How to Replace the Inlet Valve on a Washing Machine

Each part of your washing machine is import, and one such part is the inlet valve which controls how much water goes into the appliance during a wash cycle. Unfortunately, the inlet valve (particularly the cold inlet valve) can become faulty, with a main cause of the fault being the cold water freezing inside the pipe during the winter weather.

In the above video, with the help of our experienced team, we explain how to replace the inlet valve on the washing machine, and below we’ve compiled a simple step-by-step guide which takes you through every point covered in our video.

Step 1: To replace the inlet valve on your washing machine, you’ll need to remove the top panel of your washing machine, by unscrew the screws holding it in place.

Step 2: With the top removed, you’ll be able to locate the inlet valve; with the valve located remove the connection block, before using some pliers to unclip the two hoses from the valve, enabling you to take the hoses off.

Step 3: Unclip the valve from the main chassis of the appliance, by placing a flathead screwdriver underneath the bottom of it and levering it out.

Step 4: Attach the new inlet valve on your washing machine by reversing the steps above, and see your machine work to its full potential again.

There you have it, a step-by-step guide to replacing the inlet valve on a washing machine, helping it to perform to its optimum level.

Video Transcript

Hi, I’m Rory from eSpares and in this video, I’m going to show you how to replace the inlet valve in this Bosch washing machine.

We are round the back of the machine, just to show you how the water goes into the machine. It goes through the inlet hose, through the inlet valve and into the machine.

Now the inlet valve controls how much water goes into the machine and when it goes in during the cycle. There are two types of inlet valve; there’s a hot water valve and a cold water valve. However, in most modern washing machines, only the cold water valve will be plumbed in.

Now, how do you know if your valve is damaged? It’s most likely to happen during cold weather. Cold water inside the inlet valve can freeze and therefore expand and crack the valve causing leakage. So, if you’re finding water leaking at the back of the machine or underneath and its definitely not coming from the door seal at the front, then the chances are you’ll need to replace the inlet valve. Especially if the leaks are occurring during or after particularly cold weather.

So, here we have a selection of different inlet valves. They come in all different shapes and sizes, from this simple one-way hot water inlet valve to the more complex, like this four-way cold water inlet valve which sends water into four different directions in the washing machine and also had four valves, like you see here. 

But it doesn’t matter how simple or complex the inlet valve is in your washing machine. 

The most important thing you need to make sure of is that you get the right inlet valve for your washing machine. To do this, you’ll need your washing machines model number, this can be found either on the inside of the door around the front, or like on this washing machine, on this label on the back.

Now, what I’m going to do is replace the two-way cold water inlet valve on this Bosch WFL series washing machine. 

Safety first, make sure your washing machine is unplugged before you get to work and you’ll need to get your washing machine into a big, open space, just so that you have enough room to work on it. The first thing I need to do is remove the top panel. To do that, I’m going to need to remove the screws holding it in place at the back. They are held in place with Torx head screws, you can get a Torx set on the eSpares website, I’m going to use a Torx bit on the end of a driver.

So here we have our cold water inlet valve. The first thing I’m going to do is remove this connection block. There you go. Now, I need to take these two hoses off at the valve so I’m going to need some pliers to unclip them, just like that, Now, I can just take the hoses off.

The unit valve is actually clipped into the main chassis of the machine and there’s a bit of a knack to removing it. You can either put your flathead screwdriver underneath the bottom of it and lever it out, or the slightly easier way, of getting your screwdriver and pushing forward on it from back, just like that, and then using your hand to lever it out. There you go, and it comes away just like that.

To fit the new valve, all you need to do is repeat all the steps you’ve just taken, but in reverse. There’s nothing wrong with this valve, so I’m just going to refit it to the machine.

That’s how easy it is to replace the inlet valve in this Bosch washing machine. Inlet valves for all make and model of washing machine are available on the eSpares website.

Thanks for watching.
