Re: Seme delivery times
The rot seems to have set in when it became Seme Nedis whoever ‘Nedis’ might be. shame really though because it was a really good firm.
I have sung their praises loudly on this site in times past – Their £12 carriage threshold was a bit unrealistic though and I could’nt see that lasting.
Having said that £25 is still pretty good and much better than most. I have found their delivery to be excellent in the past – almost always next day even when ordering up to 5PM. Up to now I have not had any probs in this area yet but will wait and see.

Re: INDESIT EVOLUTION
Yep, Daves blob on.
Easiest – try slipping the connectors on and off a few times, failing that –
carefully clean up the tracks at both ends and re-spring the idc connector pins with a small needle to tighten the fit.
If this does not work then you may have a dodgy eeprom (corrupted data) on the display module.
They should have renamed the eeprom’s on these machines MMMD’s

Re: WMA 33
The easiest way to check these is to slip the motor plug of the module and disregarding the three wires that go to the interlock (the end that has a coloured wire black or red usually) you should find continuity through every pin on the edge connector.
This checks out the motor and wiring harness in one go and is the easiest to get at. If everything checks out OK then your problem is on the module (assuming no intermittant fault and the tacho magnet is in place)).
Are you sure the module that you tried in is OK, because its usually a s/c motor triac.
Some of these modules have two triacs one for the main motor circuit and the other for motors that have a split field coil.
I had two the other week – same fault – triac
Most 16A triacs will work OK even though the gate trigger voltage might differ a bit usually I stick a BT139 in.

Is it a permenant wobbly or will the module function OK after the pump is sorted?
Just interested. 🙂
Re: Info request on Merloni hotoint modules
Hey Mike
Were all on all learning curve, I did,nt know about this stuff myself until a few months ago. Somebody on here put me on the right track.
Thats one of the really good things about UKWG we can all help each other out and learn off each other.
By pooling our knowledge we will all be in a much better position to handle new stuff as it comes along despite some not very nice manufacturers who withold nympho – sorry info – my mind keeps wandering!
Personally I have had some really heplfull info off guys on this site when I have been stuck, and I really appreciate that
Re: OK you clever dicks!
C’mon Dave – lets think about this!
A turd would never get through the drain hose 🙄
mmmmmmh! – it might have been a very thin one I suppose…………
It would have to be a very fast turd too……… reminds me of a little ditty I used to know.
The night was dark, the sky was too,
As down the street the s**t wagon flew,
It hit a bump a scream was heard,
A man was hit by a flying turd!I love poetry.

Re: Info request on Merloni hotoint modules
Iadom
I got a lot of practice writing as a technical author. 😉
On a more serious note (as if) do all these Merloni Hotpoint m/c use a three phase DC motor or just some models?
Are all the new Ariston / indesits the same.
By the way lmtgowi the three componants bolted to the heatsink are power transistors (MOSFETS or Bipolar) that make up the inverter stage that supply current to the motor phase windings. These are driven by a controller IC.

Re: OK you clever dicks!
Somebody, for some reason connected the drain hose to the water supply (maybe to try and clear a blockage ?) The back pressure was enough to force the ball past the retaining lip and into the tub. 😀
Well it sounds plausible ! 😮
Does’nt it? 😯
Wotcha mean ‘what a load of cr*p’ 😥
Re: Indesit WA155 f10: unsure of fault diagnosis
Hi Simon
I’me a bit perplexed – in your first post you said that you had refitted the old p. s/w and it was OK
Did the fault re-occur later?
I have had F10 faults which are track defects on the module which makes the controller think that there is a p.s/w problem when there is’nt. Its just a breakdown in the feedback circuit. But it seems that F10 signifies a complete loss of feedback from the p.s/w. This would happen with a bad contact in the p.s/w for instance (similar to a bad heater relay contact resulting in an F8 ). With the other p.s/w codes F4 & F5 the feedback is still present but it is receiving a different signal than it expects for that part of the program.

Re: Indesit W12SUK
yep! Thing is, i was stacking ‘z’s on the sofa for most of the evening woke up at 11pm bright eyed and ready for a hard session on UKWG.
And yes CPC have these at 92p + VAT
SW01454 (12v)
SW01455 (24v)Seme @ £1.35 + VAT (12v)
REL-11202
CDSL – almost certainly no part no though 😥

Re: Indesit W12SUK
Well i agree with you Chris, I have found F8 to usually be the relay.
The drive circuit from the microcontroller is pretty simple. Output is from pin 42 which goes to the IC ULN2003 pin 1. This device has seven high current darlington driver stages one of which is used to drive the heater relay coil. Output to the relay is on pin 16. The relay switches the neutral supply to the heater.
Feedback from the heater relay is through D1, R3 to pin 39 of the controller chip.
I reckon that the microcontroller switches on its output to the relay and monitors the feedback on pin 39. If the relay is sucessfully activated a return signal is received pulling pin 39 low. If there is no output then an F8 error condition is raised.
Obviously a failure of any of these componants will cause the problem, including a defective track, but the relay is prime suspect. As this is a simple on/off signal it’s not difficult to check through the circuit to trace the source of the fault.
Supply from the relay to the heater is through socket CN1.
Interestingly the other wire from CN1 goes to the pressure s/w and pulling this plug raises an F10 ?? (Pressure switch not sensing correctly) which is a bit of a mystery code as there are two other pressure s/w codes that seem to cover most problems.
F04 Pressure switch jammed on empty
F05 Pressure switch jammed on full(If you ever receive an F10 check the very narrow track that runs adjacent to CN1 connections. If the board becomes damp tracking can occur due to the close proximity.)
The processor will allow two attempts to pull CN1 plug and reconnect but aborts the program on the third try. I did wonder if this code might activate on a flood condition but now tend to favour it signalling a complete loss of feedback from the pressure s/w (but only guessing)
