Washing machine is constantly filling or filling when switched off
This video will explain how the water intake system works on your washing machine
If your washing machine is constantly filling or filling when switched off then this is the right tutorial for you.
There are basically a few reasons why this can happen and I will explain them all and how to rectify them. We have included some videos to help you understand the fill system.
If water is going into washing machine when switched off. (Sometimes overnight)
- A water valve is jammed open (usually because grit has got in the valve) on rare occasions there can be power going to the valve (usually a short circuit on the mother board) the water in the drum will be clean.
- The waste hose is connected to the sink unit and when you let the sink water go it back flows into the washing machine via the waste hose. the water in the drum will be dirty
( a customer once complained to me that the machine I sold him was full of bits of food. when I went to his house I found the he had connected the waste up to some plumbing from the waste compacter and when he used the compacter it was pushing the rubbish down the waste pipe into the washing machine, I could not stop laughing and he felt slightly embarrassed about his foolishness)
If the washing machine is constantly filling with water but drum never over fills
- This is normally the waste hose is to low and the appliance is either syphoning the water out or just flowing out the waste. See picture below for correct fitting.
Check the drain hose is installed properly
During the wash cycle the washing machine is over filling or water is constantly going into the machine.
- The water valve may be jammed open. Sometimes by removing the soap dispenser drawer and carefully observing inside the soap dispenser you can clearly see water slowly dripping in, don’t do this straight after using it wait a while, you will also be able to tell which valve is at fault by the area in the draw that it is leaking.
- As the appliance goes into to rinse it starts filling, then does not stop. Syphoning is normally the problem here check the air gap is good on the waste and the pipe has not been pushed too far down waste standpipe/ stanchion. See picture below for correct fitting
- The pressure switch has failed. Rare but it happens.
- The pressure switch pipe that comes from the pressure bowl has a hole in it. This happens when the pipe wares against the drum chaffing the rubber.
- The pressure bowl is blocked this is normally with silt or washing detergent also check the pipe as they can block as well.
- On most commercial machines you have a sluice gate pump this can get jammed open with all sorts of things the most common is bra wires. If open it will still run but be costing you a fortune in water.
I hope I have sorted out your problem with this article.
