I'm a newbie so please be gentle...

Help me please - I'm going loopy!!!

My LG F1480YD5 washer dryer is tripping the RCD on my house consumer unit due to water travelling up the pressure tube and spraying on the power filter pcb during the spin cycle.

So far, I have (here we go...):

Replaced the power filter pcb, replaced the pressure switch, replaced both impeller pumps, removed and cleaned out the rubber boot between the pumps and filter, removed and cleaned the filter, removed and cleaned the drain pipe and I have cleaned out the outlet pipe in my kitchen with is only for the washer dryer. 

When the RCD trips, I remove the top cover from the washer dryer, remove the power filter pcb and dry it and the associated connectors with a hairdryer for a few minutes, put it all back together again and hey presto, it works!

Can anyone shed any light on this for me please?

Finally I would like to say all help will be greatly appreciated.

Cheers

99% of the time it does this during the final spin cycle, on the odd 1% it does this a minute or two after the wash cycle has ended.

If I'm quick enough (like this evening) I can see the water on the underside of the cover and directly around the pressure switch area. 

It is only 3 years old, cost £689 and LG UK have said "Sorry, we're not interested" Oh well, you live and learn eh?

Hi there. Water should not travel up the pressure tube. Only air. Water rises in the base of the tube where it enters the pressure chamber bottle, but then as the water level rises in the drum it should push air up the thin tube. If water is going up that tube and coming out of the top there must be an air leak in the thin tube. If the pressure tubing is long enough cut off 5 - 10 mm of the tube and reattach it and make sure the clip is on properly.

Andy, thanks for the reply.

I have removed the tube completely and blown down it with my thumb over the end and it was completely air tight.

However, I did re-attach it to the pressure switch and seal it with silicone sealer to ensure an air tight seal at the pressure switch only.

Any other ideas? 

My credit card is going to have to make an appearance soon to buy a replacement machine and being a Yorkshireman, I am already having sleepless nights!!!

The air leak is usually where the tubing fits onto the pressure chamber or switch, and that can't be tested for by blowing down the tube. The only thing that could cause water to rise right up the pressure tubing is air leaking from the system. If it's not the tubing or connections either end it could be the pressure switch itself.

Hope this thread is still active.

I too have had the same issue but I have found the root cause to be the gaping hole in the drum enclosure underneath the dryer heater(see attached pic) allowing water to be sprayed out and covering the pressure switch and the mains filter and blowing the fuse. This looks to me like it is a design fault.. The heat shield isn't large enough.

Hello PendlePete. That looks bad. It's hard to judge from a photo and without being able to examine the machine but that's definitely something that should not happen. It's possible there is a design fault if the plastic is exposed to excess heat, or possibly something went wrong when it was manufactured.

Hi PendlePete and thank you for taking the time to reply to my post.

After many, many months of banging my head against a brick wall with this damn washer dryer I threw in the towel and bought a new Indesit washing machine for £210 - simple and basic but it does the job, very well actually. 

I decided that if I can't have my £680 LG Washer Dryer then neither can anyone else and proceeded to strip it to the bone (childish I know, but extremely therapeutic if not very expensive). Then as I was doing this the real fault appeared to say "Hello!"

(see pic) - at this point many, many 'special' engineering words were said out loud in Punjabi as well as English. 

Well it was down to an extremely poor design by LG and has put me off buying any of their fanciful products in the future due to their sheer lack of after sales service and bad attitude. 

Cheers and thanks for sharing.

Thanks for the post Tronix.

Did you contact LG about this fault?

I contacted them a couple of weeks ago but not heard owt since. 

I too have been put off from buying LG products.

I had the exact same issue. The RCD tripping was caused by water splashing out here and hitting the filter coil. Replaced that with a part from espares and I bought a replacement drum for 23 GBP on eBay and its been fine ever since.

Going to contact LG but have zero hope of getting anywhere. 

Everyone who has this washer dryer will eventually have this issue so theres got to be more people out there. Be good to find them and get a crowd together :)

hi guys my one hasn't gone as far as making a hole but i noticed the burnt mark on the same casing. LG engineer came out the guy was useless lucky I had taken pictures myself which he ended up using to writing his report.

LG have offered £70 odd pounds to settle this due to amount of yrs I have owned washer dryer (5 and half years). But im not accepting because like most im sure will agree this is a design fault you can clearly see the heat shield is not long enough.

Im now waiting on a manager from the resolutions department to call me to discuss further (don't think im getting anywhere though) any advise would be appreciated.

If you can't see anything obvious then it's unlikely you will be able to troubleshoot this fault. Here is my article about the problem of washing machine tripping electrics or fusing
