Indesit pressure switch

[clivesound]

Hi, I have an Indesit IWDC6125 washer dryer. It sticks in fill/empty cycle
without turning just repeats cycle endlessly. I had an engineer come around who told me it was the pressure switch at the top of the machine.
He demonstrated with a multimeter why it didn’t work. Came back changed it, charged me £120 total , still didn’t, told me that although the new switch works the machine has another fault as well. He accidentally left the old switch here. Both switches appear to operate identically.

My question is this, It has 3 pins, I touch left hand 2 with multimeter whilst blowing, resistance goes to zero. Do the same on the right hand two and nothing happens blowing either way. Should it? Could the new switch be faulty as well or was their nothing wrong with old one and it’s another fault.

Thanks in advance for any help.

Re: Indesit pressure switch

At a guess, I’d reckon that the pressure switch wasn’t the problem in the first place.

And, it seems a tad expensive…

It’s a low voltage pressure sensor by the looks of it, the resistance should change as the pressure changes.

Surely you didn’t pay the £120 ?

Re: Indesit pressure switch

Thanks for your reply, I feel that you’re right.
I paid him £60. Told him I’d pay the rest if he can come back and diagnose the other problem. It was only when he left that I checked them both. It does seem odd though that there’s 3 pins attached to 3 wires and when you blow in it audibly clicks and goes to zero with 1 and 2 connected to multimeter but pin 2 and 3 seem to do nothing blowing with audible click either way.
Is pin 3 just there as type of dummy support perhaps and the third wire just happens to be there as it’s a standard lead?

Moved to correct forum, I guess Ken missed the fact that you posted this in the dishwasher forum.

You will only hear one click, the second circuit is for the overfill mode, it doesn’t click.

If it sticks like this as soon as you switch it on then that is a common main pcb fault.

If it does the first wash cycle then sticks in this way during the rinses without the drain pump running then it’s likely to be your plumbing.

Re: Indesit pressure switch

Oops, sorry for posting in the wrong place before.

Thank you guys so much for your advice.
I’m not a washing machine or plumbing engineer. I’m afraid I’m just a sound engineer but you’ve cleared some things up for me.

Before I read the posts I tried a little experiment. I removed the pressure switch and put a two way manual electrical switch over the 3 wires with 2 as the common. Switching this to pins 1 and 2 when the machine looked full enough set the whole thing in motion and it did a complete cycle. This confused me a little until I read your posts. After reading them I re attached the pressure switch and listened more closely. I realised that amongst all the clicks and whirrs,the switch wasn’t doing anything physically.

I therefore unplugged the hose and put a small hose onto the pressure switch, blowing into it had the same effect as the electric switch, I blew, sealed it, it ran a whole cycle. I’m thinking, therefore, that, as you said, it’s not the switch. Obviously no air pressure is coming out of the tub.
Would I be right in thinking that the tube or valve is therefore physically blocked. If so I shall ring the engineer, explain and ask him to unblock it.
Thank so much…. The things we do for the dear missus!

Re: Indesit pressure switch

If the lower end of the pressure hose is blocked then you are in trouble, the pressure hose is attached to the pressure chamber which on these machines is part of the totally sealed outer drum.

Lets just say that Indesit to Miele is as Amstrad is to Marshall. :rolls:

Re: Indesit pressure switch

had a few of this problem where the pressure bell was integral part of tub and blocked
I found if I poured about half a bucket of water in the drum, then disconnect hose from pressure switch, then blow and suck the water in and out of the bell to try to wash it out as best u can. it may not clean it completely but its cheaper than a new drum

Re: Indesit pressure switch

Thanks. I’ll try the bucket of water and blowing in and out tonight.

Aaaah Amstrad, brings back memories. I remember getting one as a teen.
I think my mum got it at Dixons. I got it home and to my eyes then it looked amazing. Loads of tweeters and woofers etc. Really excited, I put a record on and it sounded not to good…. Being inquisitive I took the back off one of the speakers only to find that all the tweeters and woofers were fake. It just had one speaker in it!! I used the speaker boxes and rebuilt them with stuff from Maplins.

I suppose Sugar was the Gerald Ratner of hi fi’s. Without the “gaffs”.
Oops, that’s my chances on The Apprentice out the window!

Wasn’t disappointed when I got my first little Marshall guitar amp though.

Thanks again for your ideas.
