Zan jetsystem 1400 FJR1454W pump 5 secs > St/pse flash.

[leavemetogetonwithit]

I went to this today. The brushes were down so I did them. (Type with terminals on side.)
Turn on to test. Skip to spin. Press start. Pumps 5 secs., stops and start/pause light flashes. Possibly also door clicked open, can’t remember.
Same on all programmes.
B****r! I thought. (Or words to that effect.) Miles from home and left my codes book at home. 😳
Managed to keep cool. No apparent insulation faults. Unplugged motor -> no change. Tested heater, recirc. pump, valves. Checked ntc connection. All OK. Door locking. No filter/ sump/ p/sw blockages.
Eased out main module by cutting two or three cable ties and releasing a few loom clamps and managed to get access to print side without disconnecting any of the wires. 8)
So what did I find? Clue is sort of in initial fault which I fixed. (See beginning of post.)
Left machine working perfectly.

Answers on a postcard.
Mike.

Carbon deposit on board creating an un-wanted circuit?

🙁
I must have made it too easy. 😆
Good thing I didn’t offer a prize!

Actually there was quite a bit of black dust throughout the machine.
I suppose it gets attracted to certain pcb tracks by the charge. It wouldn’t surprise me if this is responsible for a lot of puzzling faults. I recall Tony advising somewhere to scrub boards and dry them.

AARgghhh!
Wake up this morning to find message on answerphone.
Machine completed two washes perfectly and is now doing same as before.
Oh well, back Monday with the service manual.

Well I went back. Did the diagnostics and got E34. Manual said that this is incongruity between anal-logic (sp?) and conventional pressure switches.
Cleared last error, disconnected p/sw hoses and tried again. Still no joy.
Decided to whip board out again and have another look.
Well, you may remember, but probably not, that in my earlier post I said how I’d cleared a massive carbon build up off the print side, without troubling to access the component side of the board. This time I opened it up fully and found, to my delight, almost as much of the black stuff on that side. Bingo! I thought and diligently paint brushed it all away and re-installed board.
But to my horror, the fault persisted and no matter how many times I did the diagnostics and cleared last error and fiddled about with loom positions, it would not go away 😡 .
Customer appears on scene at this point and asks about progress. I explain situation and suggest maybe they could hang on just till the end of the week by which time I may well have more info (and time+energy to get back out that way.) But the lady of the small country mansion with huge gardens is looking decidedly :nono: . He says, “Oh well, you did your best. Here, have some more money :D. Do you think Miele is any good?”
So there’s another one ended up on the scrapheap and me thinking, “if only I could have had a bit more time at it.”

Have you checked if the heater is open circuit or down to earth?

Thanks Seamy. I did that on previous visit. I’m well aware of the problems they cause. Heater was not being activated (warming up) during first five seconds of start up though and was meggering in the hundreds of Mohms cold. Also this is a soft water area = I’ve only had to change a dozen wash elements in the last ten years. (And maybe two pressure switches. One being just the other day.)
I’ve since done a search on E34 and it seems it’s a “contentious” fault. I’ll be better prepared next time.
The thing’s effectively on its way to the scrapyard as of now anyway. I’m musing about whether it’s worth me renting a workshop so I could abduct these difficult ones but on the whole, I think not.
I might get myself a Blackberry though. The guy was showing me his after I got him to take a photo of the carbon deposit and it would be useful for accessing this site while on the move. (Would have to get some stronger specs though :lol:)

worth letting the heater warm up before you megger it …..always find E34 is low insulation heater….also check for holes rubbed in pressure hoses!

Hi Big Chris. I don’t think this one would have been the element. The motor might be a possibility as it had just had it’s first new brushes and there was plenty of carbon dust around. Having read through a good many E34 threads earlier this evening I should have looked for dry joints round the relays, colourcatchers in the sump (but I think I covered that by disconnecting the p/sw hoses 😉 ) and the electronic p/sw has often been implicated. So I’m really looking forward to when I get another E34.
Mike.
