Whirlpool washer doesn't hold the water when filling for the wash cycle
The washer is a Whirlpool LAA580 and it is old maybe more than 20 to 25 years old. This washer has given super service for so many years and just seems to go and go like it never wants to quit doing it's job.Answer
But now for some reason or rather when it is filling getting ready for the wash cycle it doesn't want to hold the water such that the tub would fill up to where it would normally start agitating. Sometimes it will hardly hold any water and other times the water level will come up higher but not high enough to start the agitation. There are no leaks. Sometimes it will fill part of the way up but not enough to start the agitating and when it does this I turn the water level switch to a lower level and it will start agitating. Then I turn the water level switch up to the higher level I had selected to start out with and then it will hold the water and fill properly and then start agitating normally. Thanks for your help.
It sounds like the water is siphoning out or running out the drain. These are things that can cause this condition.
The top of the drainpipe to your house plumbing must be above the highest water level in the tub. If not, the water will start draining once the water in the tub reaches a level above the top of the drainpipe. Sometimes the drainpipe will slip down under the house too far and you can simply pull it back up and secure it in place. If you are unable to do that, you can extend the drainpipe using a coupling and a short piece of pipe of the same size. Sometimes you are unable to do this because the pipe is inside a wall, if this is the case you can try running your drain hose from the washer up high to compensate for the low drainpipe.
If the drain hose from your washer is pushed down in to the drainpipe too far it will cause the same problem. To fix this simply pull the drain hose to within six inches of the top of the drainpipe.
Another thing that will cause this is that the water is siphoning out. The water will siphon out if the drain hose cannot get air. The most common thing that causes this is that someone taped the drain hose to the drainpipe so that the water will not back out the drain during pump out. The best way to fix this is to clean out the drainpipe so that the water drains freely enough that it doesn’t back out and remove the tape from the drain hose. Sometimes, especially on old houses, the drainpipe isn’t big enough to drain the water no matter how clean it is. In this case, to fix this problem you will have to install a siphon breaker (part number 76660) at the top of the drainpipe to allow the drain hose to receive air and still be taped up so that the water will not back out.
