I’m working on a LG washer WM1812CW where the water level is too low. In a normal wash the clothes will get wet but there is no shallow pool of water to plop into.
In diagnostics I get a water level reading with 2 digits 51 when empty and 42 when the water valve shuts off with a reasonable amount of water in the washer.
From the troubleshooting guide I should be seeing 3 digits as in “241: a Water level frequency of 241 x.1 kHz = 24.1 kHz “.
This started with owner washing an old dog blanket that had come apart in the wash. He cleaned out the drain but the water level was never the same after.
To be throe I removed the rubber bowl under the tub and blew through the water level hose . There was no obstruction and the bowl was perfectly clean.
At this point I changed out the water level switch with no change . In diagnosis a 2 digit display of 51-42.
I have changed out water level switches on LG front loads before. In both cases the water levels were too high with water leaking out the door boot.
In diagnostics on these two I saw a 3 digit reading of around 215 before changing the part and testing with reading within range of 250-650 after and proper water levels after.
Any ideas where to go from here.
