LG WM-1460F(H)D

[admin]

Hello

I have a LG WM-1460F(H)D washing machine and I think I might have a problem with the pressure valve switch. Could anybody tell me if when I blow into the valve I should hear a click as with other makes of switch? The problem with the machine is that the cold water is not switching off and the machine overfills. I am wondering if the pressure valve switch is the cause of the problem?

Any help would be very much appreciated.

Thanks

Don’t know the model you refer to but if it’s the electronic pressure switch then there is no click heard at all. They’re normally very small and just a plug and socket job for the electrics.

Re: LG WM-1460F(H)D

This is a electronic model which you cannot hear any click ect from the pressure switch…you may well cause damage to the switch assembly as the pressure required on this type of sensor is minimal.

Does the machine overfill whilst the machine is unplugged or is it whilst it is washing.

Depending on this depends on where the fault will lie.

Thanks Bryan. It’s just when it’s washing.

Hello Guest,
We work on quite a lot of LG washing machines and have come across your problem before, as rightly said the pressure sensor does not click,i wonder if the machine displays any error codes. Anyway try cleaning the pressure chamber at the side of the tub or simply blow down the hose.
Let my Know how you get on. Bob.

Hello Bob. It does give an error code FE when the machine is too full but it won’t stop filling. I have cleaned the pressure chamber out and checked for any blockages in the tube. I was kind of narrowing it down to either the pressure switch or some fault with the main board. I wouldn’t know how to test if the switch was indeed faulty?

I have tried getting hold of a replacement switch without much luck. Would you know where I could get one from? I’ve spoken to LG and to be honest they weren’t much help. As you probably know all there parts are supplied by Seme and I’d already spoken to them. They didn’t even have a pressure switch listed on their system so they have sent an ‘enquiry’ out which could take up to three days. Any suggestions would be much appreciated.

Re: LG WM-1460F(H)D

Just an observation I’ve made. Of the cold water inlet valves the right one (looking from the front of the machine) is the one which takes most of the water. The left one seems to be used mainly on the final rinse. The right one will not stop taking water, the only way to stop it is to disconnect it. But the left one when it is used on the final rinse does stop on it’s own. I’m not sure what this tells me?
I’ve tried switching the cables over from valve to valve but it makes no difference. Any ideas?
One thing which I haven’t mentioned is that the machine did recently have a faulty coil which was replaced. Could this have any bearing on my current problem?

Does the valve start filling immedietly the machine is powered up ?

Which coil was replaced ?

Hi Dave
It was the right one which was replaced.

It starts filling once the programme has been selected and the start button has been pressed, after that it just won’t stop.

Re: LG WM-1460F(H)D

I would then cast some doubt on the suitability of the coil fitted.

There is as far as I know no manufacturer that will supply only the solenoid coil for the valves, only the whole valve assembly (LG certainly don’t). It is fairly common practice though to just pull the coils off and replace them indiviually on many appliances, but, considering this is a totally electronically controlled appliance the valve coil voltage and resistance will be fairly critical.

It may be worthwhile replacing the whole valve first, then the pressure switch, if both of these fail then the main control pcb will be at fault.

It may be though that the pcb is already faulty, caused by the old solenoid coil.

HTH.

Re: LG WM-1460F(H)D

Thanks Dave. Would it not be possible to switch the connections over from the replaced coil to the other coil. I have tried this but it doesn’t make any difference. Will the valve coil voltage and resistance be different on the two cold water valves and the hot water valve?

Re: LG WM-1460F(H)D

If it makes no difference swapping the leads around then either the pressure switch or the pcb are at fault and I would suspect the latter as I have never had cause to replace a pressure switch. If I were you I would call someone out who has the experience of these appliances to make a better diagnosis for you as we are stabbing in the dark a bit here. It may well be something quite silly that could be resolved which will save you unnecessary expense and hair pulling 😉

Also as this is a public forum I can’t be too specific on diagnostics as I place myself at risk if you cause yourself any harm carrying out any advice I may offer.

If you pop you’re postcode up here, someone no doubt will be able to help with a call for you.

Re: LG WM-1460F(H)D

I have come across this problem before and it was the pcb which was at fault,which i have got in stock.I cannot guarantee this is definetly the problem without seeing the appliance but the pcb cured the last one i had.but i have to advise you against working on the appliance without being qualified and any parts fitted are at your own risk,any advise given in this forum should only be acted upon by a suitably qualified person.

as dave has advised,what is your post code.

Re: LG WM-1460F(H)D

Thanks for your comments Dave and Bryan. My post code is WA4 2BY. I do know an engineer but he has little if any experience with LG machines. Looking at the PCB I would have thought it was a matter of re-plugging like for like? Bryan, could you let me know how much the PCB is?

Re: LG WM-1460F(H)D

How old is your appliance ?.As if its under 2 years old then you will be covered for both parts and labour as long as you have the original purchase receipt,if its over 2 years then all you will e charged is the labour as long as you have purchase details ect.
If you still want the part then e-mailme at r600a@hotmail.com and i’ll send you the details
