past where when I carefully moved the wire up and down the water valve switched on and off. This was caused by a faulty connection inside the water valve just where the amp tag connects to the coil. It is rare though.
Another possibility is that something is just gone wrong with the PCB. Unfortunately it's very difficult fault to investigate so you may need to get an engineer to look at it.
Regarding the water supply being shared by the dishwasher via a white piece. That should be fine as long as you never put them both on at the same time.
