Where do these parts inside water valve go?


Recommended Posts

Hi there I have recently purchased a hoover h wash & dry 300 plus / washer dryer I was told from the place of purchase I simply had to replace the existing machine using all the same hoses from the previous which I have done . After attaching the new one and attempting to start an eco wash nothing happened when I went to recheck upon unscrewing the water pipe it spat out 3 valves at me please can someone help me explain this as to what these are and maybe a possible solution Thank you kindly Damian

Hello Damien. I've had this before, someone that I know sent me a photo of exactly the same parts. I can't be 100% certain, but I know for a fact that the one with the small rubber seal on top is called a flow restrictor. Its job is to restrict the flow of water in a cold water valve because some people's water pressure may be too high, which would cause leaks in the soap dispenser.

This part has always gone into the water valve first, with the black rubber seal facing you. Use pliers, preferably not narrow nose pliers which can slip and damage the parts. This part may well be quite a tight fit, although presumably not necessarily as it wouldn't have come out so easily. In my experience this part has always taken some effort to pull out so it is very surprising that it came out so easily.

You need to try and place it into the valve as level as possible. If you try to put it in at an angle it may jam. Anyway place it as far back as it will go.

The last one, the plastic filter with all the holes in is the filter. That has always gone on last. Using pliers grip the small tab sticking out of the centre and carefully place it in situ. Be careful this part is usually quite delicate. You do not want to crack or otherwise damage it because it could then let small particles of impurities from the water inside the water valve and cause it to not close off properly.

So the orange one in the middle is one I've not come across. I can only assume it must go in the middle though you have to use your judgement as to which way round it goes. If there is a small tab on it somewhere that would facilitate pulling it out then I would suggest that that would indicate the side that should face you.

I've no idea what it does, and I can assure you that for the 40 years I've worked on appliances water valves have never had one, so I would stick my neck out and say that it is not necessarily strictly necessary if you know what I mean.

I wonder if the middle bit is an aerator? (mixes air and water together) - I have come across these in the outlet of mixer taps , the ones you get for kitchen sinks and that ,  create bubbles with the water as the water mixes with air - and possibly help to oxygenate / mix air with the water before it goes into the soap drawer (water Air helps mix the detergent more effectively ) as well as cutting down on water

Here is a mixer tap aerator :

Interesting theory Andy. I don't think it will help reduce water usage though as obviously washing machine takes in a specific amount of water but as you say does help reduce water usage in a water tap. I have to say that it does at least make some theoretical sense because apart from a filter and a flow restrictor I cannot think of any other thing necessary inside a water valve.

I must have a look on our new Samsung washer and see if there are any restrictors in that cold fill inlet valve on ours because the water pipe I am going to be linking it up to will be a low pressure supply from the cold water header tank up in the loft. - if we have got a restrictor in it I will have to see if it will come out

hello Andy - I trying to see if i have a water pressure restrictor in my machine if so i want to remove it , so i have undone the cold fill pipe and pulled out 1 filter and then there was another metal mesh filter. 
If you look at the pic of my cold water valve does that look like there is a restrictor in there that I can pull out or is that actual middle bit part of the solenoid valve seal? 
Thanks.

Hi Andy. It’s still in the valve with the rubber seal on. Use narrow nosed pliers to pull it out. It may be tight but should normally come out.

so you see in the pic the hoover restrictor has a hole in the middle and the samsung one is blanked off that will have no issues on removing it , and it should still come out ok and work without it do you think?

Hi Andy. Yes the Hoover one is easy to remove with narrow nose pliers because you can slip one of the sides of the players into that whole. With the Samsung one, I would expect ordinary players would be better at gripping the protruding plastic in the centre. It's just whether or not they will fit inside the aperture of the valve. If it does not come out by any chance, then presumably removing the rubber washer may still help.

Bear in mind that flow restrictors are fitted to prevent problems if the water pressure is fairly high, so I only ever removed them in situations where people had very low water pressure. It did make a difference by the way.

So, i got the pliers out today. Tugged at the purple plastic bit inside the valve and it was not budging at all. So I got a screwdriver where the rubber washer was and levered that out OK , so thats it, that was the restrictor then - now thats removed it does fill a little faster now so that's good now - turns out the middle purple bit was part of the valve itself

should imagine a job of the restrictor would also be to cut down on 'water hammer' in the mains water piping as well as stopping the leaks in the soap dispenser too Andy on high pressure water mains as the machine solenoid operates on and off (or open and closing)  , would I be right in saying that?

Hi Andy. Leaks in soap dispenser are the main reason. I’ve never understood why they don’t have a proper seal on them. When Dustin made their washing machine they had one.
 

Water hammer might be a bonus though I’m not sure washing machine manufacturers would worry about that. Maybe though, if they get people blaming washing machine.
