Question about Fisher and Paykel (IWL12)

Fisher and Paykel Smartdrive 053 Hot Water filling very slowly

I've cleaned filters, switched hoses, and basically come to the conclusion that the HW solenoid is energised but clogged (I can also see discoloration compared to the cold water one).

I wanted to see if I could clean it, or replace it myself if required. I managed to remove the coil but can't see how to disconnect the valve from the mixing tank - can someone help me - it's all plastic and I don't want to start twisting, turning, bending, prying etc without knowing how it is supposed to come apart.

Thanks in advance.

    OK - I couldn't help myself. I got the solenoid free.

    Unplug the washer, remove the hoses, remove the two screws that are in between the hose connections. This frees the plastic clamp, remove it. The solenoids then pop out of the mixing tank pretty easily but can't be removed all the way yet. Remove the screw in the middle of the mixing tank, remove the screw holding the large green plastic thing, gently raise the mixing tank to unseat the tank, this then gives enough room to remove the solenoid valve.

    So here is my next question - poking a thin screw driver up into the valve showed the pin moved - I rinsed/soaked it with vinegar hoping this might dissolve any mineral buildup - put it all back together and unfortunately the problem had not improved. I think I'm going to order a new solenoid coil and valve but wanted to know if anyone has any bright ideas before I do.

    Thanks RescueTech - I'll place an order (for both). You don't happen to know the Australian equivalent for the link you posted do you ?

    cold water is the problem, almost no cold water coming out.

    I have a similar problem but mine is with a Smartdrive 051 and its my cold water. My cold water inlet valve is just allowing a trickle of water in. The hoses are fine, the plastic filter is clean, so I wanted to change the inlet valve.

    I opened up the top and tried to remove the valve after following the steps outlined in Greg's post. But I got to the stage where I had to remove the screw holding the large green plastic thing. I don't have one - what is being referred to? I have a large purple plastic thing that looks like it is a housing for electronic bits. It takes up the rest of the area next to the mixing tank. I have undone the single screw that holds this in place and it can move. But its attached to the mixing tank and the mixing tank doesn't seem to raise. I have undone the tank's screw and the plastic clamp just like in greg's post.

    The mixing tank is connected to the purple plastic bit and I don't know how to disconnect this part - if I could then the mixing tank could be freed.

    Can you give more instructions? I have the cold water inlet valve and am ready to change it.

Hi Greg. If I may be candid here? As a technician with years of daily experience repairing appliances, I would advise you and anyone else who happens across this post to take my advice and NEVER, EVER try and "clean" or take apart a water inlet valve in order to try to save a few bucks, When it works, sure, you feel good about how you've saved some money. The problem is, sometimes tiny particles get past the diaphragm and you can end up with a major flood situation if it sticks open. I've seen this too many times and I am here to tell you that damage that can be done to a home, especially one with an up-stairs laundry room with no floor drain can run into the thousands of dollars, all because somebody wanted to save the cost of a water inlet valve.

Just replace the valve. In fact, on machines where there are separate hot and cold, if we go out on a job where one is faulty, I tell the customer we should change them both as a set.

Your question is posted under the IWL12 series, so the part number for the hot water inlet valve is a 420237P. You can get them here:

I hope my candor is not taken wrong, but don't go the cheapo route here, this can turn into a HUGE mess, you can't exaggerate this point. I have seen where people dismiss this advice and end up with a caved-in celing in the room below the laundry after the solenoid sticks open and they happen to be out shopping or walking the dog as the washer keeps filling and filling and filling and... well, I think I made my point. :)

Smartdrive 508 fills very slowly, seems to "time out". To get the cycle finnished we have advanced the cycle.

Hi just read your posting.Is your complete model number GW 508? The fault with your machine is either your inlet hose filters or your water valve filters are blocked or one or both of your water valves are faulty.Turn off the water to your machine and remove the inlet hoses one by one.Check the amount of water coming out of the taps and check and clean the filters,if your inlet hoses have them, at each end of both hoses.Also where the inlet hoses connected to your machine check the filers on the water valves.If all the filters are clean and you still have the problem then the problem will be one or both of the water valves.Please reply on how you got on or for additional assistance.Hope this helps and looking forward to your reply.

No water flow on Fisher and Paykel smartdrive 708 washing machine

Take the lid off,just open it & pull it straight up.There should be a little red button that the lid strikes against unless its a different model,in that case it has a magnetic reed switch under the right hand side of the this red switch instead of closeing lid,see if it fill with no problem.the lid may not be making good contact with switch..if thats not it then it may be the inlet valve..then you can try the hot,if theres no problem with hot then its the cold valve.

My fisher & paykel smartdrive 5.5kg toploader leaks into the tub. it also has just started to fill slowly from the hot tap. i have removed the hose and cleaned filters. any ideas? could it be the...

Sounds like problem with inlet valve solenoids. There is one for the hot, and one for the cold. Fairly easy to replace if you are a confident DIYer- Disconnect from power, remove two screws holding top control panel on. You will see inlet valves on left hand side (the inlet hoses are attached to the valves, so you need to unscrew hoses). Two screws on rear of valves to remove grey plastic retainer, then valves pull up to remove. There is a rubber grommit on bottom of valves- retain this as some new valves do not come with this piece. New valves available from any good appliance repair shop. Call in the experts if you are in any doubt!!
