Re: ISE w288eco – Drum banging + Cycle doesn’t finish

Hi Ian

I would be agreeing with Ken that it is either sensing out of balance or that the appliance is sensing that there is still some water left in the appliance. When did you last carry out a service wash ? and how often ?.
If the appliance is getting upto full speed when empty and no clothes then I would assume with a fairly good bet that the component sides are working,I.E. motor,pump,board. that leaves the pressure switch operated by sensing water level,this will also stop the motor from spinning fully,this can be confused by scum which forms into a dirty cream cheese substance when the machine has not had service washes carried out or when liquid detergents are used.

If the machine spins once it has had the pressure hose removed them the later would be a likely cause.

hi.

Further update……looong post again sorry….

The retailer we bought it from came out to look on Monday for their call out fee. The engineer tested various components, couldn’t find anything wrong and put the machine back together. Then…. I kid yea not.. the machine started spinning. After he left, my wife ran a wash which went through to completion. Hurrah. When I got back from work and tried the spin program….it still…. worked ! Double hurrah…. This was however, to be short lived…..

The very next morning, the machine was running a wool program. Guess what, the problem returned and it would not spin… and would not complete its wash. Trying the other programs the problem was back but as before, it will spin from the service menu.

I do wonder whether we have an intermittent wiring fault or something on the main controller that the engineer disturbed when he tested the components and put the machine back together.

We are incredibly frustrated as I’m starting to think we could be into the realms of replacing one or more of these components… or god forbid all three/four until we nail the culprit…..

The main CPU board – Not sending the right signal to the motor controller.
The motor controller – Could be intermittent fault in this controller.
The motor itself – Remember this works on service mode…
Wiring loom – Although the cabling looks ok… there could be a break in one of the wires.

These components aren’t cheap…

I’m trying to get the engineer back to see the machine misbehaving and to be able to do some diagnostics whilst it exhibits the lack of spin cycle. He did mention he felt the motor was running a bit warmer than expected which could indicate a problem but doesn’t explain why it would work from the service menu.

Does anyone know what signal is sent down the three wires from the main board to the motor controller. I’m tempted to stick my oscilloscope on it but would be useful understanding what each of the three wires carries. I’m guessing ground, signal and some sort of feed back signal. (or ground, +ve, signal).

Any additional information very gratefully received.

Regards

Ian

Re: ISE w288eco – Drum banging + Cycle doesn’t finish

Hi kwatt,

Service engineer is awaiting a reply from gorenje wrt replacement availibility and cost of cpu board and motor. He’s leaning towards the cpu board.

Three things,
i) The board on your store for 157 pounds states its for w288. I presume thats the w288 eco model that we have ? This is the guy https://shop.ukwhitegoods.co.uk/8801513 … ntrol-unit
ii) I’m inclined to buy it from the site today rather than wait for the engineer to source parts from Gorenje. Do you have any view on this approach ? If the cpu swap out doesn’t work then its new machine time.
iii) DO you know which motor control module is the one for the w288eco ? w1606 or w1607 ?

thanks again and regards

Bryan,

Its not the pressure hose. Checked for blockage and the relay clicks as expected on fill/drain.

Thanks

Ian

Re: ISE w288eco – Drum banging + Cycle doesn’t finish

I can confirm that we do have stock of that part.

What I can’t do is confirm that’s the problem obviously as previous.

Re: ISE w288eco – Drum banging + Cycle doesn’t finish

Logic says it has to be a pressure switch problem. From the posts so far I cannot believe it a CPU issue at all, that’s a nonesense. Buy one at your peril. 🙁

Re: ISE w288eco – Drum banging + Cycle doesn’t finish

OK. To answer various questions…

The pressure switch is not faulty. I can hear the relay click when it fills and click again when it drains. The connectors all show the right voltage when plugged in consistent with the function of the relay. There is a fourth lead that looks like its for over pressure as you really have to push the switch in some more to make contact. I couldn’t do this just by blowing into the pressure switch so I’m curious to know what this is.
There is another pressure sensor on the cpu board itself which is probably used to fine tune additional water and maybe used by the controller board instead of the main pressure switch which controls the heater. I did wonder if this was the culprit hence the possibility of the main board being the problem.

The main board now doesn’t look to be the problem either. Tried the new one and same behaviour. I know you were all saying it can’t be the main board but something somewhere is awry.

I will do another wiring check to see if there is a dodgy wire/connection. When the engineer came round the machine decided to start working after he’d tested some components and plugged it all back together. I lasted two washes before giving up the ghost and return to this behaviour.

I’ll be feeding back the new information to the engineer for a return visit but it now looks like new washing machine time. Sadly this one won’t cost a grand…..

Re: ISE w288eco – Drum banging + Cycle doesn’t finish

So Martin.

Can you explain why the machine spins from the service menu but doesn’t from a standard program ?
Also, the programs never finish… they just get to 1min to go never having done a full spin.
You all say pressure sensor and yet this seems to check out.

What would you do ? Everyone is a little flummoxed by this one.

Regards

Re: ISE w288eco – Drum banging + Cycle doesn’t finish

Hmm! Did engineer test the machine under load- that`s the time it worked or did he test it empty. It is possible that when under load the chip that senses any out of balance is at fault and therefore this sounds like a pcb fault. Another thing to consider is if the heater is trickling to earth which on the face of you`d expect the trip to go off but not necessarily, the earth fault can back feed in to the pcb using that a restistor and confuses it temporarily- this happens on Hoovers Candy and Zanussi stuff and an ever increasing amount of modern contraptions too. Neither would flash up an error code and I wouldn`t expect it to, if one of these two ideas is right or even both faults acting simultaneously, that your machine would either. If you have a rinse and spin only programme you could try disconnecting the heater wires and isolating them/insulating with tape get a normal size load-towels for example, unlike perhaps the usual small wool size load, then try it and see what happens from rinse and spin. You may have a megger if you have megger the heating element- I`ve had the slightest of an earth reading, cold, cause all sorts of programme problems. Generally the more time a faulty heater is on when its gone up the creek the bigger the earth fault reading over that period of time just in the same way you can test a cooker element cold and nothing much may show up it`ll only show up after a few minutes as its getting really hot- elements actually can fail in some odd ways- even had then to earth and acting as a 1.7v battery before of all things.

Re: ISE w288eco – Drum banging + Cycle doesn’t finish

Thanks for your comments totalshambles. The same behaviour is evident on the spin and rinse cycles whether fully loaded or not.

Now here is something that I’m completely and utterly bemused at….. I’ve got the thing to run its program on rinse and spin programs so far by doing the following….

Start the program… wait say 5 seconds… then stop the program by pressing and holding the start/stop button. Then immediately after the program has stopped, press the start button again to run the same program.

I’m going to test on the quick wash and then try the longer washes. I’ll feed back shortly.

Any ideas gratefully received…. my inclination is that some start up check with say the motor controller is being bypassed with the restart…. so could be the motor controller.

Remember we’ve tested a new main control board and we see the same behaviour.

Re: ISE w288eco – Drum banging + Cycle doesn’t finish

OK latest update. Good news I think…..

My previous note about stopping and restarting the cycle stopped working after a couple of goes. Must have been a fluke.

The machine did decide to spin once since doing a spin. Never again.

So my last ditch attempt to throw some money at it before throwing in the towel and buying a new machine resulted I’m the purchase of the motor controller unit. Also called the inverter. This was duly fitted and it appears to work. I’ve only tested it on spin hence I’m not whooping for joy just yet…

I will feed back after its been through a few wash cycles.

Thanks all for your comments and feedback.

Re: ISE w288eco – Drum banging + Cycle doesn’t finish

Update as promised

Washing machine is now working OK. If anything its slightly quieter which could point to an issue with the balancing process on the old motor controller board.

I think the issue has been there from day 1 as the issue has occurred intermittently through the life of this machine.

Thanks all and I hope this information may be of use to anyone else with an ise machine with similar issue.
