Re: ISE 1606 fault part 2

Jumpty

You say clicks waits 20s then clicks then stops.

Is the water level OK from the test menu ? In our ise w288 the heater wire goes through the level/pressure sensor. This appeared to be a mechanical safety switch to ensure there was water in the drum beforr allowing current to the heater itself. Might be something similar in yours to check. You can hear a very faint click as the relay activates when the water fills up. The main level sensing is done on the control panel.

Re: ISE 1606W fault

OK rereading your model is wm25. Look further down the linky to a bunch of PDF links. One of these is service manual for wm25 range. This has a test program sequence… Looks like it might be useful. Apologies if you’ve already been here !

Re: ISE 1606W fault

Hi. We had lots of fun with our ise w288 which turned out to be the MCU.

Can you access the service menu and see if the machine will actuate the motor or spin the motor. On the 288 you switched it off, held one of the buttons, switched back on and pressed the button 3 times. On yours it might be 5 times. This accesses various service menus. If you can get the machine to move or spin then it means the motor is OK ish.

Although it won’t fix the issue it might help with your diagnostic.

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.

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

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

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.

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

Bryan,

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

Thanks

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

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

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

I see. thanks for info. So the machine talks to the motor down the three wires and tells it how fast to spin presumably with PCM or voltage level. Does the motor talk back re out of balance etc ? if I can get an oscilloscope on the wires then I can get an idea if there is any difference between the service menu spin and the program slow spin.

From the service menu you have to operate the drain before the spin… interesting.. even if there isn’t really any water in it… but it will spin up to full speed.

I do need to make a decision on whether to get an engineer in, starting throwing parts at it (ie circuit board) or, and it pains me to say this, discard it.

As an update on a typical wash cycle as I’m sitting here typing..

Washing machine is running, heater is heating nicely, drum is agitating, drain is not running. All normal in the land of washing. Then it gets to the bit where it would spin. Drain starts, water drains away and it spins very slowly ie 100rpm. Then stops. agitates..then spins slowly…..etc etc etc…repeats….all the while the drain pump is running. This continues…draining constantly.. agitating.. slow spinning until the timer has 1min to go and still continues. The machine has to be stopped by holding the stop / start button down. I’ve checked and there is minimal water left in by opening the little drain at the front so it is draining nicely.

This tells me it gets stuck at the first wash phase… and never gets to a rinse phase.

I’m mulling over stumping up for the circuit board on your website. If it is this then great.

What would you recommend Kevin ?

Apologies for the looong post.

Thanks

ian

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

Hi
One other thing to note. If you choose the spin program it drains constantly, agitates and puts in a very slow spin. Never gets over about 100 rpm.

No emp pulse I’m afraid. Unless the kids have been doing some very advanced science at primary school !

How does the machine detect an imbalance ?

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

Hi Martin.

Checked the hose where it goes under the drum. Its all clear.

Thanks

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

Hi Mr Watt.

Thermister checks out. 6k at room temp…dropping to 4k when I put my hand on it for a bit ! Not sure what the specs are for this part but it seems to behave as an NTC should do.

The pressure sensor seems ok. I can feel the relay click as the water fills up. Also gently blowing in the pipe presses the diaphragm and operates the relay. Something that erks me… after having a look inside one of the connectors will never make or break contact. It seems to be wired to make when the relay is activated but the gap is too large to make the connection. Its N16 on the wiring diagram.

So I’m at a loss really. There just doesn’t seem much to go wrong…….

The pressure sensor on the board seems to be where the logic resides that determines when the water is empty or full. I can pull the connector from the main diaphragm and it still knows when to stop filling.

The big diaphragm pressure switch seems to allows the heater on only when there is water in. A safety feature perhaps.

Stumped…..

There is a water inlet error from the service menu.

Any ideas ?
