A NorDmende WM 1201 WH will wash but will stop with its start/pause button flashing just before it is supposed to go into the spin cycle.
Selecting different spin speeds makes no difference.So far i have cleaned filter, checked free running of pump, removed machine top and blown down tube to air reservoir to remove any build up of obstruction and checked all connections.
It will kick into the lower (3/400?) spin cycle in the 60 degree wash setting and continue onto the rinses.
Hopefully someone can provide good advice on this as i am a pensioner caring for a severely disabled wife and need this machine twice weekly.
Re: NorDmende not spinning
Never worked on one,no nothing about them at all, but I`ve heard of the name,so here goes. Looks like a Vestel Turkish made machine or perhaps a Chinese one from their website. Possible it could be the pressure contacts switch stuck rather than the tube blocked up- I had one do this on a Tesco homebrand Vestel made machine for no apparent reason. The 300 rpm might be true, but it might really be less i.e. distrubtion speed and then fail to pick up on spin or simply do nothing. Or another way to look at it given the info that nothing is wrong at all but the machine is sensing that particular load is out of balance and so never spins ……impossible to say really but I had a stab at it. A pure guess: blow into the pressure switch and see if it clicks and then declicks if it`s a brick coloured round switch you`ll definitely hear it but if it`s a black and blue switch with 3/4 fine wires leading to it don`t because you`ll upset it! If you have the round brick coloured pressure switch and it is faulty usually the machine fills up with water and doesn`t stop!- you`ll get a flood- so be careful; it would prove a point.BOLuck
Re: NorDmende not spinning
The pressure switch is a small black cube. Marked with a 5 point star and states “Type 7640”.
It has 3 pink wires entering on terminals marked 5v,GND & out.
I have not blown into it yet as i would like to know first if that type is safe to do so.I have checked the motor brushes and they are only about 1/2 worn as yet.
Have looked for the Module on this model as another option could be “Dry Joints” but i guess it could be hidden behind the covers of the front controls.
Re: NorDmende not spinning
Sorry but that`s a new type of p/swt to me. I do not know. But taking a guess, yet again, I`d say that it looks like a variant of the blue and black p/swt I was on about, just a differing version on the same theme by the fact there are 3 wires all the same colour. And yes you could be right about the pcboard joints but that, based on most other stuff, is not that common. What it could be is an iffy pcb or even a motor wire, how many motor wires have you got in the motor block? If only six I`d doubt it is going to be the motor since it does tumble and sort of spins, if 7 wires, discounting any earth, that is where you want to have a good look before checking the pcb.
Re: NorDmende not spinning
I have ruled out that pressure switch as obviously it is working and only operating the water level and nothing else.(single in – single out)
As the Motor brushes are only partly worn, and it is going into the slow spin mode and attempting to kick into the high spin i have concluded that it is obviously a control system rather than the motor itself. (6 cable by the way)
This Model is a comparatively new one and the Module is rather compact. Quoted at €119, vat at 23{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} inc is rather steep.
Found a used module on ebay with the panel, controls etc. still attached and listed as “in working order” from a recycling white goods company in Belfast. I know i am taking a chance but paypal can get my money back if not. (Photo attached)
When it arrives i only have to slot it in and try it out.This will allow me some time to check my own module for dry joints etc.

Let us know whether the replacement board solves the problem please. There`s not alot let, so a recap:p/swt clicks in and out, no blockage in air trap- you can get the situation where the machine o/fills but doesn`t leak so you wouldn`t know, when the machine pumps out the p/swt air cannot escape from the p/swt so it is still made so the machine won`t spin-unlikely given the machines age usually only happens on old stuff. The motor and wires are ok,the machine does pump out,drum won`t spin with a good sized load, or with no load. Basing it on this your probably right and its the pcboard…………….hopefully!
Re: NorDmende not spinning
Brez, with power off to appliance when working on it, don’t blow into the pressure sensor device as it’ll more than likely damage it, blow down the pressure hose towards the chamber this will dislodge any gunge in pressure vessel that may be giving a false reading that appliance hasn’t completely drained.
Another thought, you say its a fairly new one, have these nordMende appliances not got a 3 year warranty on them.Re: NorDmende not spinning

Unfortunately not sce.
The board that arrived was WORSE than my own!
Thoroughly cleaned the connections and the plugs for them and applied connecting paste to ensure best connections before fitting it.
On ignition the initial pump run started, and ran, and ran….. nothing else!
Now! a good neighbor, who knows a guy in the trade is getting me a new board at cost price, so just waiting for the arrival of that.
@Seamy:
The usual, Machine broke down in December, the 3 Year warranty ran out in NOVEMBER! 😀Re: NorDmende not spinning
Oh my! The plot thickens!
The situation now is i have 3 pcb’s my own one, a used but guaranted working one from Belfast and a new one from Dublin.Using my own module i have a wash but no spin.
Using the module from Belfast, i only have initial pump run.
Using the module from Dublin – again just initial pump run!
Now if you look at the pic of the belfast module above, you will notice that the wires were cut rather than taking the time to unclip the plugs.
I did notice that while i was undoing the plugs on it, some wires were not going to the same plugs as per on my own module.All 3 boards are marked vestel and all 3 “Appear” the same.
Re: NorDmende not spinning
Just an update on the Situ, which may help someone in time to come regarding this model.
I have finally got her running as she was intended!
On my own pcb the relay that controls the selected spin speed was not engaging so that board is non-serviceable. I do believe though that this more than likely a dry joint. (will run around this board with the soldering iron when time allows-modern relays rarely break down!).
On the board from Belfast, it appears that the memory chip is stuck in the drain mode. I made many attempts of resetting the module including entering and exiting the child lock setting. (maybe use the relay for my own board-spare!)
Now, The interesting but confusing bit…
I have the new board from Dublin in but…
The small plug containing the 3 pink wires from the water pressure switch, no longer goes into the last 3 connections of S3 on the board, instead they go to the FIRST connections of S1. (this is how the wires were on the Belfast board when it arrived).BTW, Yes i did try this wiring pattern on the other Two boards without any success. Wiring it that way on my own board just runs the drain mode continuously.
As regards the Water Pressure Switch, i have been informed by a Nordmende agent that blowing into it is a waste of time and would make absolutely no difference. It is a c-type diaphragm, does NOT click and is completely dependable.
Was there 2 separate board manufacturers making the same boards in a different sequence? If patterns were changed, why? When?
The wires on the Belfast board had some wires differently coloured and the water pressure switch plug only had 2 wires so the gnd was not connected on the earler model!Re: NorDmende not spinning

Most likely the P.C.Bs have come from a different model, or a new type of P.C.B has been fitted after a certain production run of the model, manufacturersdo this regularly. You need to quote model & ser’ number when trying to purchase spares for “her” as obviously “she” is a feminine appliance.
Re: NorDmende not spinning
Looking for a replacement water pressure switch part #32025730 for this same machine as i have noticed this one is beginning to break down (makes contact only 2 out of every 3 washes.
and NO i did not blow into it as i would not risk the damage.
Even the Nordmende distributor in Dublin has not got one, said it could take up to 6 wks to get one.
