John Lewis JLWD1408 not moving from wash cycle to rinse

[Evil_dave]

Hi everyone,
I’m having problems with my John Lewis JLWD1408 machine.
A couple of months back it stopped moving from the wash cycle to the rinse cycle – just draining then stopping. This happens pretty much every time. If I try manually turning it on to a rinse cycle it stops after 30 seconds. Strangely if I leave the machine for 30 mins or so, it will start a rinse cycle ok. It also seems to have no problem with a 30 minute programme.

I did the code diagnosis and it came up with E84 – fault with the recirculating triac. After getting a fixed price repair to come out (and me telling him the error code) and waiting 2 months for a part, new PCBs were fitted today. However this didn’t fix the issue.

Can anyone help? I’m sure if it needs more work I can get it done under the fixed price repair, which so far hasn’t repaired it, but I need suggestions as to what could be at fault.

Many thanks.

Dave, when it washes does the recirculating pump actually run? Is water flowing into the drum from the top of the door rubber as it tumbles?

Hi Martin,
Yes the recirculating pump is working and water comes from the outlet at the top of the door. I’ve even done the recirculation test cycle and that all seemed fine.

So that proves the error code E84 bears no relation to the existing problem. Makes me question why the hell the guy changed the PCB purely on the strength of that error code I presume…..very odd they should do that.

Makes me wonder if they have checked anything out in the machine, like the water and dryer heaters? The analogue pressure switch? The air pressure chamber and so on?

Any earth leakage can result in the PCB spouting out random irrelevant error codes. Error codes are a rough guide as to what MAY be wrong and NOT a certainty.

Hmmmmm? 🙁

Yeah – it’s stumped me too!

I was wondering if it could be the pressure switches, not realising that it had completely drained.

What’s the best way to see if there is any blockage? Gunk or scale?
I’ve taken off the pressure switch and blew/sucked a couple of times. Equally I’ve blown down the pressure tube.

Re: John Lewis JLWD1408 not moving from wash cycle to rinse

Removing the rear half of the cabinet is necessary to access these components. Where you can fully check the pressure systems as well as the heater functions. I’m guessing the repair guy didn’t do any such things?

Re: John Lewis JLWD1408 not moving from wash cycle to rinse

The repair company are now sending around one of their “senior repair engineers”. I’m hoping that he will be able to do a better diagnostic of the fault.

So your top tip for checking would be around the pressure sensor and heating elements?

Yes!

Re: John Lewis JLWD1408 not moving from wash cycle to rinse

Well the engineer they sent this time sounded more competent. There was the clanking of metal panels and the beeping of a multimeter.

Latest diagnosis is the heater controller. Part is now on order. I’m sure I will post an update after my next engineer visit.

Re: John Lewis JLWD1408 not moving from wash cycle to rinse

Would suspect the dryer heater to be low to ground. If it was meggered it should show up faulty.
This theory can be tested by removing the cables off the dryer heater and taping them up safely so they dont touch anything.
Run the machine on wash only and if it does the programme ok where it previously was sticking it may point to the faulty part.

Power off of course when working on appliance, covers back on if doing any test washes.

Re: John Lewis JLWD1408 not moving from wash cycle to rinse

Okay, so another visit from an engineer later and another new part – to resolve the sensor on the heater element, which was the last diagnosis.

Fault still present….

I’m sure the fault has something to do with the pressure switch to detect that the machine has correctly drained. But now I’m going to have to arrange for yet another visit. Perhaps this time I will not let the engineer leave until he has seen the machine fail after 29 minutes.

Sigh…

Don’t handcuff the poor soul to the washing machine but rather he stick around a while, enjoying a cup of tea and a slice of jam sponge whilst the machine goes through its paces. 😀

Re: John Lewis JLWD1408 not moving from wash cycle to rinse

Well engineer number 3 inspired me with confidence. Immediately went to the diagnostic menus.
What he did discover (which I had spotted before, but didn’t realise what it meant) is that the diagnostic cycles weren’t displaying spin speed / temperature on the display. Because these perimeters are passed back from the door lock, he thinks this may well be where the fault is originating from (along with the fact of the other components that have already been replaced)

Parts are now on order and I’m awaiting visit number 6 for them to be fitted. Does this diagnosis sound about right to everyone?

Performing the diagnostics cycle is a fundamental requirement with these machines. Each stage during the procedure checks the functions of each component and process. Any error detected would be displayed.

Ultimately it is just a guide as other factors can lead to false readings so we can only hope the engineers conclusions will be realised on his return. We’ll keep our fingers crossed for you meanwhile. 😀

Re: John Lewis JLWD1408 not moving from wash cycle to rinse

I’ve finally got a working machine.

The recirculation pump and the door lock were both changed, so I don’t know which was the guilty party.
I wasn’t that hopeful as the diagnostic mode didn’t display rpm / temp etc – but that isn’t affecting the machine. The repair company didn’t exactly send their top engineer this time, and I had to reset the old error code after they left – but as the machine now works I can somewhat overlook this. Especially as I’ve ended up with 2 new PCBs and a heater element in addition to the recirculation pump and door lock.

Thanks to all who have given their input. Hopefully this will also help others if they have the same symptoms.
